As the technology of the dual-mode RDSS receiver with passive and active positioning function has been developing rapidly nowadays, the high precision simulator is strongly demanded. The simulator comprises the satellite orbit module, the target trajectory calculation module, the error calculation module, and the like. The production of signal parameters has been a crucial technique that must be solved for the RDSS signal simulator. However, compared with GPS system, RDSS satellite system is a transmitting system with transponder and frequency conversion, which gives rise to more complexity in RDSS signal parameter production. Therefore, for the transmitting satellite system, signal parameter production algorithm was proposed; the formulae for the Doppler frequency shift were derived for the first time. Simulated experiments were carried out, and the results verified the validity of the algorithm.
