BeiDou Navigation Satellite System
China successfully launched the last satellite of its BeiDou Navigation Satellite System (BDS).
The satellite, the 55th in the family of BeiDou that means “Big Dipper” in Chinese, was successfully sent into space by a Long March-3B carrier rocket.
The launch will mark the completion of the country’s domestically developed BeiDou network, one of the four global navigation networks alongside with the US’ GPS, Russia’s GLONASS and the European Union’s Galileo.
India too is building its navigational system called the Indian Regional Navigation Satellite System (IRNSS), with an operational name of NAVIC.
Navigation satellites system allow users to access high-accuracy navigation, positioning and timing as well as communication services.
