GI-V5B is a cost-effective MEMS inertial/satellite integrated
navigation system. It has a built-in triaxial gyro, triaxial
accelerometer, triaxial magnetic sensor, a pneumatic sensor, and a
BD/GPS/GLONASS/GALILEO four-mode receiver. The velocity, position
and attitude of the carrier can be measured, as well as the output
compensated angular velocity, acceleration, magnetic course, air
pressure, temperature and other information.
Feature
