Abstract

Described herein are a system and method for compensating for antenna phase center and SNR variation in dual- and multi-antenna GNSS receivers. Satellite signals are received at a GNSS receiver having a plurality of antennas including a first antenna and a second antenna. GNSS measurements are collected based on the received wireless signals using the first and second antennas. A horizontal orientation of the plurality of antennas with respect to a transmitting satellite is estimated. One or both of an antenna phase center correction and an SNR correction are obtained from one or more calibration tables based on the horizontal orientation. A geospatial position of the GNSS receiver is estimated using the GNSS measurements and one or both of the antenna phase center correction and the SNR correction.
