Abstract
A method for synchronizing a time reference of a terminal clock of a terminal transceiver including an antenna and a modem, the method including: transmitting, by the modem, a terminal sync hop to a signal relay in accordance with the time reference; searching, by the modem, for a terminal sync hop return from the signal relay near an estimated terminal sync hop receive time; receiving, by the modem, the terminal sync hop return at a terminal sync hop receive time; searching, by the modem, for a master sync hop return from the signal relay; receiving, by the modem, the master sync hop return at a master sync hop receive time; calculating, by the modem, a time difference between the master sync hop receive time and the terminal sync hop receive time; and adjusting, by the modem, the time reference based on the calculated time difference.
