Stanley at the Time and Navigation exhibit.

A major exhibition opening April 12, “Time and Navigation: the untold story of getting from here to there,” explores how revolutions in timekeeping over three centuries have influenced how people find their way. This project is a unique collaboration between two of the Smithsonian’s largest and most popular museums: the National Air and Space Museum and the National Museum of... read more

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

IGS Launches Real-Time Service

April 2, 2013By

The International GNSS Service (IGS), a worldwide federation of agencies involved in high-­precision Global Navigation Satellite System applications, has announced the launch of its Real-­Time Service (RTS). The RTS is a global-scale GNSS orbit and clock correction service that enables real‐time precise point positioning (PPP) and related applications requiring access to IGS low latency products. The RTS is offered in... read more

Scientists in Hanoi, Vietnam, send word that on March 27 the four Galileo in-orbit validation satellites were visible at the same time in the sky over that Southeast Asian country for nearly two hours (from 2:15 to 4:00 GMT) while transmitting a valid navigation message. The research team of the NAVIS Centre at Hanoi University of Science and Technology (HUST)... read more

Making Europe’s Seaways Safe for eNavigation

28 days worth of ship-traffic data for the Strait of Dover.

An overview of the work of the General Lighthouse Authorities of the United Kingdom and Ireland on the implementation of Enhanced Loran Initial Operational Capability (IOC) in the waters around Great Britain. eLoran is the latest in the longstanding and proven series of low-frequency, LOng-RAnge Navigation systems. It evolved from Loran-C in response to the 2001 Volpe Report on GPS vulnerability. It vastly improves upon previous Loran systems with updated equipment, signals, and operating procedures. read more

Out in Front: Galileo’s World

GalileosWorldCovers-O

It’s been a long time coming. With the capability to make a position fix from four signal-broadcasting satellites, we can now say that Galileo has truly arrived. Of course, this is only one of many milestones (excuse me, kilometer markers) along the way, a trajectory that could be bounded at 23 years and counting, or possibly longer. Let’s not forget,... read more

EGNOS and Galileo Track Dangerous Goods

April 1, 2013By
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
