Design and Implementation of Wireless Data Link Calibration Equipment of UAV

UAV system with a wireless data link for the calibration and test objects, designed and implemented a wireless data link system calibration equipment, medium-range UAV system to solve the simple means of technical support, equipment calibration testing process takes a long time, personnel, results poor reliability and accuracy problems. Test and results showed that the use of force: a reasonable system design, calibration, testing methods of science, advanced technology, stable performance, with medium-range UAV wireless data link for the key performance indicators calibration and testing functions. Keywords-unmanned aerial vehicles, wireless data link, transmit power, receiver sensitivity, bit error rate I. INTRODUCTION UAV system, wireless data link system performance impact of its operational use is always a key factor in grassroots units not equipped with the appropriate testing equipment, only use low-power near-field signal for qualitative features observed; separated by aircraft and ground stations 5 km away from the high power signal pull test, the wireless data link to a rough assessment of the technical state of the system. Sometimes the signal is unstable and smooth and can not clear why. Through to the transmit power, receive sensitivity, bit error rate measurement parameters, comprehensive and accurate assessment of the UAV data link system wireless technology performance, provide the basis for the UAV operational commanders. Medium-range UAV system to the existing test methods based qualitative test, test indicator species, a small number of test results unreliable, difficult to accurately assess medium-range UAV system-wide performance. In the medium-range UAV wireless data link control loop calibration test in the test methods introduced in order to send remote commands and receive telemetry data, through two lines to send and receive, in the process of calibration and testing form a closed signal detection loop, build a dynamic online test environment, the state controlled UAV system calibration and testing of integrated performance. Detection method to solve a single system, low accuracy, quantitative analysis of the problem can not be.
