  • US DOJ moves to dismiss Ligado lawsuit

    US DOJ moves to dismiss Ligado lawsuit

    The United States Department of Justice (DOJ) has filed to dismiss satellite communications firm Ligado Network’s October 2023 lawsuit against the federal government, arguing that the court does not have jurisdiction and the company’s claims have no legal basis.

    Ligado’s $40 billion suit alleged that officials at the U.S. Department of Defense (DOD) took “unlawful actions” to, in effect, improperly seize the firm’s L-band spectrum without compensation. Ligado was granted to build a 5G communications network by the Federal Communications Commission (FCC) in 2020.

    Ligado plans to use the L-band spectrum — normally used by satellites — to develop a wireless cell phone network. However, the DoD, and several other federal agencies, including the Department of Transportation (DOT), have expressed concerns that Ligado’s terrestrial operations could have harmful effects on GPS.

    According to Ligado, as long as the DOD continues to use the spectrum, Ligado will be unable to use it to launch its terrestrial communications services.

    The DOJ’s motion asserts that rather than the U.S. Federal Claims Court, the issue instead falls under the jurisdiction of the Federal Communications Act, which “established a comprehensive remedial scheme” for FCC licensing decisions.

    Secondly, the motion says Ligado’s complaint “fails to allege any authorized government actions that could give rise to takings liability, and instead, it contends that the government has been engaged in an unlawful effort to preclude Ligado from using its FCC license. These contentions necessarily preclude any takings liability.”

    The motion goes on to contest each of the Ligado suit’s four specific legal claims. The DOJ alleges, “Ligado fails to plead any plausible facts to support its purely speculative claim that the government has occupied its licensed spectrum. And its theory that the government required a spectrum ‘dead zone’ around the separate spectrum bands allocated for GPS use similarly fails because Ligado cannot identify any authorized government action that precluded it from actually using its modified license.”

    In response to the motion, Ligado provided a statement to Breaking Defense, reiterating its complaint that government officials deliberately deprived Ligado of its rightfully licensed property and must be held accountable.

    “This attack on an American business by the world’s most powerful institution is contrary to the rule of law and antithetical to the government’s years-long support for the deployment of 5G technology as a vital national priority,” the statement said. “We worked diligently and in good faith with government agencies to find a fair resolution but were left with no choice but to pursue litigation to defend our interests. We continue to stand firmly behind our complaint and will reply to the government’s motion in the appropriate forum.”

    Georgia officials are asking the public for help in spotting non-native blue land crabs as they appear to be moving north in recent years, according to data collected by the United States Geological Survey (USGS). According to USGS, it is unclear whether this movement is driven by humans or by the crabs themselves, or if the crabs are breeding in their non-native homes. Officials worry about the damage caused by the crabs’ burrowing behavior. While scientists learn about how the species interacts with its new environment, several states are asking residents to report sightings.

UAVs have dropped weapons such as pistols and Chinese-made assault rifles, as well as consignments of opium and heroin believed to be from Afghanistan.

  • GPS OCX delays continue

    GPS OCX delays continue

    New GPS ground stations that are contracted by Raytheon Technologies to replace the current ground stations have been delayed until July 2025, the Pentagon’s testing office reported.

    The Next Generation Operational Control System (OCX) is facing a new delay of 16 months, according to the 2023 Annual Report of the Director of Operational Test & Evaluation (DOT&E).

    More than seven years behind schedule, the continuous delays have caused the U.S. Department of Defense (DOD) to go over its yearly budget and have sparked discussions as to future budget allocations for the U.S. Space Force (USSF) to continue to control and enhance the GPS constellation.

    “These delays increase the risk that U.S. and allied warfighters will be unable to conduct successful operations in future contested environments due to the lack of access to modernized GPS position, navigation, and timing (PNT) information,” the Pentagon’s testing office said in a statement.

    The M-Code can now be broadcast on 21 of the 31 GPS satellites in orbit. However, it is only available to a small number of military personnel due to both the OCX issue and a lack of radios and receivers equipped to access it.

    The Space Force has a Military GPS User Equipment (MGUE) program underway to develop new computer chip-carrying cards to retrofit existing platforms, such as aircraft and ships, so they can ingest M-code signals, as well as to develop a new handheld receiver. This effort has also experienced delays, according to a June 2023 report by the Government Accountability Office.

    The 2024 DOT&E report notes that because of the delays in the development of the MGUE receiver cards, the Army and Marine Corps are now buying commercially developed receivers capable of ingesting the M-Code for fielding with ground vehicles.

    Additionally, the DOT&E report cautions that because the OCX software is designed to be the basis for an upgraded system, OCX Block 3F, designed to control the planned next generation of GPS satellites called GPS IIIF, that effort also is likely to be delayed. The Space Force intends to launch the first GPS IIIF satellite in 2027.

  • Intecs combines GNSS and sensor data for train localization

    Intecs, a hardware and software developer, is creating a multi-sensor, GNSS-based platform for obtaining absolute position of trains on rail lines. The system incorporates cameras that read QR codes installed in the area adjacent to the track. The system includes a robust, software-based, data fusion engine that combines GNSS and visual data to determine train position.

    The delay when a train loses its position can be significant and affect other vehicles on the rail lines. The Intecs system — assisted GNSS with imaging sensors for rail applications (AGIS4RAIL) — can correctly identify the position of a vehicle.

    Test campaign
    Numerous field tests have been conducted for the new system. One of the most critical sets of trials was carried out on an auto racing track. The trial involved a ground vehicle with GNSS antennas positioned on the roof and with cameras pointing to the side where QR code panels were set up at 10 m intervals. The vehicle was driven for 30 laps around the course under various conditions. AGIS4RAIL correctly identified the position of the vehicle at every lap, with the vehicle achieving a maximum speed of 35 km/h. The maximum estimated error was 4.76 m, which is in line with the target of 5 m.

    Imaging sensors help to reduce the negative impact of various local effects on positioning systems that rely solely on Global Navigation Satellite Systems (GNSS), such as multipath errors. The AGIS4RAIL system also offers protection against jamming and spoofing. Additionally, the QR-code landmarks can contain data to verify the authenticity of the landmark itself.

    Further testing continues and will soon include trials onboard operational trains in Italy, according to Intecs. The AGIS4RAIL project received funding under the European Space Agency’s Navigation Innovation and Support Program (NAVISP).

  • Questions that urgently need answers

    Questions that urgently need answers

    The Department of Defense (DOD) shoulders an enormous responsibility, perhaps one whose significance the world does not fully grasp: the sheer number of military, civil and commercial users, each with hundreds of unique use cases, that depend on the Global Positioning System (GPS).

    No other DOD-operated system serves such a diverse array of users and interests. From Special Operators to ship and tank drivers, pilots and operators, the military user base is expansive. Civil users include first responders, general aviators, and those supporting the international flying public, whose numbers are again setting records. Additionally, countless average people like you and me just “use it” in our daily lives without considering how it works. The ever-expanding commercial market consists of $1.7 trillion in 2023 dollars in economic benefits accruing to the U.S. economy alone, millions of jobs, and fierce global competition to produce the “best of the best” of the 6.5 billion user receivers in operation today.

    With these users and interests in mind, what does that mean for GPS’ future? It raises more questions than answers — about policy, governance, program execution and threats that urgently need to be addressed:

    • What indicators will determine whether the United States has met its policy goal to be the global leader in “service provision and the responsible use of global satellite navigation systems, including GPS and foreign systems?”
    • Building on this publication’s previous articles, what constitutes a “Gold Standard” in 2024? Which users determine this definition? How and when do foreign global navigation satellite systems’ capabilities factor into this definition?
    • What funding levels ensure the security, accuracy, availability and resilience of GPS? In Fiscal Year 2022, Congress provided more than $2 billion for DOD to procure and conduct research and development on GPS III and IIIF satellites, procure military user equipment, and upgrade the ground architecture. In 2022, the Department of Transportation received $22 million for GPS resiliency and $92 million for the Wide Area Augmentation System. Is this level of funding sufficient to bring innovative technologies to GPS?
    • Speaking of innovation, U.S. law directs DOD to “sustain and operate” GPS for military and civilian purposes. How can innovative GPS technologies contribute to “sustain and operate” missions?
    • Who should participate in decisions regarding the timing of GPS upgrades and satellite launches?
    • Where does the most accurate data on cyber and other threats to GPS satellites, ground stations, military and civil user equipment, and commercial receivers reside? Who evaluates that data to determine the overall risks to GPS? Should those risks be shared with all users? How quickly will the most severe risks be mitigated?
    • Do the Federal Communications Commission, the Department of Homeland Security, and the Department of State have sufficient resources to detect and prosecute illegal and irresponsible spoofing and jamming incidents in the United States and overseas?
    • What is the earliest date the much-anticipated L1C, L2C, and L5 signals can be operational?

    The GPS Innovation Alliance (GPSIA) believes the U.S. government does not have to shoulder such difficult and urgent questions alone. GPSIA looks forward to sharing insights while working with government agencies and the wider user community to answer these questions and put in place executable plans to address these challenges.
