US Army approves production of vehicle-mounted GPS alternative
The Mounted Assured, Positioning, Navigation and Timing System, or MAPS, is a key element of the service's modernization push. The Army established a cross-functional team through Army Futures Command in 2017 to advance capabilities, both mounted and dismounted, that would help the Army operate in environments where the enemy might jam its space-based GPS systems used for navigation.
As those efforts progressed in development, they were transferred to the Program Executive Office Intelligence, Electronic Warfare and Sensors to be managed as programs of record.
'This monumental achievement is the culmination of over six years of hard work and dedication by [Program Manager] PNT and Mounted PNT,' Lt. Col. Damian Dixon, the Army's Mounted PNT product manager, said in the statement.
The MAPS Generation II capability 'provides GPS anti-spoofing and anti-jamming capability through sensor fusion algorithms and non-radio frequency sensors to distribute positioning, navigation, and timing data so mounted soldiers can operate in environments where military GPS is denied or degraded,' the statement notes.
In addition to enabling forces to communicate, move and shoot, the system distributes PNT data 'to multiple clients on a single platform, eliminating redundant GPS receivers and antennas,' according to the statement.
The MAPS GEN II system consists of an internally mounted navigation hub where data coming from sensors and receivers are fused together and an anti-jam antenna system mounted to the outside of the vehicle.
To date, the Army has spent roughly $500 million in procurement funding for the mounted PNT program as it previously fielded a first-generation capability to rapidly deliver an initial capability to the battlefield, according to fiscal 2025 service budget documents.
The Army plans to procure 619 MAPS GEN II systems for a total of $130 million in fiscal 2025, according to budget documents. This includes spares, follow-on test and evaluation, logistics support and engineering changes for Armored, Stryker and Infantry Brigade Combat Teams, the documents show.

Why the US military wants troops to be able to fix their own stuff
Troops often find themselves surrounded by gear they cannot legally fix. A bipartisan push is trying to allow troops to turn to their own wrenches to repair military equipment rather than relying on civilian contractors. Service members are allowed to fix a lot of military equipment on their own, with many troops specializing in mechanical repair for guns, aircraft, and even weapons optics. But some equipment contracts come with strict provisions that stipulate that repairs can only be performed by contractors and limit the technical data and intellectual property that can be shared with troops for repairs. Some lawmakers say these stipulations are problematic for troops in need of urgent repairs and take advantage of DoD funding. "When you're deployed in the field and you have a mission to complete and you have people's lives to protect, it just doesn't make sense to be constrained by some commercial agreement that you have with the manufacturers," said Greg Williams, the director of the Center for Defense Information at the Project on Government Oversight. Now, a bipartisan push from senators Elizabeth Warren, a Massachusetts Democrat, and Tim Sheehy, a Montana Republican, is calling for a change amid new movement on the National Defense Authorization Act. These lawmakers highlight instances of the Navy ferrying contractors to sea for simple fixes, Marines in Japan forced to send engines to the US for repair instead of repair on site, and one contractor that "charged $900 a page for upgrades to its maintenance manuals for an Air Force aircraft." These moves mark the latest in a string of actions to overcome right-to-repair barriers. A 2023 California bill, for example, spurred Apple to endorse the ability for consumers to repair and modify their own devices. Medical device manufacturers came under fire during the pandemic for troublesome restrictions on ventilator repair. And US farmers have criticized farming equipment manufacturer John Deere, now embroiled in a federal lawsuit, for what they see as prohibitively restrictive controls on repair part access and burdensome diagnostics tech tools. President Donald Trump's tariffs could strengthen the right-to-repair movement throughout the nation, as some consumers grow increasingly reluctant to toss out high-priced goods that are damaged and seek to repair them instead. Top Pentagon brass have pushed for comprehensive changes to repair policies since January. Amid major transformation initiatives within the Army, Secretary of the Army Daniel Driscoll and Secretary of Defense Pete Hegseth have each called for the inclusion of right-to-repair provisions in all new and existing Army contracts. Navy Secretary John Phelan told lawmakers in June that when visiting the aircraft carrier USS Gerald R. Ford, he discovered six of the ship's eight ovens, essential tools required to feed thousands of sailors, were out for repair, adding that crewmembers aboard the vessel were legally prohibited from performing repairs. "It is crazy. We should be able to fix this," he said. Such high-level advocacy comes as other military leaders have observed that future warfare will require more innovative fixes from troops on the front lines. "The force of the future will fix on the spot," Chairman of the Joint Chiefs of Staff Gen. Dan Caine said during a congressional hearing on military spending last month. The Iraq and Afghanistan wars saw robust base build-ups for troops, where equipment could be sent for intensive maintenance needs with the near-assurance of US air supremacy. Such guarantees are almost certainly a thing of the past, experts say, at least for high-end fights. Right now, "it all comes down to the particulars of the contract involved," Williams explained. "Different contractors have arrived at different arrangements with the Defense Department about when they have a chokehold on repairs and when they don't." "And so it needs to be negotiated on a contract-by-contract basis," he said. Williams pointed to a near-miss naval incident and subsequent relief of USS John McCain's captain as a clear example of what can happen when repairs go unaddressed. The destroyer nearly collided with another vessel during a refueling operation when the ship's lingering steering problems arose unexpectedly. It's unclear whether the right to repair would have prevented that outcome, but the argument for it is that it eliminates the unnecessary tension that exists today. As things stand now, Williams said, "it comes down to a push and pull between the manufacturer and the consumer."

University of Colorado Boulder's Quantum Forge Students Complete Program with Xairos
LAFAYETTE, Colo.--(BUSINESS WIRE)--Xairos Systems, Inc., a quantum technology company that is developing a global resilient timing architecture to augment timing from GPS (Global Positioning System), benefitted from hosting four quantum physics and engineering physics undergraduate students in the lab, where they were exposed to the real-world problem of entangling photons, quantifying the interaction, and visualizing the invisible process. Four undergraduate students from University of Colorado's Quantum Forge program successfully completed the program, hosted by Xairos, where they gained real-world experience with photon entanglement in the Xairos quantum lab. Quantum Forge is a program at the University of Colorado Boulder that gives students first-hand experience with the quantum industry through sponsored projects with industry partners. Students gain proficiency with industry techniques while becoming more familiar with company culture and norms, positioning them well for industry entry upon completion of the course. Students can apply for Quantum Forge in March for the upcoming academic year. The participating students included four seniors majoring in physics and engineering physics: Conor O'Neill, Grayson Hallmark, Ethan Trapp and Andrew Nguyen, all of whom completed the program in Spring 2025. 'Working with Xairos was an incredible experience because I got to see start-up culture and be involved in a project applying quantum optics,' said Nguyen. 'It's rewarding to see physics from the classroom being used in the real world.' Xairos is developing a global resilient space-based timing architecture using Quantum Time Transfer. Accurate timing synchronization is critical for improving the efficiency of power grids, networks and data centers, including those needing higher compute capabilities due to rising demand from Artificial Intelligence. Accurate and resilient timing is also foundational for location data, including GPS. "Most capstone experiences for science majors are designed for students continuing on to graduate study,' said Michael Bennett, the course designer and Director of Education for the Q-SEnSE NSF Quantum Leap Challenge Institute at CU Boulder. 'But the reality is that companies are increasingly looking to hire at a variety of levels of quantum specialization. The Xairos team is a great example of how even bachelors-level workers can make meaningful contributions to the quantum workforce.' 'We have been very impressed by the students' determination and motivation,' said David Mitlyng, CEO of Xairos. 'Achieving photon entanglement is not for the faint of heart, and these young professionals showed fortitude and commitment.' About Xairos Xairos is developing a global resilient space-based timing architecture using Quantum Time Transfer (QTT), a protocol invented, patented, and perfected by the Xairos team. Accurate timing synchronization is critical for the world's transportation, networks, financial transactions, data centers, and power grids. Xairos is commercializing QTT to develop the next generation of Position, Navigation and Timing (PNT), with sub-nanosecond-level accuracy (1000 times better) and the security needed for future networks and applications.

Senator to introduce a bill requiring Army helicopters to fly with key flight tracking technology turned on
The top US senator overseeing aviation says he will introduce a bill that 'will close the regulatory loophole' that allowed an Army Black Hawk helicopter to operate with key flight tracking technology, called ADS-B out, turned off the night it collided with an airliner near Washington, DC. Sen. Ted Cruz, ranking chairman of the Senate Committee on Commerce, Science, and Transportation, made the announcement Tuesday at an aviation industry summit only miles from Ronald Reagan Washington National Airport where the January 29 crash killed 67 people. Cruz has been sharply critical of Army practices since the crash, which he said was given too much leeway by the Federal Aviation Administration to operate with the flight tracking technology equipment, called ADS-B out turned off. The technology broadcasts the location of a moving aircraft to other planes nearby and can update much faster than traditional radar. Cruz said his Rotorcraft Operations Transparency and Oversight Reform bill, or ROTOR Act, will also 'review helicopter routes at airports across the country' and will require the Army inspector general to 'review systemic breakdowns that may have contributed to the crash.' Later this month, the National Transportation Safety Board will hold a three-day investigative hearing on the crash.
