What is GPS.realtime gps tracker online Solution

　　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 the vast majority of the Earth's surface (98%). The system is developed and maintained by the US Department of Defense and can meet the needs of military users located anywhere in the world or in near-Earth space to continuously and accurately determine three-dimensional positions, motion, and time. The system includes 24 GPS satellites in space; One main control station, three data injection stations, and five monitoring stations on the ground, as well as a GPS receiver for the user end. At least 4 satellites are needed to quickly determine the location and altitude of the user on Earth; The more satellites can be received and connected, the more accurate the decoded position will be.

　　The system was developed by the US government in the 1970s and fully completed in 1994. Users only need to have a GPS receiver without additional payment. GPS signals are divided into two categories: civilian standard positioning service (SPS) and military precision positioning service (PSS). Due to the fact that SPS can be used without any authorization, the United States was originally concerned that hostile countries or organizations would use SPS to launch attacks on the United States. Therefore, errors were artificially added to civilian signals to reduce their accuracy, resulting in a final positioning accuracy of approximately 100 meters; The accuracy of military regulations is below ten meters. After 2000, the Clinton administration decided to eliminate interference with civilian signals. Therefore, civil GPS can now achieve positioning accuracy of about ten meters.

　　The GPS system has the following advantages: 24/7, unaffected by any weather conditions; Global coverage (up to 98%); High precision 3D fixed speed timing; Fast, time-saving, and efficient; Widely used and multifunctional; Mobile positioning; Unlike dual satellite positioning systems, the receiver does not need to emit any signals during use, which increases concealment and improves its military application efficiency.
