TIMING SIGNAL GENERATING DEVICE, ELECTRONIC INSTRUMENT PROVIDED WITH SAME, AND TIMING SIGNAL GENERATING METHOD

摘要

[Problem] To enable errors in an antenna installation position or the like to be handled appropriately. [Solution] A set position storage unit stores a set position, which is the position of an antenna which receives a satellite signal, the set position being set either internally or externally. A timing signal generating unit uses a pseudo distance between the antenna and the satellite, obtained by means of a calculation assuming that the antenna is disposed in the set position, to generate a timing signal using the satellite signal received by the antenna. A determining unit determines whether it is likely, to a certain degree, that the set position represents the position of the antenna, and if is it likely to said certain degree, then the determining unit causes the timing signal generating unit to generate the timing signal on the basis of the set position, and if it is not likely to said certain degree, then the determining unit performs at least any one of timing generation stop control to stop the generation of the timing signal based on the set position, set position discarding control, and alarm generation control.
