Title:
ELECTRONIC APPARATUS AND GPS WEEK ROLLOVER METHOD THEREFOR, AND MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/001756
Kind Code:
A1
Abstract:
A GPS week rollover method for an electronic apparatus, a machine-readable medium, and an electronic apparatus. The method comprises: determining that a current time is within a preconfigured write time range (503); determining whether a GPS time acquired on the basis of a GPS signal received by an electronic apparatus meets a preconfigured write condition (504); and if it is determined that GPS time information meets the preconfigured write condition (505), writing a GPS week rollover processing program to the electronic apparatus (506). If it is determined that parameters such as a vehicle speed, vehicle acceleration, and a coordinated universal time meet write conditions, then a GPS week rollover processing program is written to an electronic apparatus. Introducing parameters such as a vehicle speed improves the accuracy of a time of writing a GPS week rollover processing program, and prevents directly causing week rollover when writing.
