GPS means Global Positioning System.
GPS is the abbreviation of Global Positioning System (GPS) in English, and its Chinese abbreviation is “spherical position system”.GPS is a new generation of space satellite navigation and positioning system jointly developed by the U.S. Army, Navy and Air Force in the 1970s.
GPS function must have GPS terminal, transmission network and monitoring platform three elements; these three elements are indispensable; through these three elements, can provide vehicle anti-theft, anti-hijacking, driving route monitoring and call command and other functions.
The characteristics of GPS system: high precision, all-weather, high efficiency, multi-function, easy to operate, and widely used. Application practice has proved that the relative positioning accuracy of GPS within 50KM up to 10-6, 100-500KM up to 10-7m, 1000KM up to 10-9m.
In the 300-1500M engineering precision positioning, more than 1 hour to observe the solution of the plane of its planar position error is less than 1mm, and the ME-5000 electromagnetic wave rangefinder determined by the edge length comparison, the edge length is less than 1mm. Comparison of edge length, the maximum difference in edge length is 0.5mm, the error in the calibration is 0.3mm.
The basic principle of GPS navigation system:
Measuring the distance between the satellite of a known position to the user’s receiver, and then synthesize the data of multiple satellites to know the specific location of the receiver. To accomplish this, the position of the satellite can be found in the satellite ephemeris based on the time recorded by the on-board clock.
The distance from the user to the satellite, on the other hand, is obtained by recording the time it takes for the satellite signal to propagate to the user and multiplying it by the speed of light. Due to interference from the ionosphere of the atmosphere, this distance is not the true distance between the user and the satellite, but is a pseudo-range (PR): when GPS satellites are working properly, they are constantly transmitting navigation messages in pseudo-random code consisting of 1 and 0 binary code elements.
What does GPS mean when translated into Chinese?
GPS is the English abbreviation for GlobalPositioningSystem.GPS began as a project of the U.S. military in 1958, and was put into use in 1964.In the 1970s, the U.S. Army, Navy, and Air Force jointly developed a new generation of satellite positioning system, GPS.The main purpose is to provide real-time, all-weather, and global navigation services for the land, sea, and air fields, and for some military purposes such as intelligence gathering, nuclear explosion monitoring, and emergency communications. The main purpose is to provide real-time, all-weather and global navigation services for the three major areas of land, sea and air, and for some military purposes such as intelligence gathering, nuclear explosion monitoring and emergency communications, after more than 20 years of research and experimentation, at a cost of 30 billion U.S. dollars, to 1994, the global coverage rate of up to 98% of the 24 satellite constellation of GPS has been deployed to complete. In the mechanical field GPS has another meaning: product geometry specifications (GeometricalProctSpecifications, referred to as GPS). Another meaning for G / s (GBpersecond). GPS (GeneralizedProcessorSharing) broadly processor sharing, network quality of service control in the special term.
What does GPS mean
GPS is an abbreviated form of Global Positioning System (GPS), a satellite-based positioning system used to obtain geographic location information as well as accurate Universal Coordinated Time.
The system consists of 24 satellites placed in orbit by the U.S. government.GPS provides navigation with an accuracy of up to 10 meters. It works in all weather conditions, anywhere in the world. There is no subscription or installation fee to use GPS. The system is operated by the United States Government, which is also solely responsible for its accuracy and maintenance.
