M-Code compatible navigation which provides higher levels of protection against GPS jamming and spoofing is now available in Europe with Collins Aerospace unveiling its NavHub™-200M vehicular navigation solution on the first day of the Eurosatory land and air defence show in Paris.

The NavHub™-200M is the first non-ITAR vehicular navigation system for the international market compatible with the Military Code (M-Code) receiver technology. M-Code features improved resistance to anti-jamming and secure access of military GPS signals.

The solution provides assured positioning, navigation and timing (APNT) and resistance to threats such as Global Positioning Systems (GPS) jamming and spoofing. In Ukraine, for example, Russian jammers are targeting GPS satellite signals, which prevents Ukrainian forces from receiving any usable signal. 

Collins Aerospace says the solution will ensure faster and more accurate performance for ground vehicles on the connected battlespace.

With GPS-based Selective Availability Anti-Spoofing Module (SAASM) receivers set to become obsolete, Ryan Bunge, vice president and general manager, Communication, Navigation and Guidance Solutions for Collins Aerospace says it is critical that M-Code receiver technology is made available to ground forces around the world as quickly as possible so they can trust that the signals they receive in a fast-moving, hostile environment are accurate and actionable. “Our NavHub-200M provides an improved resistance to jamming and interference, as well as advanced security features to prevent unauthorised access or exploitation.”

NavHub-200M also includes the open interface standards and sensor fusion capabilities required for a Global Navigation Satellite System (GNSS) upgrade path, such as for Europe’s Galileo constellation. It can also interface with key vehicle sensors such as the inertial measurement unit (IMU) and odometer, among others.
