VIAVI Solutions, has introduced its second-generation RSR Transcoder, designed to ensure operational capability in GPS/GNSS-denied, degraded, or disrupted space operational environments (D3SOE). This advanced solution addresses the escalating threats of GPS and GNSS jamming and spoofing, which pose significant risks to military operations and sectors reliant on precise timing and geolocation, such as aviation, communications, and emergency services. The RSR Transcoder delivers assured Position, Navigation, and Timing (PNT) by converting various assured inputs-including M-code, SAASM, IMU/INS, and other signals-into universal GPS L1 and L2 signals with C/A-code and P-code outputs, facilitating the upgrade of legacy systems.

Encased in ruggedized IP68 enclosures suitable for land, sea, and air platforms, the device operates in covert lights-out mode, outputs at 100 Hz, and offers 4-, 8-, and 24-hour holdover oscillator options. Doug Rusell, Senior Vice President, Aerospace & Defense at VIAVI, stated, “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. The RSR Transcoder enables cost-effective upgrades to legacy systems with state-of-the-art resilience against such attacks.” The RSR Transcoder will be showcased at the 2025 Joint Navigation Conference, held June 2-5 in the Greater Cincinnati Area, at VIAVI’s booth #406.
