Description

technical field

[0001] The invention relates to the field of electric communication, in particular to an electronic map communication device based on the GPS global positioning system and its application. Background technique

[0002] With the rapid development of communication technology, a system that combines GPS global positioning system and electronic map has appeared, and its purpose is to provide users with satellite navigation. At present, most of GPS is realized by hardware, and its expensive price has caused difficulties in application promotion. However, most of the current electronic maps are re-digitized maps that have been published, and their products are one-dimensional. Therefore, the accuracy of this electronic map is not enough. When accurate navigation is required, this electronic map cannot meet the requirements at all. Although foreign GPS products with expandable map modules have been used, their high prices and the particularity of the country's map ...
