Embodiment Construction
[0018] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0019] In this embodiment, in order to ensure smooth PVT calculation, it is necessary to first determine that the current BDS-2 receiver is in a normal PVT calculation state, that is, the BDS-2 receiver can continuously and stably output local PVT calculation results. After confirming that the receiver is in the normal PVT calculation state, perform PVT calculation.
[0020] Such as figure 1 , the specific process of the method for improving the PVT calculation speed of the Beidou No. 2 satellite navigation receiver of the present embodiment includes:
[0021] Step 1: Sort the satellites and traverse the satellites in order, and execute steps (1) to (3) for each satellite traversed. Wherein, sorting the satellites includes sorting according to the satellite acquisition channel number of the receiver. For example, the sequence number of the satellite captured by cha...
