Abstract
Provided is a timing signal supply device that can frequently perform a phase comparison on a side of receiving a supply of a timing signal and flexibly achieve various operation modes. A GPS receiver 11 includes a baseband processing module 16 and a PN code output terminal 26. The baseband processing module 16 performs a positioning calculation based on positioning signals received from GPS satellites. The PN code output terminal 26 is configured so as to be able to output, based on the result of the positioning calculation by the baseband processing module 16, a PN code that is repeated every second in synchronization with the coordinated universal time.
Claims13
A reference signal generating system, comprising:
- a timing signal supply device;
- and
- a reference signal generation device;
- wherein the timing signal supply device includes:
- a positioning calculation module for performing a positioning calculation based on positioning signals that are received from satellites of a global positioning system;
- and
- a spreading code output terminal for outputting, based on the calculation result of the positioning calculation module, a timing signal synchronized with a predetermined timing by a periodic spreading code, said timing signal being a one-second-cycle timing signal required for time synchronization, and
- wherein the reference signal generation device includes:
- a code synchronizing circuit for being locked to the spreading code supplied from the timing signal supply device;
- a reference signal output module for outputting a signal from the code synchronizing circuit as a reference signal.
