Abstract:

In order to meet the requirements of high-density space launch missions, an analysis was conducted on the decoding and display process of telemetry images, the processing mechanism ,errors, and their effects on the real-time telemetry image display of a certain model of telemetry decoding system, which is inconsistent with the flight time calculated by the data center. The alignment and calibration methods of takeoff and calibration methods of takeoff and flight were also discussed. An innovative strategy was proposed to receive the takeoff and flight time of the data center according to priority, and the optimized flight time was superimposed on the real-time telemetry image. Through experimental verification, this method can reliably and stably superimpose real-time flight time onto telemetry images, ensuring accurate synchronization between the real-time telemetry image and the flight time calculated by the data center.
