我也百度了，也找相关资料了，但是还是不太理解。

这个嘛就是用一个位置确定点的GPS数据消除了部分误差提高精度

GPS
The term is an acronym that represents the Global Positioning System,
which is managed by the US Department of Defense to support its
navigation aid system
DGPS
The term is an acronym that represents the Differential Global
Positioning System, which is a system to improve the position fixing
accuracy by receiving the correction data with a beacon receiver for a
given GPS satellite, which is transmitted by the beacon station with a
known position
兩者是在於天線差異,DGPS是增加5M岸台校正功能,目的是要使位置更準確,以下是DGPS規格
Accuracy: 13m 2DRMS (C/A code, HDOP≦4, SA OFF)
5m 2DRMS when DGPS corrected
7m 2DRMS when SBAS corrected

精度高点而已嘛

这个问题太笼统了？哪里不理解？
DGPS的基站相当于给测量工具校‘0’.想像下千分尺。
然后你船上接收器得到的数据再加或减去之前的误差。

DGPS多个岸站。

就是比DPS的精度高点
