Description

Technical Field

[0001] The utility model relates to the technical field of Beidou terminal equipment, in particular to a card-connected vehicle-mounted Beidou host. Background Art

[0002] The BeiDou Navigation System (BDS), officially known as the BeiDou Navigation Satellite System (BDS), is a global satellite navigation system independently developed by China. Along with the US's GPS, Russia's GLONASS, and the EU's Galileo, it constitutes one of the four major global satellite navigation systems. The BDS is designed to provide high-precision positioning, navigation, and timing services to users around the world, 24 / 7. An on-board BeiDou host refers to a BeiDou satellite navigation system terminal device installed in a vehicle, utilizing China's BeiDou Navigation Satellite System (BDS) to provide positioning, navigation, and tracking services.
