Abstract
An outdoor device of a timing system includes a receiver for receiving clock information from a satellite system, a processing system for running master functionality of a clock synchronization protocol to transfer the clock information to an indoor device of the timing system, and a transceiver for transferring data between the outdoor device and the indoor device. A memory device stores a fixed delay value estimating a time delay from a reception moment of a request message related to the clock synchronization protocol to a transmission moment of a reply message. There is no need to compute a difference between clock times corresponding to the reception moment and the transmission moment because the fixed delay value is used in lieu of the difference in the clock synchronization protocol. Thus, quality requirements related to an oscillator of the outdoor device can be mitigated.
