Abstract
The embodiment of the invention provides a satellite clock error determination method and device, a program product and a storage medium. The method comprises the following steps: determining site information of a ground monitoring station based on N groups of first navigation data sent by N first satellites; obtaining orbit information of a second satellite, wherein the orbit information of the second satellite is used for representing a motion trail of the second satellite; and determining a target clock difference based on the site information, the orbit information of the second satellite and second navigation data sent by the second satellite, wherein the target clock difference is used for representing the difference between the site clock of the ground monitoring station and the satellite clock of the second satellite. According to the method and the device, the problem that the satellite clock error cannot be accurately calculated in the prior art is solved, and the effect of accurately calculating the satellite clock error is achieved.
