| Abstract: | The dual-frequency system consists of three subsystems, namely, coherent dual-frequency Doppler tracking, data transmission and telemetry. It has been widely used in the field of space flight and is still in progress. However, some parts of its theory as well as the optimum system design as shown in the paper were never seen in the published literatures. This paper gives the concept and equations about: (1). Composite (random) error of a dual-frequency range rate system resulted from the high frequency channel is in absolute predominance. (2). optimum power division and optimum design method of the dual-frequency range rate system, saving the precious satellite power or improving the range rate measurement accuracy. (3). optimum power division for a dual-frequency system for the same goal of saving power or improving the accuracy of respective subsystems. (4). the optimum design method for a dual-frequency system including a very fast and convenient graphical method. |
