Differential GPS-DGPS

On the basis of above, the technique of differential GPS (DGPS) is gradually perfected.

并在此基础上逐步完善了差分gps技术(DGPS)。

In this context, a differential GPS (DGPS) positioning, carrier phase technology emerged and rapid development.

在此背景下，差分gps (DGPS)定位、载波相位等技术应运而生并飞速发展。

Then, the troposphere pseudo-range remaining error (TDRE) of differential GPS (DGPS) is defined, its mathematical model is constructed, and the computer simulation of TDRE of DGPS is carried out.

定义了差分GPS（DGPS）的对流层伪距残差的概念，并建立了数学模型。 用计算机对DGPS的对流层伪距残差进行仿真。
