Description
Technical field
The present invention relates to the tracing and positioning apparatus field, relate in particular to and a kind ofly utilize known general Global Positioning System (GPS) to carry out the equipment of tracing and positioning.
Background technology
GPS (Global Positioning System) hereinafter referred is GPS.Briefly, this be one by 24 satellite systems that satellite is formed covering the whole world.This system can guarantee at any time, a bit can observe 4 satellites simultaneously arbitrarily on the earth, can collect the longitude and latitude and the height of this observation station to guarantee satellite, so that realize functions such as navigation, location, time service.This technology can be used for vector aircraft, boats and ships, vehicle and individual, and safety, exactly along selected route arrives punctually at the destination.
GPS (GPS) is the of new generation Aerospace Satellite navigation positioning system of the seventies in 20th century by U.S. land, sea, and air joint research and development.Its fundamental purpose is for three big fields, land, sea, air provide real-time, round-the-clock and global navigation Service, and is used for some military purposes such as information acquisition, nuclear blast monitoring and emergency communication, is the important composition that the U.S. dominates global strategy exclusively; Through the research experiment in surplus 20 years, expensive 30,000,000,000 dollars, in March, 1994, global coverage rate was laid up to 24 gps satellite constellations of 98% and has been finished; The GPS Global Positioning System (GPS) is made up of three parts: space segment---the GPS constellation; Ground Control part---ground monitoring system; Customer equipment part---gps signal receiver.
The GPS location technology has high precision, high-level efficiency and advantage cheaply, makes it in the reinforcement transformation and the foundation of all kinds of geodetic surveyings control nets and obtained using comparatively widely in the deformation measurement of road engineering survey and macrostructure thing.。
The GPs satellite positioning tech is applied in road guide widely at present, especially be applied on the vehicles, general all is the antenna that installing can receive positioning satellite signal on the vehicles, and one positioning satellite signal can be translated into through, the main frame of latitude and altitude information, in main frame, also include a mobile phone, this mobile phone can with through, latitude and altitude information are sent to control center by short message, this control center be a kind of can with through, latitude and altitude information cover are used on the map, and notify the paying mechanism of the present position of user by mobile phone via the attendant, and the user of known use GPs positioning system, all be object tracked and that inform, and can't directly obtain the located in connection data.
If the missing old man of individual regular meeting, child or pet are arranged in the man today; also positioning system help is via satellite looked for; we are only by medium such as newspaper, advertisement, networks; ask other people to assist to look for, wherein, quick with Internet communication again; if we are can be with GPs and network combination; convert passive homing to initiatively tracking, can find missing old man, child or pet fast, or even stolen vehicle.
Be called as Chinese invention patent publication number " CN2886597 " name " addressing satellite locator " patent disclosure a kind of tracking, training use the GPS steady arm, a kind of addressing satellite locator, it includes: a housing; One circuit board is arranged in the described housing, and is preset with the antenna that can receive/transmit on this circuit board; One satnav (GPS) module is arranged on the described circuit board, and The built-in has the satellite antenna that receives positioning satellite signal, the satellite-signal that receives can be converted to through data such as, latitude, speed, distance and height; One wireless network (WI-FI) module, be arranged on the described circuit board, The built-in has a fixing network communication address, receive/send out the fixed network communication address by wireless network base stations, utilize Internet device and the online person of this network communication address, can obtain the data such as warp, latitude, speed, distance and height of satnav (GPS) module.This kind followed the trail of, the GPS steady arm use in training, and combining of location and wireless network just can utilize the network tracking to hold the present position of addressing satellite locator person via satellite, reaches and monitors the merit that whereabouts do not have distance; But this kind followed the trail of, training has only by computer with the GPS steady arm and reads data on the GPS tracker, and the Google Maps of networking again just can view the whereabouts of tracker.Therefore do not have the real-time tracing function, and can't utilize this kind tracing and positioning equipment to carry out real-time communication.
