Abstract
A method and apparatus for synchronizing the oscillators onboard satellites of a same network, while minimizing relativistic effects. The method consists of identifying a reference signal having minimal Doppler frequency shifting; adjusting the frequency of an ovenized oscillator to the minimally shifted reference signal, and repeating the process for all satellites of a satellite train having a similar orbital path. Subsequently, the clocks on board the satellites of a same train can be set to a same time, by relaying a clock synchronization protocol between the satellites. The method includes a number of error measurement techniques allowing to further compensate for relativistic effects and make further corrections over time.
