摘要
面向高动态编队飞行器相对定位的应用需求,首先介绍载波相位差分相对定位的原理;然后分析整周模糊度解算方法,采用LAMBDA方法求解整周模糊度;在相对定位解算的过程中采用了共视卫星选择策略、备用基准卫星选择策略、周跳检测与修复等策略;通过接收机的实测参数证明本文采用这些措施的有效性,能够在静-静和动-动条件实现基于载波差分的相位定位,能够达到厘米级的相对定位精度。
A high-precision method for relative positioning based on double frequency GNSS receiver is proposed to meet the demands of aerial vehicle.Firstly,the theory of carrier phase differential relative positioning is introduced.Secondly,the method of solving ambiguity which is solved by LAMBDA method is analyzed.Thirdly,a series of strategies are used in the relative high-precision positioning,such as choosing common visible satellites and backup main reference satellites,cycle slip detection and repair and so on.Finally,through the data which was received by GNSS receiver,the results show that the method is effective, which could successfully solve the relative positioning and achieve the centimeter level posi- tioning accuracy in static-static mode and dynamic-dynamic mode.
