    Abstract
  • The base station of the groundbased pseudo satellite is fixed, and it lacks the fast geometric change for the static or low dynamic users. It needs a long observation epoch to solve the problem of location calculation. In order to realize the fast calculation of the precision single point positioning of the groundbased navigation system, the TIKHNOV regularization algorithm and the pseudo satellite platform of the unmanned aerial vehicle (UAV) are proposed to assist the positioning of the pseudo satellite. The simulation shows that the addition of TIKHNOV regularization can improve the positioning accuracy of ambiguity to a certain extent, and the addition of the airborne pseudo satellite platform can not only make the positioning result converge quickly, but also improve the positioning accuracy of the ambiguity floating point solution. The combination of the two can make the location algorithm achieve optimization.
