| 摘 要： | 在推导罗兰C双台链交叉定位算法基础上,根据试验得到的时差测量结果进行了单台链双曲线定位、非时基交叉圆定位以及双台链交叉定位算法比较.结果表明:测量点几何因子GDOP较好时,单台链双曲线定位与交叉圆定位方法的定位结果基本相同,而GDOP较差时,交叉圆定位方法的定位结果明显优于单台链双曲线定位算法的定位结果,但两种情况下的...

| Abstract: | Based on the derivation of algorithm for double chains cross positioning,the positions of single chains hyperbolic positioning algorithm,non-time base cross circular positioning method and double chains cross positioning algorithm were compared with the measured time-difference from the experiments.The comparison shows that the positioning result of cross circular positioning method is close to that of single chain hyperbolic positioning algorithm when the geometry dilution of precision(GDOP) is good,but wi... |
