Satellite clock characterizing device, has evaluating device determining stability of movement of satellite clock or validation of time specification of clock from frequency offset, frequency drift and deviation of transmission frequency

摘要

The device has a receiving device (22) receiving a transmission signal (30) from a transmission device (18) and determining a receiving signal. The device (22) determines a receiving signal frequency and/or a phase. An evaluating device (26) determines a frequency offset, a frequency drift and a deviation of a transmission frequency of the transmission signal from the frequency and/or phase. The device (26) determines stability of movement of a satellite clock or validation of a time specification of the clock from the offset, the drift and the deviation to characterize the clock. Independent claims are also included for the following: (1) a method for characterizing a satellite clock in a satellite (2) a computer program for performing a satellite clock characterizing method.
