STANDARD SIGNAL GENERATION DEVICE, GNSS MODULE, AND STANDARD SIGNAL GENERATION METHOD
Document Type and Number:
WIPO Patent Application WO/2014/045929
Kind Code:
A1
Abstract:
[Problem] To realize, at an extremely low cost, a standard signal generation device capable of performing self-running control even when an appropriate reference signal cannot be received. [Solution] The standard signal generation device (10) is provided with: an input part (51); an oscillation part (21); a temperature sensor (25); a storage part (26); a corrective value calculation part (33); a correction part (40); and output parts (52, 53, 54). The input part (51) receives a positioning signal as a reference signal. The oscillation part (21) generates a signal having a predetermined frequency. The temperature sensor (25) acquires the temperature of the surroundings of the oscillation part (21). The storage part (26) stores the temperature characteristics of the oscillation part (21). The corrective value calculation part (33) calculates a corrective value on the basis of the reference signal or the temperature characteristics stored by the storage part (26). The correction part (40) corrects the output signal on the basis of the corrective value. The output parts (52, 53, 54) output an output signal corrected by the correction part (40).
