ABSTRACT
With the development of society and the advancement of science and technology, GPS positioning technology is widely used in the fields of traffic navigation, navigation and aviation, geological surveying and national defense and security. This design is an online GPS positioning development system based on STM32, and one is designed based on the STM32 platform. High-precision GPS positioning system. This system is composed of STM32F407ZGT6 microcontroller, GPS positioning module, LCD display and Bluetooth module. The GPS module receives the positioning information from the GPS satellite constellation in real time and transmits the information to the STM32 chip. STM32 communicates GPS information data through NMEA-0183 The agreement is analyzed, and the positioning information obtained after processing includes longitude, latitude, altitude, speed, the number of visible GPS satellites, the number of visible Beidou satellites, the number of GPS satellites used for positioning, UTC date and UTC time, and displays these information On the LCD screen, the positioning information can also be transmitted to mobile devices such as mobile phones through the Bluetooth module. The design system can detect the GPS positioning information of the location at any outdoor location, and the position information can be viewed intuitively through the LCD screen. The detected positioning information is sent to the mobile phone via Bluetooth for more convenient storage, achieving real-time and high accuracy Degree of positioning.

Recommendations
Performance assessment of single- and dual-frequency BeiDou/GPS single-epoch kinematic positioning
The first results of the short baseline single-epoch kinematic positioning based on dual-frequency real BeiDou/GPS data are presented. The performance of the BeiDou/GPS single-epoch positioning is demonstrated in both static and kinematic modes and ...
Combined GPS and BDS for single-frequency continuous RTK positioning through real-time estimation of differential inter-system biases
Double-differenced (DD) ambiguities between overlapping frequencies from different GNSS constellations can be fixed to integers if the associated differential inter-system biases (DISBs) are well known. In this case, only one common pivot satellite is ...
GLONASS pseudorange inter-channel biases and their effects on combined GPS/GLONASS precise point positioning
Combined GPS/GLONASS precise point positioning (PPP) can obtain a more precise and reliable position than GPS PPP. However, because of frequency division multiple access, GLONASS carrier phase and pseudorange observations suffer from inter-channel ...
