This article is addressed to the systematic errors compensation stipulated due to non-identical satellite constellation. This method is applied to autonomous GNSS receiver solutions in respective mode. Compensation method is based upon linear relation of the linear estimated vector solutions residuals between partial and whole values set and the estimated residuals for the universe. Examined method is available for the remote receiver to exclude the contribution of the untracked (in the remote receiver) satellites from the received master station navigation solution. Due to the slow autonomous solution component spatio-temporal fluctuation, which caused by pseudorange measurement systematic errors, the correction would be uplinked from master to remote user having transmission rate less then one-s for actual estimated coordinates. Flight tests highlighted successful compensation of the systematic errors caused by non-identical navigation satellite constellation by means of the method discussed. The test results have confirmed sub-meter precision for the respective navigation by using autonomous pseudorange solutions.
