What isBeiDou

BeiDou Navigation Satellite System (BDS) is a satellite navigation system created by China, which consists of two separate satellite constellations. The first-generation of BeiDou system, called BeiDou-1, was launched in 2000, offering limited coverage and navigation services mainly to users in China. It was decommissioned at the end of 2012, and the second generation, known as BeiDou-2 or COMPASS, was launched in December 2011 with partial constellation. Since December 2012, BeiDou-2 has provided services to customers in the Asia-Pacific region. Moreover, it is expected to offer global coverage with extended regional coverage by the end of 2020.

The Features of BeiDou Navigation Satellite System

BeiDou Navigation Satellite System was created to work as a Global Navigation Satellite System (GNSS), just like GPS, Galileo, and GLONASS. It offers a slight improvement over GLONASS in terms of accuracy and availability. However, it can be better than its competitors when additional ground antennas, signal post-processing, and communication are integrated.
