Other applications of GPSIn addition to GPS for navigation, positioning, measurement, the GPS satellite system space contained accurate clock time and frequency information can be released, therefore, the accurate clock space satellite based on the ground control station, the precise time and frequency of transmission is another important application of GPS, application of the control function for precise time or frequency, engineering experiments for many services. In addition, GPS can also use the meteorological data obtained, some experiments and engineering applications.The global positioning system GPS is the development of this year one of the most high-tech pioneering, its global, versatile, navigation, weather all day long timing, speed advantages will be more and more widely used in many fields. In developed countries, GPS technology has been applied in transportation and traffic engineering. At present, the application of GPS technology in China road engineering and traffic management has just started, with the development of Chinese economy, research and application of high grade highway construction and the rapid GPS technology gradually thorough, its application in road engineering will be more extensive and in-depth, and play a bigger role.
Application of GPS in road engineeringApplication of GPS in highway construction, the road works mainly for the establishment of control network and the determination of aerial control point. With the rapid development of highway, puts forward higher requirements for the survey, due to long lines, few points to know, therefore, measured by conventional means of distribution network not only difficult, but it is difficult to meet the requirements of high precision. At present, China has adopted GPS technology to establish high-precision control network line head, encryption and then use conventional methods laid wire. Practice has proved that in the range of tens of kilometers of the position error is only about 2 cm, to conventional methods is difficult to achieve the accuracy, but also greatly advance the control measure the duration of.GPS technology is also used in large bridges. Because no visibility, can constitute a strong network, improve the precision of point at the same time, the fulcrum of routine measurements of detection is also very effective in.GPS Technology It has a wide application prospect in tunnel measurement, GPS measurement no visibility, reduce intermediate links, so the conventional method, high speed and high precision, which has obvious economic and social benefits.
