The following paper describes the concept of an onboard time synchronization method for small satellites, as presented in the case of the Hypersat microsatellite platform. Although nowadays GPS receivers are a popular source of accurate time reference for Low Earth Orbit satellites, in our application an on-board Temperature Compensated Cristal Oscillator with an RF -link-based synchronization is also foreseen. A comparison of selected time synchronization methods is followed by considerations about their use in this application. A chosen method of time synchronization is analyzed step-by-step and expected sources of errors are highlighted. Finally, the planned development and accuracy verification method is proposed.
