Test Of Key Indicators For UAV Remote Telemetry System

Before the UAV remote telemetry system being loaded onto the aircraft, indicators of the system should be tested. Only parameters of the system in line with the targets, can it be accepted. As UAV manufacturing units, researching the methods of indicator assessment and identifying a set of accurate, simple and economical methods is needed.This paper studies the test methods of key indicators of the UAV remote telemetry system. This article first discusses the subject of research background, research purposes, and research content. And then discusses the test methods of working distance and the location of the attenuator in the experiment. We also do theoretical analysis on the impact of the attenuator when connected to the receiving end. And the experimental results are given. And then discusses the accuracy of the positioning test. The principles of GPS positioning and differential GPS test methods are described. The results of differential GPS base station measurement experimental are given. And then we discuss how to test the bit error rate, code rate and antenna maximum tracking speed. The bit error rate statistical software and the code rate test software have been achieved. At last, we do a summary and pointed out the inadequacy of some methods.This topic studies UAV remote telemetry system to each of these key indicators of testing methods. And in accordance with theory and experiment we summarized a set of accurate, simple and easy methods. It has practical value.
