four-arm spiral antenna

Details

Research on the application of four-arm spiral antenna in satellite communication and positioning

Project background

In 2020, with the successful launch of the last satellite of Beidou, it marks the completion of the global network of Beidou. The application of the Beidou system is facing an all-round outbreak, and the demand for PNT (location, navigation, time) services is growing day by day. In this context, VLG studies antennas in satellite positioning and satellite communication based on four-arm spiral technology, and has been applied in practical cases to create value for society.

Demand analysis

Target market analysis 四臂螺旋天线1 .jpg

China's public network coverage is only 30% of the territory, mountainous areas, deserts and other places are mostly non-signal communication blind areas. Frontier and Marine users: Satellite communication is the only reliable means of communication. Ground communication facilities are vulnerable: for example, communication paralysis caused by heavy rainfall in Henan. Accurate spatio-temporal location information needs: high-precision positioning applications have been integrated into all aspects of life.

Market demand

Government emergency: the number of administrative villages and natural villages in the country is huge, and the communication needs are urgent.
Marine fishing: There are about 100,000 Marine fishing vessels, and the communication demand is strong.
Tourism outdoor: self-driving tour, RV, outdoor activities and other communication needs.
Internet of Things: oil and gas production monitoring,pipeline safety monitoring, etc.
Civil-military integration: communication needs of border patrol, army, armed police, etc.
Forestry grassland: there are many forestry units, and the pastoral area is vast.
