(VIAVI: Chandler, AZ) – VIAVI Solutions has launched its second-generation RSR transcoder, created to maintain operational capability in GPS/GNSS-denied, degraded, or disrupted space operational environments (D3SOE).

Globally, incidents of GPS and GNSS jamming and spoofing have surged as these tactics become a standard aspect of electronic warfare. While aimed at disrupting military operations, these hostile signal manipulations also pose a growing threat to sectors reliant on precise timing and geolocation, including aviation, communications, and emergency services.

The second-generation RSR transcoder delivers ensured position, navigation, and timing (PNT) in a wide range of outputs to upgrade legacy systems. It includes a GPS full constellation simulator and uses a patented algorithm to provide nearly instant conversion of ensured inputs such as M-code, SAASM, IMU/INS, and other signals of opportunity. These are converted to universal GPS L1 and L2 signals with C/A-code and P-code output to enable the easy upgrading of any legacy GPS with ensured PNT capability.

The rugged IP68 enclosures can be mounted on land, sea, and air platforms, and have been developed to run in a covert lights-out operation mode. The transcoder outputs at 100 Hz, has an ICD-GPS-153 interface, and is available with 4-, 8- and 24-hour holdover oscillator options.

“Modern military systems are heavily reliant on PNT technologies, but advances are enabling adversaries to jam and spoof GNSS, forcing those fighting, as well as equipment such as drones, to operate in D3SOE,” says Doug Russell, senior vice president, Aerospace & Defense at VIAVI. “The RSR transcoder enables cost-effective upgrades to legacy systems with state-of-the-art resilience against such attacks.”
