satellite-ground timing method for observation station without condition for compatibility test between ground station and satellite

The present invention provides a satellite-ground timing method for observation stations without any conditions for compatibility tests between ground stations and satellites. By utilizing common-view segmental arcs among observation stations, satellite-ground equipment fixed delays of observation stations without any conditions for carrying out compatibility tests are reckoned through satellite-ground equipment fixed delay of an observation station with conditions for carrying out the compatibility test, and a satellite-ground timing amount is further obtained, thus to realize a satellite-ground timing function of observation stations without compatibility tests. With adoption of the above method, the satellite-ground timing function of the observation stations on the ground is not restrained by geographic positions or task time any more; and when conditions for carrying out the compatibility tests between ground stations and satellites do not exist, the observation stations on the ground still have the timing function, thereby effectively guarantee smooth development of test and control tasks; and a satellite test and control subsystem correction sample does not need to be sent to each observation station for the compatibility test, thereby bringing convenience for smooth implementation of spaceflight test control tasks.
