Paper Abstract

Low-orbit satellite ambiguity fixing is the import factor affecting GPS network difference reliability. In this paper, the satellite will be selected as reference satellite by elevation angle of satellite and barycenter of triangle to construct weight matrix. Quickly resolving double difference wide ambiguity based on wide-lane combination, fixing ambiguity of L1/L2 by LAMBDA algorithm, estimating troposphere error in non-ionosphere combination by HOPFIELD model, improving 0.3cycle float ambiguity accuracy of low elevation angle satellite, applying this method to develop network differential systems by our own intellectual property rights. The actual tests show that: accessing to the system the actual mobile station position plane accuracy is better than 5cm.
