The purpose of this paper is to improve GLONASS positioning performance in RTK-GPS/GLONASS between different types of receivers. Tables of inter-channel code biases in various receivers were obtained with a zero baseline test in order to examine the magnitude of inter-channel code bias between the receivers. We showed the improvement of fix rate and positioning accuracy of RTK-GPS/GLONASS between different types of receivers by using table of the calibrated GLONASS biases and partial ambiguity fixing solution of GPS and GLONASS for the aid of GPS carrier-phase ambiguity resolution. Furthermore, we showed that the bias correction method suggested in this paper is applicable to RTK-GPS/GLONASS with multi-epoch measurements as well as with single-epoch measurements.
