High-precision Inertial Navigation Module

Date2017-01


Product introduction:

 The Trimble Aardvark DR+GPS module combined with dead reckoning (DR) and GPS signal, even in the most difficult conditions, but also can produce timely and accurate positioning results. On the basis of the previous effective position, the module is used to estimate the position according to the following course and moving distance. Speed, time course and input information more accurately, the dead reckoning (DR) higher accuracy. GPS is also here to play a role. GPS produces the best results by continuously correcting the gyro and the speed sensor. In the case of GPS signal is extremely poor, the sophisticated DR+GPS algorithm to automatically calibrate the sensor and integrated sensor and GPS signal input to generate accurate position and speed output.

Module advantage:

All in one, DR+GPS+ gyroscope
■No GPS signal can provide accurate, stable and reliable inertial navigation
■Self calibration (self-calibration) sensor mounting angle
■Three axis accelerometer with support plate (on-board) or plug in
■Support HIPPO and NMEA protocol
■Aiming at the seamless positioning
■The application of simple, only need to provide the speed pulse line and reverse signal line can be
■I - C interface to access additional.
