TopStar M, military GPS/GNSS receivers for mission success
The worldwide premiere generation of military receivers GPS & Galileo for critical operations
TopStar M is a cutting-edge range of military GNSS receivers designed for mission-critical platforms. Equipped with advanced capabilities such as anti-jamming and anti-spoofing, TopStar M delivers exceptional performance for demanding military applications, including helicopters, UAVs, missiles, fighters, radar systems, and surface ships.
Proven reliability in battlefield conditions
For more than 30 years, Thales military receivers have been onboard numerous platforms, with thousands of units delivered worldwide. These reliable receivers have been integrated into systems such as missiles, fighters, air transport, helicopters, patrol aircraft, surface ships, UAVs, radar, and fire control systems. All TopStar M receivers are suitable for both linefit and retrofit programs.
What is an anti-jamming solution?
An anti-jamming solution refers to a set of technologies and techniques designed to protect signals—especially those from Global Navigation Satellite Systems (GNSS)—from intentional interference or jamming. These solutions are crucial for ensuring the reliability and continuity of critical systems, such as navigation, communication, and defense applications, even in hostile environments. By minimizing the impact of jamming attempts, anti-jamming technologies help maintain the accuracy and integrity of satellite-based systems, which are essential for both civilian and military operations.
Best anti-jamming performance levels
The TopStar M GNSS receiver delivers exceptional anti-jamming and anti-spoofing capabilities, setting new standards in signal protection and reliability. By leveraging two independent encrypted signals, it offers robust resistance against intentional interference and unauthorized spoofing attempts.
Key features include:
- Selectable solutions: GPS/Galileo merged solution, GPS-only, or Galileo-only options.
- Dual-Signal encryption: Superior protection using two distinct, independently encrypted signals.
- Modular architecture: Fully adaptable design supporting Galileo PRS and Galileo Open Service.
- Superior anti-jamming performance: Our patented algorithms exceed GRAM performance standards, providing ultra-fast Direct-PRS and Direct-M code acquisition on all L1/L2 and E6 frequencies.
- Integrated NAVWAR Functions: Built-in capabilities for enhanced anti-jamming and reliable spoofing detection.
Full in-house design
- The highly efficient multi-correlation and hybridization algorithms provide high performance acquisition time and dynamics.
- The GPS M-Code technology is compliant with CI-MGUE 861 GRAM-SM specifications.
Advanced GNSS technology for secure and reliable navigation
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 two different receivers:
- the TopStar M receiver module, a single board implementing all military functions,
- and the TopStar M receiver, a packaged version of the TopStar M receiver module with ARINC, 1553 or NMEA and time server interfaces.
