DGPS introduction DGPS is short for English difference global positioning system, that is, differential global positioning system.
A precise known location (reference site)Install the GPS monitoring receiver to calculate the number of distance corrections between the reference station and the GPS satellite. The difference value is usually called PRC (pseudo distance correction value). The reference station
First of all, it must be admitted that this GNSS receiver is powerful and can accept GPs, GALILEO, GLONASS, BDS satellite signals,

The most important NMEA sentences include the GGA which provides the current fix data, The RMC which provides the minimum GPS sentences information, and the GSA which provides the satellite status data.
GGA-Essential fix data which provide 3D location and accuracy data.

It achieves the industry's highest level of
generated after processing by the mobile phone GPS module, and can last for several minutes. After receiving the pseudo distance data, the corresponding network processor or locating server can roughly estimate the location of the mobile phone. After necessary corrections are added to the GSM network, the positioning accuracy can be improved. (2) mobile phone GPS Positioning method. This type of mobile phone contains a full-featured GPS receiver with all functions of the mobile phone in the (1)

receiver part. The space constellation is composed of 24 navigation satellites, which is equivalent to providing 24 known space points. The ground monitoring part is used to monitor the state of the satellite and to revise the satellite orbit information. The user receiver is used to receive the satellite signal and complete the analysis and calculation of the signal to obtain the necessary navigation and positioning information.
This paper chooses the Lassen SQ/IQ series GPS receiver module of
position of the observation Point (X,Y,Z). Considering the error between the satellite clock and the receiver clock, there are actually 4 unknowns, X, Y, z and clock difference, so we need to introduce the 4th satellite to form 4 equations for solving, thus obtaining the latitude and longitude of the observation point and elevation.
In fact, the receiver can often lock more than 4 satellites, at this time, the receiver can be divided into several groups by satellite constellation Distribution,
