POLA V16B MEMS Inertial/Satellite Integrated Navigation System
POLA V16B is a high-performance and cost-effective MEMS inertial/satellite integrated navigation system. Built in three-axis gyroscope, three-axis accelerometer, high-precision barometer, and a BD/GPS/GLONASS/ALILEO quad mode receiver. It can measure the speed, position, and attitude of the carrier, as well as output compensated angular velocity, acceleration, air pressure, temperature, and other information. Optimization algorithm for tree occlusion environment in urban buildings to achieve high-precision navigation and positioning.
