Thirteen agencies responsible for much if not most of the nation’s military, civil, security and economic activity say Ligado Networks’ plan to use satellite frequencies for 5G communications would interfere with GPS users in general and DOD use in particular.

The chairman of the House Committee on Transportation and Infrastructure has teamed up with the chairman of the House Armed Services readiness subcommittee to demand answers from the Federal Communications Commission on whether reallocating a band of spectrum will damage the Global Positioning System, or GPS, as the Pentagon claims.
Apr 16, 2020
The Federal Communications Commission is poised to approve a draft order as soon as today that would reallocate a specific portion of the radio spectrum for broadband communications, overruling a decade of strong objections from the Department of Defense.

Ligado’s terrestrial broadband service plans are perhaps “the greatest current threat” to the position, navigation and timing universe, PNTAdvisory Board Vice Chairman Bradford Parkinson wrote Tuesday for GPS World…

It seems unrealistic that Ligado can or will reliably guarantee that these widespread installations will be continually adjusted and monitored to avoid GPS interference. I believe the concept of allowing the installation of transmitting towers that, by design, will interfere with normal GPS use at some distance away opens the door to tacit approval of short-range (or not-so-short-range) GPS jammers. While I can commend the entrepreneurial spirit, the Ligado proposal seems very reckless indeed. The incremental value of an additional broadband transmitting system when there are at least five already in existence seems trivial compared to the potential damage done to the modern utility named GPS. I sincerely hope the FCC can find a spectrum swap or deny outright the current Ligado application…

Aireon, a joint venture between Iridium Communications, Nav Canada, the Irish Aviation Authority, Italian air navigation service provider Enav, and Naviair—which provides air navigation services in Denmark, Greenland, and the Faroe Islands—is on track to have a space-based ADS-B network operational in 2018. Aireon is doing this with an ADS-B receiver payload piggybacking on each of the 75 new Iridium NEXT communication satellites…

The long-running, high stakes battle between the GPS community and Ligado Networks may enter a new phase next month when the firm presents to the nation’s leading GPS experts its plan to develop a combined terrestrial/satellite network using its spectrum neighboring the GPS band…

Ligado is attempting to rewrite the rules to the detriment of GPS and a fast-growing satellite service. That’s certainly not what we voted for in 2003 and not something the FCC should allow today…

Portions of Ligado’s spectrum sits next to spectrum used for GPS systems. Private and publicly-funded studies demonstrated significant interference problems, resulting in a 2011 FCC decision to block the earlier plans of Ligado, sending its predecessor into bankruptcy. Subsequently, Ligado has granted some concessions to several larger GPS players, but numerous objections from the GPS and aviation communities, among others, remain. Interference studies continue to show significant interference problems resulting from Ligado’s current proposal…

Ensuring a reliable level of security among IoT devices and the networks they connect to needs stepped-up coordination between device makers and other sectors, widespread security standards, and increased use of common sense and already-established cybersecurity steps, Technology Policy Institute panelists said…
