A Kinematic Single Epoch Direct Calculation Algorithm in GPS Short Baseline with Track Constraints

摘要：

　　In order to improve the kinematic single epoch positioning computational efficiency and success rate,a kinematic single epoch direct calculation algorithm is proposed in this paper when the receiver moves along a fixed track.Firstly,We can achieve initial coordinates by pseudo-range data and track constraints,then directly calculate ultra-widelane ambiguity.Secondly,we can achieve more accurate coordinates using ultra-widelane observation and track constraints,and calculate widelane ambiguity.Finally,we directly get L1 and L2 ambiguity by widelane combination,and finish the final solution using L1 and L2 observation.Experiments show a high resolution success rate in kinematic single epoch solution when the accuracy of constraints is within 30cm.
