Single and dual antenna GPS-aided Inertial Navigation System – INS

Bestech Australia has released a new generation of fully-integrated INS, combined L1 & L2 GPS, GLONASS, GALILEO and BEIDOU navigation and high- performance strapdown system. The system can determine position, velocity, heave and absolute orientation (heading, pitch and roll) for any equipment on which it is mounted. Horizontal and vertical position, velocity, heave and orientation are determined with high accuracy for both motionless and dynamic applications.

The Inertial Labs INS (inertial navigation system) utilises advanced single and dual antenna GNSS receiver, barometer, three axes each of calibrated in full operational temperature range precision fluxgate magnetometers, accelerometers and gyroscopes to provide accurate position, velocity, heading, pitch and roll of the device under measure. INS contains Inertial Labs’ new on- board sensors fusion filter, state of the art navigation and guidance algorithms and calibration software.
