China's completion of the BDS marks its major step in the race to gain market share in this potential field, alongside its US rival.
China started building its own global positioning system in the early 90s of the last century, with the aim of supporting the control of cars, fishing boats and military vehicles using map data. from your own satellite navigation system. Today, millions of mobile phone subscribers are using the system to search for places to go, give directions to taxis, or flight paths of rockets and drones.
BDS, a combination of 30 satellites, has been used to provide map data services since 2012, but only in the Asia-Pacific region. Since 2018, BDS has started to provide global reach services. About 120 countries, including Pakistan and Thailand, use BDS services to monitor water transport and direct rescue operations during natural disasters and other services.
