"基于51单片机的经济型GPS接收机设计及应用"

Design of GPS Receiver Based on 51 Single Chip Computer" is a university graduation thesis that introduces a low-cost and high-performance GPS receiver design. The GPS system developed by the U.S. Department of Defense provides continuous, high-precision three-dimensional coordinates, velocity, and time information for users on land, sea, and air around the clock. As a sophisticated navigation and positioning instrument, GPS receivers have been widely used in both military and civilian fields. The design proposed in the thesis utilizes a single-chip computer, GPS module, and a 1602 LCD display screen, implementing GPS signal extraction, display, and basic keyboard controls using C language. Practical tests have shown that this receiver can receive and display basic GPS information, achieving small size, high accuracy, continuous navigation, and can be used in various fields such as personal outdoor adventures, taxi dispatching, and maritime operations. This design provides an economic solution for a GPS receiver that meets performance requirements, making it accessible for a wider range of applications. The thesis serves as a comprehensive guide for building a GPS receiver based on 51 single chip computer, offering insights into the integration of hardware components, software development, and practical testing. Key words: GPS, single-chip computer, receiver, GR-87, LCD.
