1. Positioning accuracy: The positioning accuracy of the Beidou locator mainly depends on the accuracy of the Beidou positioning system and the strength of satellite signals. Currently, the positioning accuracy of the Beidou positioning system is between 6 meters and 10 meters, while the positioning accuracy of the vehicle mounted GPS locator mainly depends on the accuracy of the GPS positioning system and signals. The accuracy of the global positioning system is 10-50 meters.

　　2. Number of users: Due to the active and bidirectional ranging response system adopted by Beidou, the locator and Beidou satellite not only need to receive response information from the ground control center, but also need to receive response information from the satellite. Therefore, there may be certain limitations on the number of Beidou users.

　　But the GPS positioning system uses a one-way ranging system, and positioning can be completed by simply receiving satellite signals with a positioning device. So the user limit of GPS positioning system is relatively small, but there is no need to worry too much about the user limit of Beidou. Since Beidou system was born to "snipe" GPS system, with the continuous development of Beidou system, these issues will not become problems anymore!

　　3. Coverage: The Beidou GPS locator uses Beidou for positioning. Beidou GPS is a satellite positioning system independently developed by China, and its coverage has expanded from the original "China mainland" to "Southeast Asian countries", with the future goal of global coverage; The GPS navigator uses GPS for positioning. The GPS navigation system is a satellite positioning system independently developed by the United States, with a global coverage area.
