Project Background
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.
Demand Analysis
Target market analysis
China’s public network coverage area is only 30% of the country’s land area, and mountainous areas, deserts and other places are mostly blind spots with no signal communication. Border defense and maritime users: Satellite communication is the only reliable means of communication. Ground communication facilities are fragile: For example, heavy rainfall in Henan caused communication paralysis. Demand for accurate spatIOTemporal location information: High-precision positioning applications have been integrated into all aspects of life.
Market demand
Government emergency: There are a large number of administrative villages and natural villages in the country, and the communication needs are urgent.
Marine fishery: There are about 100,000 marine fishing vessels in the country, and the communication needs are strong.
Tourism and outdoor: Communication needs such as self-driving tours, RVs, and outdoor activities.
Internet of Things: Oil and gas production monitoring, pipeline safety monitoring, etc.
Military-civilian integration: Communication needs of border patrols, the military, and armed police.
Forestry and grassland: There are many forestry units and the pastoral area is vast.
