Development of GPS Positioning and Navigation Software System Based on VC++

With the rapid development of China’s economy, the field positioning and navigation technology has also been continuously developed. The global positioning system(GPS), can provide fast and accurate positioning and navigation for exploration operations in desert areas. In this paper, the developed GPS navigation and positioning software system solves the problem of cooperation between GPS user terminal equipment and exploration site. It also effectively combines image processing, data transmission, data processing, error analysis and other technologies to achieve the goals such as data recording and transmission, field navigation, data browsing and query, coordinate transformation, error analysis, and printing curve. After field test work and post-data processing, the software proved to have the following advantages: convenient operation, accurate coordinate transformation and complete functions. It could meet the requirements for accurate GPS positioning and navigation of the field exploration. Its practical effect is good and can provide reference for future field exploration and navigation mapping.
