Design of a Longitude, Latitude and Altitude Testing System Based on Single Chip Computer

GPS is a positioning software based on receiving satellite signals, which can achieve global positioning, adapt to all climate and continuously receive signals to achieve accurate positioning. In the practical use of life, GPS is to receive the signal sent by the satellite, filter and demodulate it, and then send it to the terminal for display. Based on STC89C52RC single chip microcomputer, LCD1602 display screen and UBLOX-6M GPS module, this paper realizes a real-time measurement system of longitude and latitude, altitude and display time. It also introduces the design principle of the system in detail, analyzes the hardware composition and software design idea of the system, and finally makes the real object and carries out the hardware test. The test results show that the system function reaches the goal.
