In the base station positioning system, complex environment will cause reflection and refraction, etc. When using ordinary TDOA positioning algorithm will lead to an inaccurate positioning result in NLOS (Non Line of Sight) environment. In order to improve the positioning accuracy, this paper introduces a TDOA NLOS error compensation interpolation positioning algorithm. In this algorithm, a TDOA NLOS error compensation model is established by using feature point to do interpolation, and use this model together with Newton iterative method to calculate the position we want. This algorithm is tested can reach meter-level positioning accuracy.
