| Abstract: | First introduces the POS system positioning principle and the principle of precise point positioning(PPP), the mathematical model,and then combined with Hunan Province six vehicles helicopter aerial inertial navigation trajectory data obtained,through the precise point positioning and base station later difference comparison of numerical results and positioning precision analysis,the results show that the precise point positioning relative to the base station later more differential positioning in a horizontal direction,vertical direction can achieve relative accuracy of about 10 cm,respectively. It provides useful reference for the base station aerial photography in difficult areas. |
