SATELLITE RADIO WAVE RECEIVING DEVICE, ELECTRONIC WATCH, METHOD FOR CONTROLLING ACQUISITION OF DATE AND TIME INFORMATION, AND PROGRAM FOR THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18521433 titled 'SATELLITE RADIO WAVE RECEIVING DEVICE, ELECTRONIC WATCH, METHOD FOR CONTROLLING ACQUISITION OF DATE AND TIME INFORMATION, AND PROGRAM FOR THE SAME
Simplified Explanation
The present disclosure describes a satellite radio wave receiving device that adjusts leap second information without increasing positioning time. The device includes a receiver, one or more processors, and one or more memories for storing leap second information. The receiver retains the leap second information acquired during the acquisition operation, and the processors activate the receiver in different modes to perform the necessary processes for leap second adjustment.
- Receiver acquires information from positioning satellite radio waves
- Processors activate receiver in different modes for leap second adjustment
- Leap second information is stored in memories for future adjustments

Original Abstract Submitted
The present disclosure is provided to correctly adjust the leap second information while avoiding the increase in positioning time. Provided is a satellite radio wave receiving device including: a receiver that performs an acquisition operation of receiving a transmitted radio wave from a positioning satellite and acquiring information contained in the transmitted radio wave; one or more processors; and one or more memories in which leap second information related to a leap second adjustment may be stored, wherein the receiver retains the leap second information last acquired by the acquisition operation and wherein the one or more processors perform the following processes according to instructions stored in the one or more memories: activating the receiver in at least two modes including a first mode in which the acquisition operation is performed for continuous positioning; in the case of activating the receiver in the first mode, starting the acquisition operation without erasing the leap second information that the receiver retains and acquiring the leap second information that the receiver retains after the end of the first mode operation, and in the case where the acquired leap second information for this time is determined to be newer than the leap second information stored in the one or more memories, storing the leap second information for this time in the one or more memories; and performing a leap second adjustment for the counted current date and time, based on the leap second information lastly stored in the one or more memories.
