TopStar M is a range of GNSS receivers with high-performance accuracy, integrity, anti-jamming, anti-spoofing and SAASM functionalities, for demanding platforms such as helicopters, UAVs, radar, missiles, fighters and surface ships.

GNSS receivers for military GPS/GALILEO

A wide range of battlefield-proven applications

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.
Thales offers three different receivers: the GNSS 1000-S, a single boardimplementing 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.

GNSS 1000-S: The European SAASM solution

GNSS 100-2 & 100-3: standalone solution

  • Standalone GPS receiver with 24-channel all in view concept
  • Three versions:
    - Legacy P(Y) code with PPSSM & AOC
    - C/A and GLONASS: for export programs
    - P(Y) code with SAASM: for authorised countries
  •  High levels of performance required for fighters and standoff missiles and helicopters 
  • Interfaces: Several I/O versions available:
    - ARINC 429 or MILSTD1553B or DIGIBUS
    - RS 422
    - NMEA

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.
