Data playback method, receiver and terminal

The invention discloses a data playback method, a receiver and a terminal, and the method comprises the steps: analyzing real-time data to obtain simulation data, carrying out the positioning calculation through a global navigation satellite system (GNSS) receiver according to the simulation data, enabling the GNSS receiver to completely use an observation value and ephemeris information in a real-time scene to carry out the calculation processing, and enabling the real-time scene to be more accurate. The situation that the state of the GNSS receiver in the current scene cannot be completely reproduced due to the difference between different pieces of hardware is avoided; compared with the prior art, the GNSS receiver does not need to be connected with an actual antenna for signal receiving and transmitting, the analog data is used for replacement, a playback data scene of a single antenna or double antennas can be completely simulated through the analog data, hardware difference of the GNSS receiver is avoid
