Abstract
In a reception device using a global navigation satellite system (GNSS), both shortening of a time period until time correction and improvement of time accuracy are achieved. A reception device includes a message extraction unit, a detection unit, and a time correction unit. In the reception device, the message extraction unit extracts a message including a transmission time from a satellite signal. Furthermore, in the reception device, the detection unit detects a reception timing of a beacon signal from a ground station. Moreover, the time correction unit corrects a current time on the basis of the reception timing and the transmission time.
