Japan to Expand QZSS with Three Birds, Ground Control

April 5, 2013By

The Japanese government has ordered three navigation satellites from Mitsubishi Electric Corp. to expand the Quasi-Zenith Satellite System (QZSS), reports Spaceflight Now. QZSS augments GPS navigation signals for users in the Asia-Pacific region. NEC Corporation has also been awarded a contract, for the Ground Control Segment. Japan’s Cabinet Office announced the QZSS expansion on March 29, approving a $526 million... read more

EGNOS-Opener

EGNOS availability over Europe, as a precursor of Galileo globally, provides a guaranteed level of positioning accuracy in real time, for tracking vehicles transporting hazardous material. The EGNOS Open Service enhances position accuracy compared to GPS-only. The EGNOS Data Access Service further enhances accuracy and indicates the quality of the position data received from GPS. As a result of the SCUTUM project, EGNOS is now used in the operational transport of dangerous goods by road in Europe. read more
