Description

XW ADU**1 Directional Attitude Measurement System combines the most advanced GPS and Inertial Navigation Technology, Carrier Phase Measurement and Embedded DSP Design Technology, to overcome the shortcomings of single instrumentation and strengthen the suitability of the product. This system delivers better accuracy, dynamic performance and higher reliability. XW ADU**1 consists of one GPS receiver and the IMU, delivering high accuracy, fast startup, best dynamic performance and strong interference resistance. According to the requirement, it could be also enhanced with electronic compass to assist direction seeking and it could output the data of direction, position, velocity, time and attitude etc. The product is ideally suitable for high dynamic carriers. XW ADU***-A is the MEMS Inertial package while XW ADU***-B is the Fiber Optic Inertial package.
