Abstract
Technologies directed to a customer terminal (CT) establishing and maintaining a communication link with a satellite (SAT) in a satellite network during a Global navigation satellite system (GNSS) outage are described. One method includes establishing a communication link using position and velocity information of the CT. The method receives, at a first time, first timing information from a GNSS and updates a first clock of the CT accordingly. The method determines, at a second time after the first time, second timing information representing a clock drift between the first clock of the CT and a second clock of the SAT. The second timing information is derived from messages exchanged between the SAT and the CT prior to the second time. The method updates, using the second timing information, the first clock of the CT.
