Abstract: A passive positioning algorithm by single satellite frequency measurement based on the nonlinear optimization theory is proposed. This algorithm utilizes a series of Doppler frequency data acquired by one satellite at different places to locate the radiant points on the earth. Based on this, one Doppler frequency data preprocessing method, and one measurement error separation method based on Polynomial Autoregressive (PAR) model are also provided. Finally, the validity and accuracy of the proposed algorithm is verified by simulation results and engineering data.
