A ground-based augmentation system (GBAS) for China's Beidou navigation satellite system is up and running.
The system - to enhance the accuracy of the Beidou Navigation Satellite System (BDS) - went live on 11 September.
The Beidou Ground Base Enhancement System - comprising 30 ground-based stations - is claimed to improve the positioning precision of the BDS to 2 cm horizontally and 5 cm vertically.
Whilst this claimed accuracy stems from tri-band real-time precision positioning technology, the system should also improve single-frequency differential navigation to 1.5 m.
China is quoted to have launched 16 Beidou satellites plus 4 experimental ones and intends to capture at least 70-80% of the now-GPS-dominated domestic market by 2020.
