PROBLEM TO BE SOLVED: To provide an autonomous telemeter device capable of securing accuracy of an internal clock while maintaining ON/OFF of a power source of a GPS antenna and a GPS receiver.SOLUTION: The autonomous telemeter device includes: a GPS receiver 2 for acquiring a GPS time; a GPS antenna 1; a relay switch 10 for turning on/off the power sources of the GPS receiver and the GPS antenna; a timer 9 for controlling the relay switch 10; and an internal clock 3 for calibrating the time by using the GPS time. The timer 9 includes an autonomous telemeter device 100 for determining a timing of turning on the first relay switch 10 on the basis of the accuracy of the internal clock 3. |
