title = "Research on fast RTK GNSS algorithm based on partial ambiguity resolution",
abstract = "The key of GNSS RTK algorithm is the fast and reliable double difference integer ambiguity resolution. Currently widely used algorithm is the LAMBDA method based on the ambiguity search algorithm. But the search efficiency of LAMBDA method is gradually reduced with the increase of the degree of ambiguity. While multi-system compatible positioning is the trend of the GNSS development, the double difference ambiguity dimension is bound to increase significantly, thus reducing the search efficiency of the LAMBDA method. This paper puts forward a resolution in which dividing the ambiguity into different groups which is sorted by the elevation. First fix higher elevation ambiguity, and then to part of the ambiguity. Thus speeding up the ambiguity search efficiency. Based on the data of GPS and BeiDou system, this paper proves that this algorithm can improve the efficiency of the ambiguity resolution.",
