 5 October 2005 -- Inertial Aerosystems announces the availability of a new, cost effective, precise position and attitude system that it says provides higher performance than either a GPS or inertial system can provide independently. The system comprises a compact ring laser gyro inertial measurement unit (IMU) disciplined by a GPS receiver fitted with exclusive firmware which includes multiple Kalman filters. This innovative system gives uninterrupted position and heading despite the loss or intermittent failure of satellite signals and has fast recovery on re-capture of signals.

Simultaneously, outputs of velocity, acceleration, pitch, and roll are continuously computed with ultimate performance when GPS is available.

This versatile system is said to be ideal for system integrators, test house and Research Laboratories where precise measurements are required.

Other applications include manned and unmanned vehicles, marine surveying and fishing, seismic exploration, oil drilling, radar antenna stabilisation, structural and geotechnical monitoring.
