基于DSP 与GPS接收模块的GIS数据采集终端开发研究

With the development of science and technology, GPS global positioning system in the aerospace, aviation, marine engineering, geodesy, land navigation and other aspects more and more widely applied. But requested that the speed more and more quickly, more and more high-accuracy, real-time more and more strong. Because DSP chip running at one million instructions per second, so the embedded GPS data acquisition system related fields both at home and abroad compete to become the object of study. GIS is the original extension of the field, broaden and development. DSP and the system to be more accurate GPS receiver module to calculate and display the date, time, longitude, latitude, such as satellite information, the integration speed of the high accuracy of the past are unable to reach the hardware
