Introducing the DRU-H-R: Advanced Positioning Technology
The Dynamic Reference Unit-Hybrid Replacement (DRU-H-R) is engineered to provide precise and reliable position and attitude data, essential for navigation and platform orientation in various applications. This system is particularly suited for unmanned vehicles and maritime operations,having demonstrated its effectiveness in U.S. Army artillery and counter-artillery radar systems.
Enhanced Capabilities
For added functionality, the DRU-H-R can be equipped with an optional Selective Availability Anti-spoofing Module (SAASM) GPS, featuring M-code capabilities to enhance security and accuracy.
