Tiantong is a Chinese geostationary communication satellite designed to provide a range of satellite communication services. It supports mobile satellite services (MSS), including satellite telephony, which allows users to make and receive calls even in areas lacking terrestrial network coverage.
With the rapid development of the shared travel industry, the disorderly expansion of shared bicycles, electric bicycles and other means of transportation has brought great pressure to urban management. In order to solve this problem, Shenzhen VLG Wireless Technology Co., LTD. (hereinafter referred to as "VLG") is committed to the development of high-precision antenna technology, through the establishment of electronic fence to achieve bicycle parking, effectively solve the problem of disorderly parking. This paper will introduce in detail the research and development achievements and application of VLG in the field of high precision antenna.
In 2020, with the successful launch of the last BeiDou satellite, the BeiDou global network was completed. The application of the BeiDou system is facing a full-scale outbreak, and the demand for PNT (positioning, navigation, and timing) services is growing. In this context, VLG studies antennas in satellite positioning and satellite communications based on four-arm spiral technology, and has applied it in actual cases to create value for society.
Integrating a GPS antenna into a shared bike or scooter is an essential component of its telematics system, enabling service providers to track and manage the fleet efficiently.
CE-GM-AGDR8639 is a G-MOUSE product consisting of an MCU main control, an MTK series dual-frequency multi-mode high-precision GNSS chip, a six-axis gyroscope inertial system and a dual-frequency antenna.
