摘要
基于不同类型北斗终端的共天线零基线实测数据,从伪距标准单点定位、单频伪距相对定位以及单历元单频载波相位相对定位等方面,比较一款典型低成本导航型北斗终端与一款典型高性能测量型北斗终端的定位性能差异。结果表明,导航型北斗终端相比于测量型终端,其伪距单点定位和伪距相对定位的精度稍差,但载波相位相对定位精度差距十分明显,无法实现cm级的定位。
In this work,we compare the BDS positioning performance of a typical low-cost navigational-type terminal with a typical high-performance geodetic terminal,based on the zero-baseline data.The comparisons are carried out by pseudorange-based single point positioning,pseudorange-based single-frequency relative positioning,and carrier phase-based single-epoch single-frequency relative positioning.The results show that the positioning accuracies of the pseudorange-based single point positioning and relative positioning for the Beidou low-cost navigational terminal are slightly lower than that of the geodetic terminal,and the difference of the carrier phase-based relative positioning performances between the geodetic and navigational terminals are very significant since the centimeter-level positioning result cannot be achieved by the navigational terminal.
