Satellite receiver module for telecommunication equipment

摘要

A satellite receiver module for telecommunication equipment includes circuitries configured to receive timing information from one or more satellites and to form timing messages based on a clock signal in accordance with the received timing information. The clock signal is a stream of temporally successive clock pulses and the pulse-rate of the clock signal is accordant with a pace indicating signal received. from a body device of the telecommunication equipment. The satellite receiver module further includes a data interface including a connector for detachably attaching to the body device and for transferring the timing messages to the body device. Because the pulse-rate, i.e. the frequency, of the clock signal is accordant with the pace indicating signal received from the body device, a high-quality local oscillator is not necessary in the satellite receiver module.

主权项

1. A satellite receiver module for telecommunication equipment, the satellite receiver module comprising:
a first circuitry configured to receive timing information from one or more satellites; a second circuitry configured to form timing messages based on a first clock signal in accordance with the received timing information, the first clock signal being a stream of temporally successive first clock pulses, the second circuitry being configured to determine the timing messages according to arrival moments of timing pulses carried by the timing information received from the one or more satellites and to count the first clock pulses at time intervals between successive arrivals of the timing pulses so as to form values for the timing messages at the time intervals between the successive arrivals of the timing pulses; a data interface comprising a connector configured to detachably attach to a body device of the telecommunication equipment and to transfer the timing messages to the body device of the telecommunication equipment; and a third circuitry configured to receive a pace-indicating signal from the body device of the telecommunication equipment and to deliver the first clock signal to the second. circuitry so that a pulse-rate of the first clock signal is accordant with the pace-indicating signal.
