TopStar M military GPS/GNSS receivers

Battlefield-proven GNSS receivers for military GPS/GALILEO

Air defence
Drone warfare
Fighter

For more than 30 years, Thales military receivers have been on board numerous military platforms with thousands of units delivered: missiles, fighters, air transport, helicopters, patrol aircraft, surface ships, UAVs, radar, fire control systems, etc. They are all suitable for both linefit and retrofit programs.

FORCES

Battle-Tested Precision

With 30+ years of operational deployment across fighters, UAVs, ships, and missiles, TopStar M GNSS ensures battlefield-proven navigation performance. Thousands of units delivered underline its unmatched reliability and robustness in mission-critical conditions.
SAASM & Anti-Jamming Power

TopStar M receivers deliver military-grade capabilities, including SAASM support, direct Y-code acquisition, and high anti-jamming resilience. Compatible with TopShield and TopAxyz, they ensure optimal accuracy and signal protection in hostile environments.
Flexible, Export-Ready Design

Available in multiple configurations (GNSS 1000-S, 100-2, 100-3), TopStar M supports a range of interfaces (ARINC, MIL-STD-1553, RS 422) and modes (P(Y), C/A, GLONASS). It suits both authorized and export programs with scalable performance and easy integration.

Achieving higher performance with Thales solutions

Coupled with the Thales anti-jamming solution TopShield, and the inertial solution TopAxyz, or with any other inertial or CRPA anti-jamming system, Thales GNSS receivers provide smart and efficient solutions for the most demanding applications.

Thales offers three different receivers: the GNSS 1000-S, a single board implementing all military functions, the GNSS 100-2, a packaged version of the GNSS 1000-S with ARINC, 1553 or NMEA interfaces, and the GNSS 100-3, a packaged version of the GNSS 1000-S with RS 422 interface.
