摘要
载波相位模糊度固定是利用RTK精准定位无人机中的难点,为了能在高动态环境下对无人机精准定位,结合LABMDA算法的可靠性,对经典TCAR算法进行改进。改进后的TCAR算法兼顾可靠性和快速性,适用多频GNSS信号,并利用北斗数据对方法的正有效性进行检验。结果表明,提出的模糊度快速解算方法可快速、可靠地对在高动态环境下的无人机进行精准定位。
Fixing carrier phase ambiguity is a difficulty in accurately locating drones using RTK.In order to accurately locate drones in high dynamic environments,a fast ambiguity resolution method suitable for multi frequency GNSS signal positioning is proposed by combining a high reliability ambiguity resolution algorithm based on search process and a fast ambiguity resolution algorithm based on step by step rounding.The effectiveness of the algorithm is verified through Beidou data.The results show that the proposed fast ambiguity resolution method can quickly and reliably accurately locate unmanned aerial vehicles in high dynamic environments.
