摘要

In order to position, the algorithms of three satellites and two is designed when the equation groups constituted by received satellite signals can't be solved by traditional algorithm in no light of sky. The equation groups are constituted by received signal equations and earth ellipsoid equation. The equation groups are linearized with first-order Taylor series, and the location result was solved by Gauss-Newton iterative algorithm. The measurement results based on this new algorithm were analyzed in this paper and it perfectly shows that the three satellites positioning is a good supplement to the conventional location, and the Two Satellites Positioning is a useful reference when there are no enough satellites that can be received.
