A method for synchronizing a time of day clock of a clock system is disclosed. A portable satellite timing system receives a satellite signal when at a first location and generates a time of day signal. The portable satellite timing system is then transported to a second location, where the satellite signal cannot be reliably received, and coupled to the clock system. The portable satellite timing system transfers the time of day signal to the clock system. Concurrently, the clock system receives a communication signal from a communication system and recovers a clock signal from a communication signal. The clock system synchronizes the time of day clock based on the time of day signal and the clock signal. The disclosed method advantageously synchronizes the time of day clock located in a structure without having to install a satellite antenna on the outside of the structure. |
