Design and Implementation of Test System for Magnetic Compass based on Labview

The magnetic compass is often as the key components for heading angle measurement on the unmanned aerial vehicle （UAV）. In order to test its performance, an intelligence measurement system for magnetic compass based on PXI bus computer and other hardware parts and Labview software is designed， which has realized various performance tests. At the same time, the system has a friendly interface and is able to save the test data. The practical application shows that the system is stable, easy operation, and can detect the magnetic compass fault before the installation of UAV parts for the flight, which improves the UAV flight safety.
