This design detailed introduces a kind of low cost and can meet the requirements of the use of performance budget GPS locator design scheme. This plan is based on 1602 single-chip computer, GPS module and liquid crystal display and other hardware, and using C language implementation of GPS signal extraction, display and keyboard control operation of basic, etc. After test, the receiver can achieve basic of GPS information receiving and display, can achieve continuous navigation, small size, high precision, and can be widely used in personal field adventure travel, the taxi positioning and maritime operations, etc.
The detailed design of a low cost and can satisfy the design scheme of economic performance requirements of the GPS locator. This scheme of MCU, GPS module and the 1602 liquid crystal display hardware based on, and realize the extraction, GPS display and keyboard control basic operation using C language. After testing, the receiver can achieve GPS information receiving and display, can be small volume, high precision, continuous navigation, and can be widely used in the field of adventure travel, personal taxi location and offshore fields.
