  • Senate proposes $15M to develop GPS alternatives

    Senate proposes $15M to develop GPS alternatives

    This week Sen. Patrick Leahy (D-Vt.), chair of the Senate Appropriations Committee, released that body’s version of nine different appropriations bills. The accompanying report for the bill to fund the Transportation Department (DOT) outlines the Senate’s intentions and way forward for establishing alternatives to GPS.

    The report provides $15 million for the fiscal year that began on the first of October “to establish a program that leads to wide adoption of multiple technologies that provide the necessary GPS backup and complementary PNT as identified by the Department’s report.”

    The department report referenced was on a demonstration project that examined GPS backup and complementary technologies from 11 different vendors. That DOT report found, based on the technologies demonstrated, a combination of signals delivered from space, terrestrial low frequency (LF) and ultra-high frequency (UHF) broadcasts, and fiber would best meet the nation’s needs.

    The Senate report accompanying the funding bill outlines components of the GPS alternatives program, including:

    • development of safety-critical PNT requirements and standards,
    • user adoption models to facilitate responsible use of resilient PNT, and
    • procurement of services deemed appropriate by the department.

    The Senate Committee report can be found here. Relevant provisions are on page 12.

    Services Contracts

    While not setting a deadline for issuance of a Request for Proposal, the mention of procuring services is seen by many as a strong indication that Congress expects more than just additional studies.

    Services contracts, as opposed to the government building its own system, have long been advocated by numerous members of industry and by the Resilient Navigation and Timing Foundation. Contracting for services with commercial providers is a better model, they have argued, as the needed technologies are mature and commercially available. Also, issuing one or more services contracts would avoid the need for the huge funding lines and lengthy delays inherent in a government major systems acquisition.

    Many have suggested that services contracts would also be a much more economical approach for the government. They say commercial interests can operate their systems more efficiently, and that they could offer additional services to other customers, potentially reducing costs to the government.

    ADS-B Sets Example

    Such an approach was used by the Federal Aviation Administration (FAA) for the ADS-B air traffic safety and management system. The FAA needed to monitor and use signals from ADS-B equipment aboard a wide variety of aircraft flying in U.S. airspace. Rather than building a nation-wide ground infrastructure, the FAA issued a long-term service contract for a company to collect and provide the signals. The awardee, Exelis (now L3Harris), won the contract, built the infrastructure, and now provides ADS-B information to the FAA and others on a subscription basis.

    Most observers expect the portions of the Senate bill and report about the GPS alternatives program to be adopted in conference with the House and then enacted into law.

    How far the Department of Transportation will be able to develop the program this fiscal year remains to be seen. The Senate provisions do require DOT to report on its progress in a year’s time. Earlier informal reports and updates to the committee are likely to inform funding and other legislation on this effort for fiscal year 2023.

  • Congress makes moves against FCC’s Ligado decision

    Congress makes moves against FCC’s Ligado decision

    At first it was a flurry of letters and public statements from U.S. senators and members of the house. Then there was a senate hearing on the topic, and the issue was discussed in several other hearings.

    The Federal Communications Commission’s (FCC) approval of a long-standing request by Ligado Networks continues to be controversial. The request was to make terrestrial broadcasts on a frequency near that used by GPS. Broadcasts which, according to analyses by the departments of Defense and Transportation, will interfere with GPS reception for many users.

    Now it looks as though Congress is ready to move beyond talk and enact one or more pieces of legislation. These would require an independent technical review of the FCC’s decision and place limits on the ability of Ligado Networks to use the license it was granted.

    Congressional interest has been fueled both by member concerns and a regular drumbeat of input from constituents. The recently formed Keep GPS Working Coalition is just one example. It was created from a larger group of more than 70 companies and organizations across a broad swath of industries that has gone on record against the decision and has been supporting congressional action.

    National Defense Authorization Act

    A primary vehicle for congressional action looks to be the National Defense Authorization Act (NDAA) for 2021. Unlike other “annual” legislation that often gets sidetracked or delayed during election years, Congress has passed an NDAA for each of the past 59 years. As such, it is a particularly powerful tool.

    This is doubly so in this case, as the member of Congress that has been the most outspoken critic of the FCC’s decision is Senator Jim Inhofe (R-OK). He chairs the Senate Armed Services Committee that has direct responsibility for the NDAA.

    The Senate version of the NDAA has several provisions that directly address the FCC’s decision.

    Responding to conflicting claims about the findings of government and private tests, the bill requires the Defense department to contract with the National Academies of Science, Engineering and Medicine for an independent technical review.

    Evaluating Potential Impact on GPS

    Among other things, the review will compare the different methods of evaluating the potential impact on GPS services from Ligado’s transmissions, and determine which of those was the most effective in guarding against any harm.

    The bill also prohibits the Defense Secretary from spending any money to comply with the FCC’s order until the Congress has been given an estimate of the total cost to the department of coping with Ligado’s transmissions.

    While the FCC order requires Ligado to modify or replace any government receivers impacted by its operations, the Defense department and others have said this is only a small fraction of the overall costs they would incur.

    The bill requires the Defense Department estimate to consider a much larger scope of costs including:

    • To upgrade, repair, or replace potentially affected receivers
    • To modify, repair, or replace equipment, pares, associated ancillary equipment, software, facilities, operating manuals, training, or compliance with regulations, including with regard to the underlying platform or system in which a capability of the Global Positioning System is embedded; and,
    • For personnel of the department to engineer, validate, and verify that any required remediation provides the Department with the same operational capability for the affected system prior to terrestrial operation in the 1525 to 1559 megahertz or 1626.5 to 1660.5 megahertz bands of electromagnetic spectrum.

    The House version of the NDAA also provides that:

    “The Secretary of Defense may not enter into a contract, or extend or renew a contract, with an entity that engages in commercial terrestrial operations using the 1525–1559 megahertz band or the 1626.5–1660.5 megahertz band unless the Secretary has certified to the congressional defense committees that such operations do not cause harmful interference to a Global Positioning System device of the Department of Defense.”

    RETAIN GPS and Satellite Communications Act

    Senator Inhofe has also announced he will introduce stand-alone legislation when Congress returns from summer recess. His “Recognizing and Ensuring Taxpayer Access to Infrastructure Necessary for GPS and Satellite Communications Act,” or “RETAIN GPS and Satellite Communications Act,” would require Ligado to modify or replace any receiver, including those used by private citizens, that would be impacted by Ligado’s operations.

    This modification would be required before the FCC’s order allowing them to transmit could come into force. Most observers opine that the number of impacted civil receivers in the U.S. is so great that this would effectively deny Ligado use of the frequency.

    Introduction of the RETAIN GPS and Satellite Communications Act was planned for before the summer recess. Its delay until after was likely to provide more time to recruit co-sponsors.

    GPS Interference a ‘Niche’ Issue

    One observer commented that “GPS and the FCC Ligado order are really niche issues. As time goes on, more and more members of Congress will hear about it from constituents and be appalled.”

    The delay will also allow time for the mammoth NDAA bill to clear Congress. RETAIN GPS would then have more chance for the spotlight.

    Many industry observers have opined that regardless of congressional action, Ligado will struggle to find a successful 5G or other business model that will generate a significant revenue stream from the spectrum.

    As public concern continues to grow and Congress responds with legislation, it may turn out that Ligado finally won the battle at the FCC but ended up losing the war.
