“Ligado’s planned usage will likely harm military capabilities, particularly for the U.S. Space Force, and have major impact on the national economy,” two ranking Senators and a Representative wrote. The timing could not be worse, they said to allow what “is fundamentally a bad deal for America’s national and economic security.”

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.

“I’ve been a revolutionist for 47 years,” Brad Parkinson began a recent invited lecture at Google, “with this stealthy revolution. GPS is indeed a stealthy revolution.” In his lecture “GPS and Humanity” he described how GPS has “stealthily” crept into the fabric of global society and created dependencies that did not exist before.

The chairman of the Federal Communications Commission (FCC) told two U.S. Senators in January that his agency could not complete a decision on Ligado Network’s license modification by the end of 2019 because of a late-in-the-year response from a key federal agency.

In a letter made public late Friday, the point person for all federal agency use of frequencies told commercial spectrum regulators his agency could not support approval of Ligado Networks’ request to use satellite frequencies for a terrestrial wireless network.

The Defense Department urged spectrum regulators this week to reject a proposal by Virginia-based Ligado Networks to build a wireless terrestrial communication system that could, it said, interfere with GPS.

The grapevine was abuzz on Halloween with chatter that the Federal Communications Commission (FCC) might soon act on a long-pending request from Ligado Networks to use spectrum near the GPS frequencies to support terrestrial communications.

Ligado Networks is pushing spectrum regulators to make a decision on its request to allow satellite frequencies near the GPS band to also be used for terrestrial 5G networks.

A judge has discontinued a $2 billion lawsuit alleging “massive fraud” in a deal that helped launch a proposed project GPS experts oppose as a threat to satellite navigation receivers.

The $2 billion lawsuit filed by Harbinger Capital Partners against Apollo Global Management over whether Apollo knew about GPS interference issues has been stayed yet again—again at the request of Ligado Networks, the current holder of the frequencies involved.

As part of the development of a National Spectrum Strategy, the U.S. Department of Agriculture (USDA) is asking for feedback on future spectrum needs in rural America and, more importantly for the GNSS community, on what spectrum needs to be protected.

A dozen geospatial organizationswith a total of more than 170,000 members have registered their opposition to plans by Ligado Networks to use frequencies neighboring the satellite navigation band for terrestrial services.

The $2 billion spectrum-related lawsuit filed by Harbinger Capital Partners against Apollo Global Management has been stayed once again — this time at the request of Ligado Networks, the current holder of the frequencies involved.

Though 2019 is brand new there are a host of GPS-related issues carrying over from 2018. This is one in a series of stories on satellite navigation issues on the table as the new year gets underway.
Virginia-based Ligado Networks and its predecessor firm LightSquared have been pushing since 2011 to change the rules governing how its spectrum can be used — a move essential to building a ground-based communications network that navigation experts insist will interfere with GPS receivers.

UPDATED: The Federal Communications Commission (FCC) on Nov. 15 unanimously approved waivers allowing the use of the Galileo E1 and E5 signals for non-federal purposes in the U.S. and denied the E6 signal waiver request. Approving the E6 waiver “could constrain our future spectrum management for non-Federal operations in the U.S.” the FCC wrote in the draft order document released ahead of the meeting.
