The SDN500 is a premier GPS/INS Tactical Grade System, engineered for high-quality performance in demanding military applications. This compact system integrates state-of-the-art quartz gyros, quartz accelerometers, high-speed signal processing, and a 48-channel Coarse/Acquisition (C/A) Code GPS receiver. For enhanced security, it offers the option of a Selective Availability Anti-Spoofing Module (SAASM) GPS receiver.

Key Features:

  • Precision and Accuracy: Achieves a reliable 3.9 meter Spherical Error Probable (SEP) with GPS-aided accuracy.
  • Robust Performance: Proprietary Quartz MEMS Inertial Sensors ensure continued position and attitude accuracy even if GPS tracking is lost.
  • Compact and Lightweight: Modular design with a compact 25 in³ size, weighing less than 1.6 lbs, ideal for integration in space-constrained environments.
  • Enhanced GPS Tracking: 48-channel GPS tracking for superior coverage and less than 35-second time-to-first-fix (TTFF) from cold start.
  • High-Speed Data Processing: Provides enhanced 100Hz position data with customer-programmable output data rates.


The SDN500 is designed for integrator and OEM use in a variety of critical military applications, including:

  • Defense UAVs, Helicopters, and Fixed-Wing Aircraft: Ensures precise navigation and control for aerial operations in diverse environments and combat conditions.
  • Missile & Precision Guided Munitions Systems: Integral for missile targeting, guidance, and control, ensuring precise delivery and effectiveness. Delivers accuracy for munitions requiring precise targeting and impact.
  • Platform Stabilization: Provides stable and reliable platform positioning for various defense systems.
