The production milestone marks the close of a development arc that began at JNC 2023 in San Diego, where BAE first unveiled NavGuide as the designated successor to the Defense Advanced GPS Receiver. DAGR, which has powered both handheld and vehicle-integrated GPS for global defense forces for over two decades, used SAASM technology alongside dual-frequency encrypted signals to resist jamming and spoofing. More than 650,000 units were fielded internationally before production concluded. 

NavGuide transitions that installed base to M-Code — the military GPS signal purpose-built to defeat modern electronic warfare threats. The compact, lightweight receiver features an intuitive full-color user interface with waypoint navigation and a moving-map display for enhanced situational awareness. It also provides 9-line targeting capability, meets key military environmental requirements, and is compatible with existing FRPA and anti-jam electronic units. 

The integration story is central to the program’s value proposition. NavGuide is backwards compatible with existing DAGR installations and is designed for rapid integration into existing mounts and accessories without mission interruption — with an average installation time across more than 30 vehicle platforms of under two minutes, requiring no changes to existing cables, mounts, or vehicle software. 

NavGuide sits within a broader M-Code receiver portfolio BAE unveiled at JNC 2025 in Cincinnati. The company’s security-certified Common GPS Modules leverage the M-Code signal across a product line that scales from the world’s smallest and lowest-power M-Code GPS for SWaP-challenged applications to highly robust receivers with integrated anti-jam antenna electronics for exceptionally challenging environments. The full portfolio includes the ASR-M, DIGAR-300M, MPE-M, MicroGRAM-M, NavFire-M, NavStrike-M, NavStorm-M, and SABR-M alongside NavGuide.

BAE has delivered selective availability anti-spoofing modules to users in more than 45 countries and is now fielding M-Code GPS receivers in multiple formats for U.S. armed forces and allied nations. NavGuide is available to all U.S. service branches and to partner nations through foreign military sales. Production is based at BAE’s engineering and manufacturing facility in Cedar Rapids, Iowa. 

“NavGuide is more than just a replacement for DAGR,” said Luke Bishop, director of Navigation and Sensor Systems at BAE Systems. “Built on the same trusted foundation for easy installation and transition, it delivers a more resilient, user-friendly M-Code GPS solution. Now in production, NavGuide gives warfighters the precise positioning data and situational-awareness tools they need to stay effective in modern, contested, multi-domain operations.”

The module is designed for OEMs deploying products across regions where RTK networks, SBAS coverage, or reliable communications links are inconsistent or unavailable. Key additions over the base ZED-X20P include Galileo HAS for globally accessible PPP corrections, Moving Base functionality for relative positioning applications, and improved jamming and spoofing detection and mitigation — the latter verified at Jammertest 2025. The module retains compatibility with u-blox’s PointPerfect correction service.

Targeted applications include UAV mapping and navigation without continuous connectivity, marine operations such as dredging and seabed mapping, precision agriculture and construction in remote environments, and autonomous platforms requiring robust relative positioning. The ZED-X20P-01B maintains the established ZED form factor, offering a direct upgrade path for existing customers without hardware redesign.

“ZED-X20P-01B reflects our commitment to making high-precision positioning more scalable, resilient, and easier to deploy globally,” commented Andreas Thiel, CEO, u-blox.

Samples and evaluation kits are available in June. u-blox will demonstrate the module at XPONENTIAL 2026 in Detroit at booth 23023.

The patent covers a visual-inertial odometry approach that uses onboard cameras and inertial sensors to estimate position without GPS. When multiple drones operate together, the system shares positional data between vehicles in real time to improve individual accuracy. The architecture uses an Extended Kalman Filter for state estimation and is designed to keep flight-critical processing onboard each vehicle while minimizing inter-vehicle data exchange.

The capability addresses a persistent vulnerability in drone operations: GPS jamming and spoofing have degraded or disabled unmanned systems across multiple recent conflict zones, accelerating DoD and NATO investment in navigation solutions that do not depend on satellite signals.

The option agreement provides an evaluation period during which NorthStrive will assess the technology and engage potential partners before negotiating a definitive license.

GNSS interference is named alongside long-range weapons systems, counter-UAS, and advanced air defense technologies as risks that international law alone has proven insufficient to address.

ICAO Secretary General Juan Carlos Salazar made the assessment at the opening of the 2026 World Overflight Risk Conference in Valletta, Malta, telling delegates that emerging military capabilities are creating an environment where civilian aircraft face heightened risk of being targeted or caught in crossfire. “We must now reach beyond the boundaries of aviation as we have known it,” Salazar said.

Salazar pointed to the recent Middle East crisis as both a demonstration of the aviation industry’s adaptability and evidence of the limits of operational workarounds. More than ten states partially or fully closed their airspace during the escalation, and while ICAO’s regional contingency frameworks helped coordinate rerouting, the Secretary General characterized these measures as costly and temporary rather than solutions to the underlying security threats.

The organization is pressing states to take three immediate steps: share threat intelligence rapidly when activities pose risks to civilian aircraft, strengthen risk assessment mechanisms and decision-making timelines, and improve coordination between military and civilian authorities to prevent misidentification. ICAO is also finalizing a Global Crisis Management Framework and updating its Manual Concerning Safety Measures relating to Military Activities and its Risk Assessment Manual for Civil Aircraft Operations Over or Near Conflict Zones.

Salazar grounded the legal case in ICAO Assembly Resolution A42-4 and Article 3 bis of the Chicago Convention, which explicitly prohibits the use of weapons against civilian aircraft, while acknowledging that the framework has not kept pace with regional conflict.

This capability is increasingly critical as data centers and 5G virtualized Radio Access Networks build deeper dependencies on satellite-based timing.

The modules support automatic source selection and locking across GNSS, Synchronous Ethernet (SyncE), and Precision Time Protocol (PTP), switching between sources without disrupting timing continuity. That flexibility is central to the design intent: in infrastructure environments where timing failure cascades quickly into service degradation, the ability to transition seamlessly from GNSS to a secondary source — and hold position during that transition — is the operational requirement the module is built around.

When GNSS signal is lost, onboard Oven Controlled Crystal Oscillators maintain holdover for up to eight hours depending on variant. The MD-990-0011-BA01 provides four hours of holdover performance; the MD-990-0011-BC01 extends that to eight. Both integrate a SyncE synthesizer with dual independent Digital Phase-Locked Loop channels, a temperature sensor, EEPROM for board configuration, and a low-jitter oscillator in a single plug-in form factor.

Developed in collaboration with Intel, the modules are designed for compatibility with Intel Xeon 6 SoC-powered server platforms, supporting OEMs and ODMs building next-generation infrastructure for distributed workloads and real-time applications. Both variants are available now in production quantities through Microchip direct sales and authorized distributors.

The Defense Acquisition Executive terminated OCX on April 17 on the recommendation of the acting service acquisition executive.

OCX was designed to replace two legacy GPS ground control systems — the Architecture Evolution Plan, which currently commands the GPS satellite constellation, and the Launch, Anomaly and Disposal Operations system. At cancellation, total program cost stood at approximately $6.27 billion, encompassing Raytheon funding and government testing and support costs.

The Space Force contractually accepted OCX from Raytheon in July 2025 following multi-year factory testing, then began integrated systems testing against the broader GPS enterprise of ground systems, satellites and user equipment. That testing exposed problems across a broad range of capability areas that program officials concluded would put current GPS military and civilian capabilities at risk if the system were transitioned to operations.

“Extensive system issues arose during the integrated testing of OCX with the broader GPS enterprise,” said Mission Delta 31 Commander Col. Stephen Hobbs. “Despite repeated collaborative approaches by the entire government and contractor team, the challenges of onboarding the system in an operationally relevant timeline proved insurmountable.”

Rather than continue investment in OCX, the Space Force will pursue further incremental upgrades to AEP, which has received sustained improvement over the past decade. Program officials said that track record provides confidence that the existing control system can continue to support the GPS constellation and deliver new capabilities.

Acting Service Acquisition Executive Tom Ainsworth framed the cancellation as an acquisition reform lesson, calling for rapid, incremental capability delivery over complex all-or-nothing system development — language consistent with broader Pentagon pressure to accelerate fielding timelines across major defense programs.

The termination leaves GPS modernization dependent on a ground control architecture that predates the Block III satellite generation it was originally designed to operate. The implications for M-code expansion, anti-jam capability delivery and next-generation timing services — all of which OCX was intended to enable — will be a central question for the program’s successor effort.

Early Tuesday morning, Lockheed Martin and the U.S. Space Force launched the final satellite in the GPS III series, GPS III Space Vehicle 10 (SV10), into medium Earth orbit (MEO) aboard the Falcon 9—marking a major milestone for the industry. 

The GPS III satellite delivers “major upgrades in constellation resilience and accuracy,” according to Lockheed Martin, and includes a crosslink demonstration payload that will allow GPS satellites to directly communicate with each other in space, increasing on-orbit resiliency. This paves the way for the next-gen GPS IIIF series, which is now in production. 

GPS III SV10 launched from Cape Canaveral Space Force Station at 2:53 a.m. Eastern time on Tuesday, securing signal acquisition soon after. It is being managed at Lockheed Martin’s Denver Launch & Checkout Operations Center pending formal acceptance into the GPS operational control network.

This is the fourth consecutive GPS launch on an accelerated timeline and the seventh flight for the first stage booster supporting the mission, which previously launched six Starlink missions.

Transforming the Constellation  

GPS III satellites offer three times greater accuracy and eight times stronger anti jamming than legacy spacecraft, and provide secure M-Code signals for warfighters, according to Lockheed Martin. They’re also equipped with a demonstration Digital Rubidium Atomic Frequency Standard clock, an advanced atomic clock for reliable and precise time-keeping capabilities.

Together, these satellites “transform the constellation,” said Lisa Dyer, executive director of the GPS Innovation Alliance (GPSIA), supporting “an even better experience for the billions of users who rely on GPS every single day.”

“These signals,” she said, “help emergency responders and everyday travelers navigate more efficiently, increase the resilience of our transportation networks, ensure warfighters can operate in contested environments, and much more.”

Military users benefit from more dependable PNT in contested or hostile environments; civilian users get enhanced smartphone navigation and faster emergency response location; and financial and telecommunications markets have more precise timing.  

Looking Ahead 

The next generation of satellites, the advanced GPS IIIF, will bring strong anti-jamming capabilities for warfighters and significant improvements for civilian users. Deploying these “next‑generation spacecraft is essential for preserving reliable global coverage, and the IIIF block will add a new suite of capabilities that further harden the constellation’s resilience,” according to Lockheed Martin.  

The spacecraft is being produced in Lockheed’s Denver facility. The company has integrated technologies like augmented reality and digital twins to speed up production of the 12 GPS IIIF satellites it is under contract to build.

GPS IIIF will feature Regional Military Protection as one of its upgrades, delivering more than a 60‑fold boost in anti‑jamming performance for warfighters, an increase in resistance to hostile interference that will help U.S. forces stay ahead of EW threats.

Tuesday’s launch gets us one step closer to that. 

“The final GPS III deployment is an important milestone as we continue strengthening the GPS constellation,” said Fang Qian, vice president of GPS at Lockheed Martin. “By launching SV10 into orbit, we’re not only adding to the resiliency of today’s GPS capabilities—we’re opening the door to the next generation of GPS IIIF satellites that will provide greater resiliency and serve as the backbone of the GPS constellation for years to come.”

The four-year contract, which began March 31, 2026, will advance GNSS radio occultation (GNSS-RO), polarimetric radio occultation (GNSS-PRO), and reflectometry (GNSS-R) capabilities. 

As the largest commercial provider of GNSS-RO data, PlanetiQ currently operates a global constellation of satellites equipped with advanced receivers capable of capturing high signal-to-noise-ratio GNSS-RO and GNSS-PRO measurements. GNSS-PRO has demonstrated strong efficacy for measuring precipitation, a key capability for improving severe weather forecasting. 

The STRATFI award extends that foundation in two directions. PlanetiQ will refine data-assimilation techniques to integrate GNSS polarimetric radio occultation data into numerical weather models, which improves the characterization of precipitation. The next-generation receiver will also add GNSS-R capabilities, supporting new applications such as ocean surface wind measurement, sea state characterization, and soil moisture monitoring over land. Data delivered will support Air Force applications including AI model training, data assimilation, and performance evaluation.

“This award is a big indication from the U.S. government that our technology matters and they are willing to put $15 million toward it,” said Chris McCormick, PlanetiQ chairman and founder. CEO Ira Scharf added that combining the three measurement types in a single platform would unlock “a more complete picture of the atmosphere and Earth’s surface.”

The Air Force contract builds on a string of government data agreements. In September 2025, NOAA awarded PlanetiQ a $24.3 million contract under the Commercial Data Program’s Radio Occultation Data Buy 2 — the agency’s single largest commercial satellite weather data purchase. Under that agreement, PlanetiQ delivers 7,000 GNSS-RO profiles per day, including 500 enhanced high-SNR profiles described as more than seven times higher in quality than profiles from other commercial providers, along with 2,500 low-latency Total Electron Content tracks daily. While NOAA is the procuring agency, the data is also used by NASA, the U.S. Air Force, the U.S. Navy, and international government weather agencies. 

The STRATFI program is administered through AFWERX, the innovation arm of the Department of the Air Force and a directorate within the Air Force Research Laboratory, which has awarded more than $7.24 billion in contracts since 2019 to accelerate technology transition to operational capability. 

PlanetiQ was founded in 2015 by McCormick, who previously led Broad Reach Engineering, a pioneer in GPS radio occultation sensors for missions including COSMIC, before its acquisition by Moog in 2012.

Formally designated the LN-351, the system incorporates fiber-optic inertial navigation paired with Military-code (M-code) GPS — an encrypted, military-specific signal providing enhanced resistance to jamming and spoofing. A capability called Blended Navigation Assurance validates GPS data integrity even when signals are under threat.

The software architecture allows operators to host third-party PNT applications without manufacturer involvement, enabling integration of complementary sensors and tracking of non-GPS satellite constellations. The design completed rigorous hardware and software testing to military specifications ahead of full-scale production.

“EGI-M enhances operational effectiveness and is built with the flexibility to defeat today’s threats and adapt to future mission demands,” said Ryan Arrington, vice president of navigation and cockpit systems at Northrop Grumman. Lt. Col. Chris Grover of the U.S. Air Force described the system as enabling mission execution “where we want to, with the capability we need, at the time of our choosing.”

Upon full production, military customers will receive a unified hardware and software navigation solution designed for seamless integration across platforms.

The delivery comes as GPS jamming and spoofing have emerged as routine features of modern conflict. Across Ukraine, the Middle East, and the Baltic region, documented interference has degraded navigation for both military and civilian operators, accelerating demand for M-code-capable and multi-constellation PNT solutions across allied air forces.

The functionality will be available as a software option for the R&S SMBV100B and R&S SMW200A vector signal generators, giving device manufacturers a production-ready pathway to test and validate receiver compatibility with Pulsar signals ahead of the constellation’s commercial deployment.

Pulsar is designed to complement existing GNSS infrastructure — including GPS — by leveraging LEO orbital geometry to deliver stronger signals, improved accuracy, and enhanced resilience against jamming and spoofing. Where legacy GNSS constellations operate in medium Earth orbit at altitudes above 20,000 kilometers, LEO satellites orbit at roughly 500 to 2,000 kilometers, resulting in significantly stronger received signal power and reduced signal travel time. The tradeoff is that individual satellites pass overhead quickly, requiring a larger constellation to maintain continuous coverage — which Xona is building toward commercial scale.

The practical challenge Rohde & Schwarz is addressing is the test gap that precedes a new signal type’s deployment. Before device manufacturers can build and certify receivers that support Pulsar, they need the ability to simulate Pulsar signals in a lab environment — verifying receiver performance against known signal parameters without requiring an operational constellation overhead. Adding that simulation capability to established signal generator hardware provides an accessible, production-scalable route for validation.

“Navigation technology is entering a period of rapid evolution,” said Matt Hammond, North America Satellite Technology Manager at Rohde & Schwarz. “By adding Pulsar signal simulation to our signal generator portfolio, Rohde & Schwarz is preparing our customers for the next evolution of satellite navigation.”

“Test and measurement solutions play an important role in enabling device manufacturers to evaluate compatibility as new signals become available,” said Bryan Chan, co-founder and VP of Strategy at Xona Space Systems. “Rohde & Schwarz brings deep expertise in precision signal generation that helps make this possible.”

The R&S SMBV100B and R&S SMW200A will join Pulsar’s verified ecosystem program, which recognizes devices and test solutions validated for compatibility with Pulsar signals. Rohde & Schwarz showcased its navigation test solutions at Space Symposium 2026 in Colorado Springs this week.
