Inertial Systems

GPS-Aided Inertial Navigation Systems (GPS-Aided INS) that combine the strengths of MEMS or FOG Inertial Measurement Units (IMU) with multi-constellation (L1, L2, L5, L6) and multi-band (GPS, GLO, GAL, BDS, QZSS, NAVIC) Global Navigation Satellite System (GNSS) receivers. Our INS utilize IMUs containing MEMS accelerometers and MEMS or FOG gyroscopes to track position and attitude, tightly coupled with GNSS data to correct for inherent drift and errors. This combination provides highly accurate and reliable navigation solutions, particularly in GNSS-jammed, spoofed, or denied environments. Our INS support multiple aiding data sources including Doppler shift, camera visual navigation, radar and DVL, external magnetic compass, air data computer, external heading and position updates, LEO receivers, and M-Code/SAASM receivers. All systems are ITAR-free, affordable, and available with very short lead times, with special firmware supporting tight integration with commercial autopilots like Pixhawk and Ardupilot.

We also provide Attitude and Heading Reference Systems (AHRS) that are a fusion of Inertial Measurement Unit (IMU) with miniature Fluxgate Magnetometer, providing information about an object’s orientation (attitude) and heading in three-dimensional space. AHRS systems function like advanced electronic gyroscopes, offering more accurate and reliable data than traditional mechanical gyroscopic instruments for applications in aviation, robotics, and autonomous vehicles. Additionally, we offer Optically-Enhanced Attitude and Heading Reference Systems for applications like 81 mm and 120 mm mortars Fire Control Systems (MFCS) to measure Azimuth / Deflection with 3 MIL accuracy and Pitch / Elevation with 1 MIL accuracy under mortars operational environmental conditions.
