High-precision spatial positioning optimization method based on probability of error

This thesis proposes a spatial three-dimensional positioning optimization method based on error probability, based on the positioning method based on time difference of arrival (TDOA), through the research on the positioning of substation inspection operators and equipment under complex working conditions, The method used optimizing the distance difference between the node to be positioned and different base stations can effectively improve the positioning accuracy of the staff and equipment in the station. The test results in a complex power frequency electric field environment show that the calculated results of this optimization method are better than the existing traditional positioning methods, and can effectively improve the positioning accuracy under line-of-sight conditions and realize the positioning of moving targets in the substation space.
