摘要
GNSS测量具有精度高、自动化、全天候、实时监测、无需通视等优点,其在电力行业变形监测领域具有广阔的应用前景。由于多频多模接收机造价昂贵,难以实现变形区域的大面积高密度布设。单频单模接收机价格低廉,可以有效降低硬件设施成本,但其易受电离层延迟等误差影像,测量精度较低。本文对北斗单双频混合变形监测算法进行了研究,并用实测数据验证该方法的可用性与可靠性。
GNSS measurement has advantages of high precision, automation, all-weather, real-time monitoring, novisibility, which impels a broad application prospect in the field of electric power industry deformation monitoring. Because of the high cost of the multi-frequency multi-mode receiver, it is difficult to realize the large area and high density layout in the deformation area. The price of the single-frequency and single-mode receiver is low, which can reduce the cost of hardware facilities effectively, but it is easy to be affected by the ionosphere delay and other error sources, the measurement accuracy is not enough to monitor. In this paper, the mixed single and dual-frequency deformation monitoring algorithm is studied, and the availability and reliability of the method are verified by the measured data.
