DRU-H-R Dynamic Reference Unit-Hybrid Replacement
The DRU-H-R (Dynamic Reference Unit-Hybrid Replacement) delivers high-precision mission-critical position and attitude data for vehicle navigation and platform pointing and positioning. Ideal for unmanned vehicles and naval environments, the combat-proven system has been utilized in U.S. Army artillery systems and counter-artillery radars.
The DRU-H-R can be optionally enhanced with an embedded Selective Availability Anti-Spoofing Module (SAASM) GPS with M-code capability.
