BD2 Attitude and Direction-Finding System
Product profile and purpose
It consists of front antenna, rear antenna, connecting cable and host, and its purpose is to substitute the original gyroscope north finder, so as to reduce the cost and increase GPS characteristic parameters, as well as increase the use reliability and improve the north-finding accuracy. It is compatible with the original installation dimension, and can reliably output and display the north-finding angle and other data.
