Faced with the report\u2019s overwhelming evidence of massive interference \u2013 and no doubt in order to preempt these highly negative results &#8212; LightSquared simultaneously released a 37 page \u201cRecommendation\u201d document (RD) that it developed totally outside of the Technical Working Group established to collaboratively study the problem.<\/p>\n<p>In that document, LightSquared proposed an entirely new deployment scenario, not included in the initial scope of the working group analysis, which would not use the Upper MSS band at all, and a series of mitigation measures \u2013 many of which were never disclosed or discussed during the four month working group study process.\u00a0 Further, the document tries to blame the \u201ccommercial GPS industry\u201d for any interference caused by its operations, and also claims, without citation to the working group study or any other supporting data, that its proposal will solve interference for 99 percent of GPS receivers.<\/p>\n<p>The utter failure of LightSquared\u2019s initial deployment plans to pass interference tests raises fundamental questions about the representations LightSquared made to the FCC prior to its January 2011 decision that convinced the FCC to grant the waiver and convene the interference study process in the first place, and raises significant questions about the credibility of LightSquared\u2019s various claims and whether they hold up to scrutiny.<\/p>\n<p>The current strong indication is that whatever LightSquared told the FCC prior to January 2011 was highly inaccurate, to a degree that verges on negligence. These questions logically follow from the failure of the original deployment plan: Was LightSquared transparent in its dealings with the FCC? In other words, what did LightSquared know, and when did it know it?<\/p>\n<ul>\n<li>In all of its documents and public statements, LightSquared claims a long history of familiarity with the technical rules of the MSS band and a wealth of technical expertise on interference issues.\u00a0 LightSquared is clearly the most knowledgeable about its own network technology, and also claims to be intimately familiar with prior proceedings relating to MSS interference and GPS.\u00a0 And it appears to claim that it has been working on these plans for years.\u00a0 Yet, in February 2011 it proposed only deployment scenarios which used the upper MSS bands, which overwhelming technical evidence shows will cause massive interference to every GPS receiver studied.<\/li>\n<li>This raises a variety of questions: Did LightSquared not know that its proposed upper MSS band operations would cause interference? If it didn\u2019t know, that places its technical competence in severe doubt.\u00a0 Did LightSquared know, or have very strong reason to believe, before January 2011 that massive interference would result? If so, why did it not disclose this to the FCC?<\/li>\n<li>There certainly was ample available evidence that harmful interference would result. The US GPS Council knew, and presented testing results and analysis demonstrating this interference to the FCC in both December 2010 and January 2011.\u00a0 So did major U.S. government departments and agencies, which communicated serious concerns to the FCC in a formal letter in January 2011.\u00a0 LightSquared\u2019s reaction? It dismissed these findings out of hand.<\/li>\n<\/ul>\n<p>Since LightSquared was completely wrong in formulating its initial deployment plans and claiming that they would not cause interference, why should the company\u2019s reassuring technical claims about its \u201cnew\u201d deployment plan be given credibility?\u00a0 LightSquared\u2019s \u201crecommendation\u201d document makes a host of other inaccurate or misleading statements, and a number of its major misstatements are discussed below. The bottom line is that, just as LightSquared was wrong in 2010 and the first six months of 2011, it is wrong now.<\/p>\n<p><strong>Statement 1:\u00a0 The Recommendation Document mischaracterizes the GPS industry\u2019s position, claiming that the industry is trying to force LightSquared to buy other spectrum or go out of business:<\/strong><\/p>\n<p>\u201c[T]he commercial GPS device industry now argues that LightSquared should not be permitted to operate its L-band terrestrial network on its authorized frequencies but, rather, should have to find or buy new frequencies. . . .This choice would doom an innovative American start-up company that has devoted more than 10 years of effort and billions of dollars in reliance on explicit regulations and authorizations permitting it to proceed as planned with a vital new wireless network.\u201d RD p. 3<\/p>\n<p>\u201cLightSquared must begin to deploy its network immediately or it may not survive.\u201d\u00a0 RD p. 24<\/p>\n<p><strong>The Facts:<\/strong> The Coalition to Save Our GPS has simply said that until it can be <em>conclusively <\/em>shown that there will be no interference to critical GPS uses, LightSquared should not be allowed to deploy in the upper <em>or<\/em> lower MSS band.\u00a0 Unless and until that is demonstrated, LightSquared already has other spectrum and should use it.\u00a0 LightSquared\u2019s website states that:<\/p>\n<p><strong>LightSquared<\/strong><strong> <\/strong>already owns valuable high quality spectrum assets, including 59 MHz of nationwide ubiquitous spectrum in an advantageous frequency position. <em>Viewable at: <\/em><a href=\"http:\/\/www.lightsquared.com\/about-us\/our-investor\">http:\/\/www.lightsquared.com\/about-us\/our-investor<\/a><\/p>\n<p>The Upper and Lower MSS band together account for 20 MHz of spectrum.\u00a0 This leaves 39 MHz of \u201chigh quality spectrum assets,\u201d to which LightSquared asserts it has access, available to be used for initial deployment.\u00a0 Since the RD clearly indicates that only 20 MHz of spectrum is needed for initial deployment, <a title=\"\" href=\"#_ftn1\">[1]<\/a>\u00a0 LightSquared already has ample spectrum to support deployment without using any of the MSS Upper or Lower band. In any case, to allow for a clear understanding of the impact of the present proceeding on its plans, LightSquared should provide a full and detailed accounting of its spectrum holdings instead of painting baseless \u201cdoom and gloom\u201d scenarios.<\/p>\n<p><strong>Statement 2:\u00a0 The Recommendation Document falsely implies that this is a fight between LightSquared and the \u201ccommercial GPS industry,\u201d and that only the \u201ccommercial GPS industry\u201d has raised interference objections to LightSquared\u2019s plans:<\/strong><\/p>\n<p>\u201c[T]he commercial GPS device industry wants the Commission to shut down an unprecedented effort to establish a nationwide wireless broadband network built with private funding.\u201d RD p. 4<\/p>\n<p><strong>The Facts:<\/strong>\u00a0 The Coalition to Save Our GPS was founded initially by leading GPS manufacturers, but it has grown to include includes companies and trade associations cutting across virtually every sector of the US economy.\u00a0 \u00a0Its members include: the Aeronautical Repair Station Association (ARSA), AGCO, Agricultural Retailers Association (ARA), Air Transport Association (ATA), Aircraft Electronics Association (AEA), Aircraft Owners and Pilots Association (AOPA), Air Line Pilots Association, International (ALPA), American Association of State Highway and Transportation Officials (AASHTO), American Petroleum Institute (API), American Car Rental Association (ACRA), American Congress on Surveying and Mapping (ACSM), American Council of Engineering Companies\/Council of Professional Surveyors (ACEC\/COPS), American Rental Association (ARA), Associated Equipment Distributors (AED), Associated General Contractors of America to the Coalition, Association for Unmanned Vehicle Systems International (AUVSI), Association of American Geographers (AAG), Association of American Railroads (AAR), Association of Equipment Manufacturers (AEM), ATX Group, Avidyne Corporation, BoatU.S. &#8211; The Boat Owners Association of The United States, California Land Surveyors Association, California Space Authority (CSA), Canadian Owners and Pilots Association (COPA), Case New Holland, Caterpillar, Deere &amp; Company, Delta Air Lines, Edison Electric Institute (EEI), Equipped to Survive Foundation, Inc.

Their receivers employ wideband front-ends in order to increase precision and in order to receive satellite augmentation signals throughout the 1525-1559 MHz L-Band.\u00a0 By failing to build receivers resistant to lawful transmissions in an adjacent band, GPS manufacturers have effectively appropriated LightSquared\u2019s L-band spectrum.\u201d\u00a0 RD p. 18<\/p>\n<p>\u201c[I]t is inescapable that it is [the GPS manufacturers\u2019] disregard for the Commission\u2019s policies regarding the immunity of receivers to transmissions in nearby frequency bands that is the source of the technical problem.\u201d\u00a0 RD p. 2<\/p>\n<p><strong>The Facts:\u00a0 <\/strong>Many high precision GPS are in fact intentionally designed to receive signals in the MSS band, but not because GPS manufacturers intentionally \u201cfail[ed] to build receivers resistant to lawful transmissions\u201d in this band.\u00a0 Rather, many high precision receivers are designed this way to take advantage of services that LightSquared itself provides, as does Inmarsat \u2013 so as LightSquared knows well, but elects not to explain, <em>LightSquared itself earns revenue by selling satellite capacity for the very same GPS augmentation services that high precision receivers are designed to receive.\u00a0 <\/em>\u00a0LightSquared also fails to disclose that its own contracts with satellite customers reserve the right to transmit signals anywhere in the entire MSS band upon notice, so GPS receivers which use LightSquared MSS services <em>had to be designed to receive signals in the entire MSS band.\u00a0 <\/em>In other words, the \u201ddesign decision\u201d to make high precision GPS receivers that were vulnerable to interference from\u00a0 high power terrestrial interference in the MSS band <em>was imposed by LightSquared itself<\/em>.<\/p>\n<p>The fact is that LightSquared\u2019s original plans, as well as its new \u201crecommended\u201d plan, create massive interference to customers from which LightSquared has been happily collecting revenue for years.\u00a0 And LightSquared adds insult to injury by blaming GPS manufacturers for designing high precision GPS receivers in a way that allowed their customers to pay money to LightSquared.<\/p>\n<p>The proven potential for interference to high precision GPS receivers that use MSS based augmentation services, interference which LightSquared acknowledges, also raises fundamental questions about LightSquared\u2019s business practices: If it knew since 2001 that it was planning a service that was incompatible with GPS augmentation services, what did it do to disclose this fact to customers?\u00a0 Has it disclosed this fact to customers recently based on its current plans?\u00a0 Based on all reports from the affected users, the answers are \u201cnothing\u201d and \u201cno.\u201d<\/p>\n<p>The suggestion that design decisions by commercial GPS manufacturers created the interference problem through \u201cbad\u201d design decisions is also belied by the fact that many GPS receivers that LightSquared will interfere with are designed according to the demanding specifications of the Department of Defense or in accordance with the exacting standards applicable to national and international aviation navigation imposed by the Federal Aviation Administration, the International Civil Aviation Organization, International Telecommunication Union<strong> <\/strong>and other industry standards bodies. Further, integrated L-band MSS-GPS equipment has for many years been built to International Maritime Organization standards for Global Maritime Distress and Safety Systems (GMDSS). Such equipment was shown to suffer devastating interference during government tests at White Sands Missile Range.<\/p>\n<p>&nbsp;<\/p>\n<p>Either LightSquared failed to do the most minimal due diligence on GPS receiver standards, or it has conveniently ignored them.\u00a0 Either way, LightSquared\u2019s current opinions on what is \u201cgood\u201d GPS design are entirely self-serving and baseless.<\/p>\n<p><strong>Statement 4:\u00a0\u00a0 The Recommendation Document states that the \u201ccommercial GPS industry\u201d knew of LightSquared\u2019s plans and acquiesced in them.<\/strong><\/p>\n<p>\u201cSince 2003, the commercial GPS device industry has not only known about plans to develop a terrestrial wireless network in L-band spectrum, it actually approved those plans.\u201d\u00a0 RD, pgs. 6-7<\/p>\n<p><strong>The Facts:\u00a0 <\/strong>This claim merely recycles a simplistic view, endlessly repeated in LightSquared sound bites, about the history of the FCC\u2019s \u201cancillary terrestrial component\u201d rules, and also glosses over the inconvenient fact that LightSquared required a waiver of the FCC\u2019s rules, which was granted in January 2011, to proceed with its plans.\u00a0\u00a0 Simple repetition does not make the claim any more accurate.<\/p>\n<p>But the claim is lacking even in basic logic. If LightSquared knew beginning in 2001 that it was going to build the nationwide network it is now proposing, and was so intimately involved in FCC proceedings defining interference standards for MSS and GPS, how is it that between 2001 and the present, the \u201ccommercial GPS industry\u201d built and sold <em>500 million GPS receivers <\/em>that did not meet purported FCC standards, and that were incompatible with its carefully conceived plans, without LightSquared ever noticing this \u201cfact\u201d? \u00a0Hundreds of millions of these same receivers had been sold to the public by the time Harbinger bought LightSquared in 2010.\u00a0 Did Harbinger know when it invested further \u201cbillions\u201d in its satellite and network that there were so many non-compliant GPS receivers in the hands of customers and businesses, and elect to move forward anyway, without addressing this proactively with the FCC?\u00a0 And if it didn\u2019t know, why not?\u00a0 As a sophisticated New York hedge fund with billions of dollars of investors capital at its command, it should be expected to do basic due diligence. Or was the massive detrimental effect on GPS users from LightSquared\u2019s initial plans simply \u201csomeone else\u2019s problem\u201d that could be safely ignored?<\/p>\n<p>In short, even if LightSquared\u2019s account of history were true, if anyone \u201cslept on their rights\u201d it was LightSquared, and not the \u201ccommercial GPS industry.\u201d The GPS industry has done what real innovators do \u2013 build great products that tens of millions of people and businesses want to buy and put to an incredible variety of cutting edge uses.\u00a0 LightSquared, on the other hand, has not yet provided broadband services to a single customer.<\/p>\n<p>But the more basic truth is that LightSquared\u2019s version of history is simply groundless.\u00a0 The Coalition to save Our GPS has already debunked this revisionist history in detail.\u00a0 <em>Viewable at:<\/em> <a href=\"http:\/\/www.saveourgps.org\/studies-reports.aspx#letters\">http:\/\/www.saveourgps.org\/studies-reports.aspx#letters<\/a><\/p>\n<p>One final point deserves emphasis.\u00a0 There is simply no escaping the fact that it is and was <em>the FCC\u2019s responsibility <\/em>to identify and proactively address GPS interference issues to protect the substantial investment the federal government has in GPS.<em>\u00a0 <\/em>The FCC expressly committed to do this in 2005, in a passage that bears quotation at length:<\/p>\n<p><em>While we agree with the GPS Industry Council, NTIA, and other government agencies that it is essential to ensure that GPS does not suffer harmful interference,<\/em> it is also important to ensure that new technologies are not unnecessarily constrained. In this regard, we recognize that the President&#8217;s new national policy for space-based positioning, navigation, and timing (PNT) directs the Secretary of Commerce to protect the radio frequency spectrum used by GPS and its augmentations through appropriate domestic and international spectrum management regulatory practices\u2026\u00a0 Furthermore, the President&#8217;s PNT policy calls for the establishment of an inter-agency Executive Committee, on which the Chairman of the FCC will be invited to participate as a liaison, and a National Space-Based PNT Coordination Office. <em>It is our intention to establish discussions with other agencies, through the PNT Executive Committee and Coordination Office as appropriate, to better understand what protection levels for GPS are warranted.<\/em> The results of those discussions may lead to future rulemaking proposals <em>in order to ensure that all FCC services provide adequate protection to GPS<\/em>, and produce a more complete record upon which to establish final GPS protection limits for MSS ATC licensees.<a title=\"\" href=\"#_ftn2\">[2]<\/a><\/p>\n<p>Ironically, this is this same PNT that has objected strenuously to LightSquared\u2019s plans after reviewing the results of government interference tests.\u00a0 It does not appear that the FCC has taken steps to implement this commitment, nor has LightSquared supported the FCC by submitting complete and accurate disclosures of interference potential from its proposed operations at any point during this process.\u00a0 If, for whatever reason, the FCC has failed to fulfill this responsibility to date, LightSquared should not be allowed to make the \u201ccommercial GPS industry\u201d the scapegoat.<\/p>\n<p><strong>Statement 5: LightSquared claims that by limiting its operations to the Lower MSS band, it will eliminate interference to more than 99 percent of GPS receivers.\u00a0\u00a0 <\/strong><\/p>\n<p>[T]ransmissions in the 10 MHz band at the bottom of LightSquared downlink frequencies 3 \u2014 the band farthest away from the GPS frequencies \u2014 will not adversely affect the performance of over 99 percent of GPS receivers. Exceptions are mostly limited to those precision measurement devices used largely in agriculture, mining and construction. . .\u00a0 RD p. 2<\/p>\n<p><strong>The Facts:\u00a0 <\/strong>LightSquared has cited absolutely no data from the working group study or elsewhere to support this claim and the 99 percent figure is found nowhere in the Technical Working Group\u2019s final report. The available data show that this claim is blatantly false. As best one can tell from LightSquared\u2019s public statements, the claim appears to be based on the assertion that Lower band operations will not affect mass market GPS devices such as personal navigation devices or cell phones. But this is not at all what the working group data show.<\/p>\n<p>The technical working group report of the General Navigation sub-group, which studied mass market personal navigation devices, stated that \u201clab testing revealed that many devices suffered from harmful interference from the lower 10 MHz channel; specifically, 20 out of 29 devices experienced harmful interference.\u201d TWG Final Report at pgs. 16, 177.\u00a0 Similarly, data from the cellular sub-group report clearly shows that 6 out of the 39, or 15 percent, of cellphone GPS receivers tested failed the defined interference tests.\u00a0 TWG Final Report Figure 3.2.2.<\/p>\n<p>Simply counting a percentage of affected devices also ignores the true costs and benefits of interference from LightSquared\u2019s new plan. While precision receivers account for a relatively small percentage of GPS receivers, they account for enormous economic benefits.\u00a0 A recently released economic study demonstrated that high precision receivers used in construction, agriculture and survey and mapping accounted for $10 billion in private investment in GPS equipment over the last five years, and produced $30 billion in economic benefits per year. It\u2019s highly irresponsible for LightSquared to so lightly dismiss tens of billions of dollars of potential damage to the economy.<\/p>\n<p><strong>Statement 6: LightSquared claims that the use of inexpensive filters would prevent GPS receivers from \u201clistening\u201d to LightSquared\u2019s frequencies and would solve the interference problem.<\/strong><\/p>\n<p>\u201cDespite the commercial GPS device industry\u2019s best efforts to rewrite the record and obfuscate the nature of the problem, the simple fact remains that GPS receivers do not adequately reject base station transmissions in the adjacent band.\u2019\u201d RD p. 17<\/p>\n<p>\u201c[B]y failing to deploy receivers with sufficient filters, the GPS industry essentially uses LightSquared\u2019s L-Band spectrum even though it is beyond the spectrum allocated to GPS.\u201d\u00a0\u00a0 RD p.19<\/p>\n<p><strong>The Facts:\u00a0 <\/strong>Aside from integrated MSS-GPS equipment designed to use L-band satellite communications, the idea that GPS receivers are \u201cusing\u201d LightSquared\u2019s spectrum is nothing more than a sound bite, with no basis in any established or generally accepted concepts of spectrum usage or radio frequency engineering. To be able to receive faint satellite signals, GPS receivers must be designed to be highly sensitive.\u00a0 GPS receivers incorporate filters that reject transmissions in adjacent bands that are hundreds of millions times more powerful than the signals that are transmitted within the band they are designed to receive.<\/p>\n<p>LightSquared, however, is proposing to transmit signals in the band adjacent to GPS that are <em>billions<\/em> of times more powerful than GPS satellite signals. In fact, the highest recorded power levels at the Las Vegas tests conducted in the study were a staggering <em>800 billion times<\/em> the power of GPS signals. There has never been, nor will there ever be, a filter that can block out signals in an immediately adjacent frequency band that are so much more powerful, nor has LightSquared put forward any credible, independent expert opinion or other evidence that this is possible.<\/p>\n<p>The FCC mandated that the technical working group consider possible ways to \u201cmitigate\u201d interference.\u00a0 As the technical working group report confirms \u2013 its sound bites about filters notwithstanding \u2013 the only device LightSquared produced for testing was an antenna with filters so extreme that they would filter out more than 95 percent of the GPS signals as well, with an extremely severe penalty to receiver performance. Other than that, LightSquared did not produce a single filter for testing, only PowerPoint presentations and conceptual vendor proposals.\u00a0 Even these theoretical filters did not address the insurmountable technical problem presented by extremely high powered signals immediately adjacent to GPS.<\/p>\n<p>If LightSquared\u2019s theoretical filters ever made it off of the drawing board, they would force GPS receivers to retreat into only a tiny portion of the legitimate GPS band and would render useless millions of GPS devices and billions of dollars of investment by government, industry and consumers.<\/p>\n<p>And even real filters are not a solution for the 500 million receivers in use in the United States.\u00a0 The entire population of GPS users would require a minimum of 15 years to prepare for such a change. For example, factory GPS systems installed in automobiles are typically not replaced for the 10-15 years life of the vehicle and the same can be said for aircraft, trucks, ambulances, agricultural and construction machinery to name but a few. The idea of effecting such a transition in a matter of months is absurd.<\/p>\n<p>While the nation needs more wireless broadband services, there are many places in the radio spectrum already identified or allocated to 4G cellular uses, where interference to adjacent space based communications such as GPS would not occur. The satellite component of LightSquared\u2019s network \u2013 serving rural and public safety users outside of cellular coverage \u2013 is fully compatible with the adjacent uses and is already in use. To allow a new unproven use for fewer users to diminish a long-established, highly productive spectrum use for the majority is not in the public interest and must not be allowed.<\/p>\n<div><br clear=\"all\" \/><\/p>\n<hr align=\"left\" size=\"1\" width=\"33%\" \/>\n<div>\n<p><a title=\"\" href=\"#_ftnref1\">[1]<\/a> \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 Under LightSquared\u2019s new proposal, it will initially deploy using the 10 MHz in the lower MSS band.\u00a0 The need for 20 MHz is derived from the need in wireless networks to have equal amounts of paired uplink and downlink spectrum.\u00a0 The 10 MHz lower band presents 10MHz of downlink spectrum.<\/p>\n<\/div>\n<div>\n<p><a title=\"\" href=\"#_ftnref2\">[2]<\/a> \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 <em>Flexibility for Delivery of Communications by Mobile Satellite Service Providers in the 2 GHz<\/em><\/p>\n<p><em>Band, the L-Band, and the 1.6\/2.4 GHz Bands<\/em>, Memorandum Opinion and Order and Second Order on<\/p>\n<p>Reconsideration, 20 FCC Rcd 4616, \u00b6 70 (2005).<\/p>\n<p>&nbsp;<\/p>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>On June 30, 2011, the Federal Communications Commission (FCC)-mandated Technical Working Group filed a 1,000-plus page report analyzing interference from LightSquared\u2019s proposed deployment plans in the Mobile Satellite Service (MSS) band adjacent to the Global Positioning System (GPS).

The utter failure of LightSquared\u2019s initial deployment plans to pass interference tests raises fundamental questions about the representations LightSquared made to the FCC prior to its January 2011 decision that convinced the FCC to grant the waiver and convene the interference study process in the first place, and raises significant questions about the credibility of LightSquared\u2019s various claims and whether they hold up to scrutiny.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"bgseo_title":"","bgseo_description":"","bgseo_robots_index":"","bgseo_robots_follow":"","_crdt_document":"","jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":false,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[12,13,5],"tags":[],"class_list":["post-454","post","type-post","status-publish","format-standard","hentry","category-history","category-technology","category-surveying"],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"","jetpack_shortlink":"https:\/\/wp.me\/p1DORt-7k","jetpack_sharing_enabled":true,"jetpack_likes_enabled":true,"jetpack-related-posts":[],"_links":{"self":[{"href":"https:\/\/www.gpsman.com\/blog\/wp-json\/wp\/v2\/posts\/454","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.gpsman.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.gpsman.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.gpsman.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.gpsman.com\/blog\/wp-json\/wp\/v2\/comments?post=454"}],"version-history":[{"count":3,"href":"https:\/\/www.gpsman.com\/blog\/wp-json\/wp\/v2\/posts\/454\/revisions"}],"predecessor-version":[{"id":456,"href":"https:\/\/www.gpsman.com\/blog\/wp-json\/wp\/v2\/posts\/454\/revisions\/456"}],"wp:attachment":[{"href":"https:\/\/www.gpsman.com\/blog\/wp-json\/wp\/v2\/media?parent=454"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.gpsman.com\/blog\/wp-json\/wp\/v2\/categories?post=454"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.gpsman.com\/blog\/wp-json\/wp\/v2\/tags?post=454"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
