BDS-3 (Part of BeiDou) has started providing global navigation services from December 2018 to nations that had signed the Belt and Road Initiative (BRI) of China. The global constellation of the BeiDou Navigation satellite system is expected to be completed in the upcoming months. Once completed, it will be able to provide lot of services such as precise point positioning (PPP), short message communication (SMP), and also can be used for international search and rescue operations globally.
