Inside GNSS

Xona Space Systems has introduced Pulsar Verified, a partnership program that certifies receivers, chipsets, and test equipment for interoperability with the company’s Pulsar low Earth orbit positioning, navigation, and timing signal, said Tyler Reid, co-founder and CTO at Xona.

Jericho Receivers, a subsidiary of All 6G, has announced commercial availability of its Software-Defined Atomic Clock (SDAC), a timing device designed to maintain atomic-clock-grade accuracy by fusing multiple independent references rather than relying on a single source.

Readers will not be surprised to learn resilience was a major focus at Eurosatory 2026. Across giant exhibit halls packed with the latest military gear, companies and customers were discussing how autonomous systems, sensors and communications networks can continue operating in increasingly contested environments. For Canada’s Calian, the answer begins with the best possible GNSS reception.

Iridium Communications Inc. (Nasdaq: IRDM) announced July 6 that it has completed its acquisition of Aireon LLC, operator of the space-based Automatic Dependent Surveillance-Broadcast (ADS-B) air traffic surveillance system.

Tersus GNSS has launched the AG993, a modular autosteer retrofit kit for agricultural vehicles that pairs high-precision GNSS positioning with the company’s proprietary TAP (Tersus Advanced Positioning) satellite correction service alongside conventional RTK support. The system targets better-than-2.5 cm accuracy across a 0.2–30 km/h working speed range, with support down to 0.1 km/h and standard automatic headland U-turns.

Jamming and spoofing of GNSS signals to prevent use of GNSS or to alter user position solutions has become a significant concern over the last decade, as discussed in many recent papers and articles. These events can now be visualized within a day or two of occurrence at websites that use ADS-B transmissions to infer the locations and types of jamming and spoofing, such as [2]. Real-time detection, mitigation and avoidance of these events is now one of the most active areas of GNSS research.

Pacific Defense has received a contract from the U.S. Army Program Manager Positioning, Navigation and Timing (PM PNT) to develop a Block 2 Assured Position, Navigation and Timing (APNT) plug-in card under the CMOSS Mounted Form Factor (CMFF) program. The Block 2 APNT PIC is a rugged 3U VPX card aligned to The Open Group Sensor Open Systems Architecture (SOSA) and C5ISR Modular Open Suite of Standards (CMOSS).

Rocket Lab Corporation and Iridium Communications Inc. announced today a definitive agreement under which Rocket Lab will acquire all outstanding shares of Iridium common stock for $54 per share in a cash and stock transaction, implying an enterprise value for Iridium of approximately $8.0 billion. The deal carries significant implications for the alternative PNT sector.

Taoglas has introduced the GVLB208 series, a dual-band L1/L5 GNSS stacked patch antenna family in a 20 mm x 20 mm x 8 mm footprint. The series is available in passive (GVLB208.A) and active (AGVLB208.A) configurations, both using a single-feed architecture that supports concurrent L1 and L5 reception without the complexity of multi-feed designs.

NASA has awarded PlanetiQ an expanded contract through its Commercial Smallsat Data Acquisition (CSDA) program, adding high signal-to-noise ratio (SNR) GNSS polarimetric radio occultation (PRO) data to the company’s existing CSDA portfolio. PlanetiQ already provides NASA with ionospheric scintillation data, ionospheric total electron content measurements, and high-SNR GNSS radio occultation data under the program.
