| Abstract: | This paper discusses several key technique problems of pseudo satellite existed in practice.It primarily analyzes self-positioning problem of the aerial base station of pseudo satellite.The simulating calculations are carried out in two cases: when the pseudo satellite is above the ground and when the pseudo satellite is above the sea.It describes the changing rule of geometric dilution of precision with respect to the constellation distribution and devises the final positioning scheme. |

| Keywords: | satellite positioning pseudo satellite near/far field effect multi-path |
