  单点定位误差
     The test result indicated that when clique value is (0.7), the single location error is over 10 meters, however when two points relative location measuring method is used, its location error is about 1.2 meter, improving its measuring precision greatly.
     试验结果表明:当阀值λ=0.7时,单点定位误差在10m以上,而用两点相对定位来测量时,其误差为1.2m左右,大大提高了其测量精度。 应用表明,在精度要求不是很高的情况下,可采用单点定位测量,在精度要求较高的情况下,可采用两点相对定位来测量。

By analyzing a lot of location measurement data of GPS, the conclusion that GPS fixed point coordinate is constitute of location excursion and normal school is drawn. In order to separate location excursion data from normal school data, normal school elimination measure and the center point calculation rule are used, and a measure of calculating the fixed point error radius in a certainty clique value is presented. Aimed at the characteristic of bigger single point location error, a new measuring method using two points relative location measurement to reduce location measurement error was put forward. The test result indicated that when clique value is (0.7), the single location error is over 10 meters, however when two points relative location measuring method is used, its location error is about 1.2 meter, improving its measuring precision greatly. The two relative location measurement method can also be used to measure ground, orientation and layout.

通过对GPS测试误差的分析,提出了GPS定点测量坐标是由位置漂移数据与正态分布数据相互叠加而成的。为了分离位置漂移与正态分布相互叠加的数据,用正态剔除法和中心点计算规则,提出了在一定阀值λ下计算定点误差半径的方法。针对单点定位误差比较大的特点,提出了用两点相对定位的测量方法来减小定位误差。试验结果表明:当阀值λ=0.7时,单点定位误差在10m以上,而用两点相对定位来测量时,其误差为1.2m左右,大大提高了其测量精度。应用表明,在精度要求不是很高的情况下,可采用单点定位测量,在精度要求较高的情况下,可采用两点相对定位来测量。这两种方法均可用在GPS的土地测量、定位和规划。
