Abstract
A timing signal output device includes a timing signal generation circuit which generates a timing signal synchronized with a reference signal based on a satellite signal received from at least one positioning satellite, the timing signal being synchronized with the reference signal at a timing based on an elevation angle of a positioning satellite.
Claims10
A timing signal output device comprising:
- a timing signal generation circuit configured to
- receive a reference signal based on a satellite signal received from at least one positioning satellite,
- receive elevation angle information of the at least one positioning satellite, and
- generate a timing signal synchronized with the reference signal at a timing using a correction coefficient that is based on an elevation angle of the at least one positioning satellite, wherein the correction coefficient defines a relationship between a delay time and the elevation angle, by correcting the timing of the synchronization of the timing signal with the reference signal using the elevation angle information.
