-mounted clock, in addition to the user's 3D coordinates x, y, and z,Delta T refers to the time difference between the satellite and the receiver as an unknown number, and then the four unknown numbers are parsed using four equations. Therefore, if you want to know where the receiver is, you must be able to receive signals from at least four satellites. As we can see from the above, GPS is not what I originally thought. The GPS device sends a request to the satellite, and the satellite returns t
