摘　　要：在应用北斗单频接收机对矿区进行实时变形监测时,为提高北斗单频载波相位观测值预处理中周跳探测的精度,提出了基于Kalman滤波的单频北斗载波相位实时周跳探测方法,论述了粗差与周跳的识别方法。利用某矿区的北斗单频载波相位实测数据进行实验,结果表明,该方法能高效、灵敏、实时地探测出周跳发生的位置。In application of Beidou single frequency receiver in real time mining deformation monitoring,in order to improve precision of cycle slip detection in measurement preconditioning of Beidou single frequency carrier phase,real time cycle slip detection of Beidou single frequency carrier phase based on Kalman filtering was proposed,and recognition method of gross errors and cycle slips was discussed.The experiment was carried out with the Beidou single frequency carrier phase data collected in a certain mining area,the results show that the method can efficiently,sensitively and real-timely detect the location of cycle slip.
