Inertial Systems
Reliable navigation requires continuous and accurate position, velocity and orientation data—even when satellite signals are unavailable, degraded, jammed or spoofed. General Guidance provides advanced inertial navigation systems from Inertial Labs and JAVAD GNSS, developed for reliable operation in GNSS-enabled, GNSS-challenged and GPS-denied environments.
Our portfolio includes Attitude and Heading Reference Systems (AHRS), single- and dual-antenna GNSS-aided Inertial Navigation Systems (INS), compact OEM modules, rugged tactical navigation systems, Fiber Optic Gyroscope-based solutions and advanced vision- and LEO-aided navigation technologies. By combining calibrated gyroscopes and accelerometers with GNSS, magnetometers, optical sensors and other available aiding sources, these systems provide accurate heading, pitch, roll, position and velocity across a wide range of operating conditions.
Selected solutions also provide enhanced navigation continuity and protection against GNSS interference, including jamming and spoofing detection, mitigation and alternative positioning technologies. This enables dependable performance in a GPS-denied environment where conventional satellite navigation alone cannot provide the required accuracy or availability.
Designed for UAVs, UGVs, autonomous vehicles, aircraft, maritime platforms, surveying and mapping systems, antenna-pointing applications and defense operations, these inertial systems support both embedded integration and complete platform-level deployment. Whether the requirement is a lightweight OEM INS for an unmanned vehicle or a rugged high-performance navigation system for mission-critical applications, General Guidance can help identify the appropriate technology and configuration.
