One of the main requirements coming from different clients is to add an "anti-theft alarm" function to our gps trackers, which will trigger the loud BEEP BEEP alarm whenever the motorcyc...
At the beginning of GPS design, designers only used 10bit to characterize WN, resulting in WN only cycling between 0-1023. So GPS has an independent system for calculating date and time, measured ...
The initial GPS plan was born under the leadership of the Joint Planning Bureau, which placed 24 satellites in three orbits at an angle of 120 degrees to each other. There are 8 satellites in each...
The GPS satellite was developed by the Space Department of Rockefeller International, with a weight of 774kg and a lifespan of 7 years. The satellite adopts a honeycomb structure, with a cylindric...
After the Soviet Union launched the first artificial satellite, researchers at the Applied Physics Laboratory of John Hobbs King University in the United States proposed that since the position of...
Accurate timing: widely used in observatories, communication system base stations, and television stations Engineering construction: GPS equipment is widely used for engineering surveying in the ...
The Global Positioning System (GPS) is a medium range circular orbit satellite navigation system. It can provide accurate positioning, velocity measurement, and high-precision time standards for t...
The predecessor of the GPS (also known as the Global Satellite Navigation System or Global Satellite Positioning System) system was a transit satellite positioning system developed by the US milit...
A GPS satellite constellation consisting of 21 working satellites and 3 in orbit backup satellites is referred to as the (21+3) GPS constellation. 24 satellites are evenly distributed within 6 orb...
The task of a GPS signal receiver is to capture the signals of the selected satellites to be tested at a certain cut-off angle of satellite height, track the operation of these satellites, transfo...
