Method for satellite-ground timing with oscilloscope

The invention provides a method for satellite-ground timing with an oscilloscope. According to the method, the oscilloscope is used for carrying out a ground experiment to obtain satellite-ground time delay delta T satellite-ground time delay, accurate satellite-ground time difference is then calculated, and satellite timing is then carried out according to the measured satellite-ground time difference to enable an on-satellite data management clock to be synchronous with a ground clock.
