摘要
采用转动基线的方法解决利用“北斗”卫星载波相位进行定向的关键技术问题——初始相位整周模糊度的确定,并进行了仿真实验,结果表明:当原始载波相位观测精度优于2％周时,利用2m基线在5min时间内可达到方位0.01°的定向精度.
This paper has developed an approach of rotating the baseline to solve the key technical problem lying in the process of orientation determination by Beidou satellites' carrier phase-identification of the original phase integer ambiguity, and the simulation result shows that the azimuth determination precision of 0.01° by a 2-meter-long baseline during 5 minutes can be achived when the non-difference phase measurement precision is better than 2 percent of a cycle.
