Title:
COMPRESSION METHOD AND RECONSTRUCTION METHOD FOR GPS DATA, AND GPS TERMINAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/103307
Kind Code:
A1
Abstract:
The present invention provides a compression method and a reconstruction method for GPS data, and a GPS terminal apparatus. A compression method for GPS data comprises the steps of: receiving, by a GPS terminal apparatus mounted on a moving object, coordinate values related to source data of global positioning system (GPS) information at a sampling rate according to a communication environment which allows communication with an external apparatus in a specific band; assigning data capacity matching a maximum value of a displacement according to a difference between coordinate values which can be generated by the moving object; calculating a displacement value between corresponding coordinate values at every time interval of the sampling rate; and generating displacement data by encoding each displacement value according to the data capacity, and storing the same in a predetermined apparatus.
