GPS精度因子(GDOP,PDOP,HDOP,VDOP,TDOP)-CSDN博客
2018年12月12日 · 在GPS导航和定位中,我们使用几何精度因子(DOP,dilution of precision,也翻译为精度衰减因子)来衡量观测卫星的空间几何分布对定位精度的影响。 DOP分为以下几种: PDOP ( position dilution of precision ) 三维位置精度因子:为纬度、经度和高程等误差平方和的开 …
What is PDOP? - agsgis.com
2017年3月15日 · When satellites are evenly spread throughout the sky, their geometry is considered strong (lower DOP value). Thus, the more satellites available spread evenly throughout the sky, the better our positional accuracy will be (and the lower the PDOP value).
DOP、PDOP、PDOP限制,一篇详解 - 知乎
PDOP,英文全称Position Dilution of Precision,译作“空间位置精度因子”,空间位置精度因子是一个表示用户位置误差和卫星位置误差之间关系的无单位数字。 PDOP值为纬度、经度和高程等误差平方和的开根号值。 反映定位精度衰减的因子与所测卫星的空间几何分布有关,空间分布范围越大,PDOP 值越小,定位精度越高,一般小于3为比较理想状态;反之,PDOP 值越大,定位精度越低。 3、PDOP限制. PDOP限制顾名思义就是接收机计算位置的最高 PDOP 值。 4、RDOP. …
