The Telemetry and Ranging Using the GMSK Modulation

A modulation technology known as GMSK which transmitting the Ranging and Telemetry simultaneously has been analyzed and simulated. It can improve the efficiency of frequency spectrum using the GMSK modulation to transmit the Telemetry and Ranging simultaneously. It analyses the different algorithms of modulation and demodulation in the project, and illuminates the realization of them. The performances of Ranging and Telemetry and the precision of Ranging for different algorithms have been acquired through the analysis and simulation. The results of simulation demonstrate that the precision of Ranging may meet the requirement of engineering under the setting conditions.
