SATELLITE RECEIVER MODULE FOR TELECOMMUNICATION EQUIPMENT
First Claim
1. A satellite receiver module for telecommunication equipment, the satellite receiver module comprising:
- a first circuitry for receiving timing information from one or more satellites,a second circuitry for forming 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,a data interface comprising a connector for detachably attaching to a body device of the telecommunication equipment and for transferring the timing messages to the body device of the telecommunication equipment, anda third circuitry for receiving a pace indicating signal from the body device of the telecommunication equipment and for delivering 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.

Abstract
A satellite receiver module (101) for telecommunication equipment includes circuitries (102, 103) 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 (110) of the telecommunication equipment. The satellite receiver module further includes a data interface (105) including a connector (106) 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.
