METHOD AND APPARATUS FOR MODELING OF GNSS PSEUDORANGE MEASUREMENTS FOR INTERPOLATION, EXTRAPOLATION, REDUCTION OF MEASUREMENT ERRORS, AND DATA COMPRESSION

摘要

Polynomial regression models are used to reduce errors in measurements of pseudorange between a GNSS satellite and a receiving station; for data compression by replacing a large number of measurements with a small number of coefficients of the model polynomial, optionally combined with modeling residuals; for extrapolating usefully accurate estimates of future range between the GNSS satellite and the receiving station; and for providing usefully accurate estimates of future coefficient values of the polynomial regression models themselves.
