Satellite positioning method, module and terminal based on RNSS

The invention discloses a satellite positioning method based on an RNSS. The satellite positioning method comprises the steps that a time delay value T1 of sending the nth sub-frame in a superframe from a master station to a satellite is obtained; the motion time T2 of the satellite in the period when the nth sub-frame in the superframe is sent from the master station to the satellite is worked out according to the time delay value T1; according to the coordinate value of the satellite and the speed value of the satellite in a broadcast message and the motion time of the satellite, the accurate position coordinate of the satellite is obtained through calculation. By the adoption of the satellite positioning method, the problem that due to the fact that a large deviation already exists between the utilized satellite position in the broadcast message and the actual satellite position when positioning and time service calculation by the Compass-1 satellite system are conducted, the precision of a subscriber machine is influenced is solved. The satellite positioning method has the advantages that the positioning precision and the time service precision are improved. The invention further provides an information processing module and terminal.
