Design and Implementation of Angular Sensor in Radio Positioning System
According to the Index Requirements of Radiolocation in a small aircraft, a Digital high-precision angular sensor is designed. Based on the design idea of multi-stage rotary transformer as angular displacement of the collector, introduced the principle of angle sensor, give the detailed design of hardware, described data collection, data processing and coding methods. Through laboratory static testing and dynamic testing, the test results with the static and dynamic shows GPS azimuth fit data well. Error analysis shows that: In this paper, the angular sensor designed, precision target to meet the system requirements may be applied to other areas of the angular displacement measurement system.
