Rocket launching is a high speed state of complex system. The rocket telemetry data shows values of working parameters and environmental parameters toward each system in the flight course. Rocket telemetry data with great variety and large quantity, can be compressed to improve communication efficiency and lower storage space requirement. By analyzing the frame format, correlation and statistical characteristics of rocket telemetry data, Lossless rocket telemetry data compression method is given based on undistorted information reorganization, in order to improve compression ratio. Experiments showed the feasibility of that method. Compare to general compression algorithms, the compression rate can be increased by 10-15%.
