Abstract

The invention discloses an error compensating method for a positioning system based on a dual-rotation laser plane transmitter network. The method provides a compensating algorithm model and designs a parameter estimation algorithm, and the main implementation steps include: (1) marking the parameter; (2) collecting compensating data; (3) collecting angle data of the point to be measured; and (4) compensating measuring equation error. The step (4) includes: a) determining a compensation factor; b) compensating the measuring equation; and c) iterating until suspension condition is satisfied, so as to solve the final result. The invention relates to large scale space coordinate measuring error compensation, solves the difficulty in systemic error marking in the dual rotation laser plane space measuring positioning system, can compensate the error item of the laser plane measuring equation and improves the systemic measuring precision.
