Applications of GPS
The applications of GPS
Mainly for the automotive, marine, location and navigation aircraft and other moving objects. For example:
The 1 ship ocean navigation and approach
A. route guidance and approach and landing
B. vehicle navigation
C. ground vehicle tracking and the city intelligent traffic management
D. emergency rescue
E. personal travel and adventure
F. (personal communication terminal and the mobile phone, PDA, electronic mapintegrated)
2 electricity, post and telecommunications, communications network time synchronization
A. accurate time to give into the
B. accurate frequency to give into the
Geodetic 3 various grades, control measure
A. road and various line lofting
B. underwater topographic survey
C. crustal deformation measurement, the deformation monitoring of dam andlarge buildings
The application of 4.GIS
A. engineering machinery (tire cranes, bulldozers and other) control
B. fine agriculture
Application of GPS in road engineering
Application of GPS in highway construction, the key is used to create a variety ofroad engineering control network and the determination of aerial control points.With the rapid development of high grade highway, puts forward higher requirements for exploration technology, due to long lines, known to few,therefore, measured by conventional means of distribution network not only difficult, and it is difficult to satisfy the requirement of high precision. At present,the domestic has adopted GPS technology to build high-precision control network line head, and then use conventional methods laid wire encryption.Practice has proved, in the range of tens of kilometers of the position error is only about 2 cm, the conventional methods are difficult to achieve precision, but also much earlier period. Control measurements of GPS technology is also used in the bridge. Because no visibility, the network may constitute a strong shape,improve the accuracy of point, but also very effective the fulcrum of routine measurements of detection. GPS technology has a wide application prospect in the tunnel measurements, GPS measurements without intervisibility, reduce intermediate links, the conventional method therefore, fast speed, high precision,and has obvious economic and social benefits.
Application of GPS in car navigation and traffic management.
Three dimensional navigation is the primary function of GPS, aircraft, ships,ground vehicles and pedestrians can navigate using GPS navigator. Vehiclenavigation system is developed in the global positioning system GPS on the basis of a new
Type technology. Car navigation system consists of GPS, autonomousnavigation, micro processor, the speed sensor, gyro sensor, CD-ROM drive,LCD display. GPS navigation system with electronic map, the radio communication network, computer vehicle management information systems, can achieve vehicle tracking and traffic management and many other functions.
Application of GPS in the long-distance passenger vehicle management in (for example)
The first domestic professional GPS long-distance passenger vehicle management system -- Yaxon long-distance passenger GP
