GPS-Aided Vertical Gyro


The LandMark™ 20 VG/GPS is a low noise GPS-aided vertical gyro. The unit features very low noise gyros and accelerometers with exceptional bias in-run and bias over temperature performance with integrated GPS-Aiding in a small, light weight and low power ruggedized package.


The inertial suite provides internally temperature compensated RS485 output of delta velocity, delta theta, heading, pitch and roll angles and altitude information in a ruggedized package.


All units are integrated with a 72 channel C/A code GPS receiver with up to 18Hz GPS position update rate. GPS aiding is included in all units for turning error correction as well as for continued output during short-term GPS dropouts.





6 Degrees of Freedom MEMS VG/GPS


The LandMark™ VG/GPS provides delta velocity and delta theta information and also provides GPS heading as well as roll and pitch (degrees) and GPS altitude (meters) outputs enabling position determination from a known starting point.


The GPS receiver is a 72 channel C/A code GPS receiver and offers up to 18Hz GPS position update rate. The low power receiver supports GPS, GLONASS, BeiDou, GALILEO and SBAS (WAAS, EGNOS, MSAS).
