Abstract
A timing signal output device includes a receiver configured to output a reference signal on the basis of satellite signals received from a plurality of positioning satellites, an oscillator configured to output a clock signal, and a processor configured to switch, on the basis of statistical value information concerning a statistical value obtained by performing statistical processing of elevation angles of the plurality of positioning satellites, a first mode for generating a timing signal based on the reference signal and a second mode for generating a timing signal based on the clock signal.
