MEMS GPS/INS




        SDN500 GPS/INS Tactical Grade Navigation System
        Our most advanced MEMS GPS/INS tactical grade system, the compact SDN500 combines latest
        generation quartz gyros, quartz accelerometers, high-speed signal processing, and a 48-chan-
        nel Coarse/Acquisition (C/A) code GPS receiver into a powerful, tightly coupled guidance and   QUARTZ MEMS
                                                                                                QUARTZ MEMS
        navigation system. There is also an option to utilize a Selective Availability Anti-Spoofing Module
        (SAASM) GPS receiver. Our proprietary quartz MEMS inertial sensors maintain position and
        attitude accuracy in the event of loss of GPS tracking. The low-power SDN500 is designed for
        integrator and OEM use in the latest demanding, smaller, and more scalable system applications.
