Kearfott’s INS/GPS provides high performance in a small, lightweight envelope for a wide variety of applications spanning from rotary to fixed-wing platforms, manned or unmanned. Utilizing Kearfott’s Monolithic Ring Laser Gyro (MRLG) and MOD VIIA pendulous accelerometers, the INS/GPS provides heading, attitude, velocity, and position information necessary for navigation. The INS/GPS system tightly couples the inertial sensors with an Embedded GPS Receiver (EGR) capable of providing the performance needed while operating through adverse environments. For configurations requiring PPS capability, the EGR utilizes a proven 24-channel GPS SAASM engine able to provide high accuracy measurements under extreme conditions, and provides real-time Receiver Autonomous Integrity Monitoring (RAIM) and Fault Detection and Exclusion (FDE) per RTCA/DO-229. An SPS configuration is available for applications not requiring PPS capabilities. Primary communication consists of MIL-STD-1553B, RS-422, and/or RS-232, depending on application needs.
