REDUCING ERRORS IN GNSS PSEUDO-RANGE MEASUREMENTS

摘要

Polynomial regression models are used to reduce errors in measurements of pseudorange between a GNSS satellite (102) and a receiving station (104/106); 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 (102) and the receiving station; and for providing (140) usefully accurate estimates of future coefficient values of the polynomial regression models themselves.
