Description

technical field [0001] The invention relates to the technical field of satellite positioning, in particular to a Beidou positioning external device and a method thereof. Background technique [0002] Compared with the GPS module, the Beidou positioning module has less mass production, and has no advantages in size, power consumption and technology compared with GPS. More importantly, it has not been supported by mainstream smart phone platform vendors and has become a necessary built-in positioning module. . However, with the construction of China's Beidou system, Beidou-based satellite terminals have gained certain opportunities for development. The unique short message function of the Beidou system not only enables satellite terminals to perform navigation and positioning, but also provides communication services and enables two-way interaction. Therefore, Beidou positioning has been combined with GPS module as a multi-mode design and has been supported by some mobile ph...
