In order to preserve operational capability in GPS/GNSS-denied, degraded, or disrupted space operating environments (D3SOE), VIAVI Solutions introduces its second-generation RSR Transcoder.
As GPS and GNSS jamming and spoofing techniques become more commonplace in electronic warfare, their occurrences have increased globally.
These hostile signal manipulations are intended to interfere with military activities, but they also represent an increasing risk to industries like emergency services, communications, and aviation that depend on exact timing and localization.
To upgrade legacy systems, the second generation RSR Transcoder provides guaranteed Position, Navigation, and Timing (PNT) in a variety of outputs. It has a GPS full constellation simulator and converts guaranteed inputs like M-code, SAASM, IMU/INS, and other signals of opportunity almost instantly using a unique technique.
To make it simple to upgrade any legacy GPS with guaranteed PNT capabilities, these are transformed to Universal GPS L1 and L2 signals with C/A-code and P-code output.
Mountable on land, sea, and air platforms, the ruggedized IP68 enclosures are designed to operate in a secret lights-out mode. The transcoder features an ICD-GPS-153 interface, outputs at 100 Hz, and comes with carryover oscillator options of 4, 8, and 24 hours.
The Departments of Defense and Homeland Security are co-hosting the 2025 Joint Navigation Conference, which will take place in the Greater Cincinnati Area from June 2–5 and feature a demonstration of the RSR Transcoder. It will be on display at booth #406 of VIAVI. At booth #430, VIAVI’s Inertial Labs branch will also showcase the latest advancements in D3SOE navigation.
VIAVI and its Inertial Labs division will also give three presentations:
- “3D Vision-Based Positioning for Autonomous Aerial Platform Navigation and Human-in-the-Loop Reconnaissance Mission”: Monday, June 2 at 1:50 PM ET
- “Anti-Jam/Spoof Phased Array Antenna”: Wednesday, June 4 at 10:50 AM ET
- “Retrofitting At-Risk GPS Defense Equipment with a Multi-Orbit LEO and GEO Clock System for Resilient PNT Services”: Wednesday, June 4 at 11:30 AM ET
Leadership Comments
“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,” said Doug Rusell, Senior Vice President, Aerospace & Defense, VIAVI. “The RSR Transcoder enables cost-effective upgrades to legacy systems with state-of-the-art resilience against such attacks.”
