Time to Hit Warp Speed, Galileo

April 23, 2013By

Report from ENC: Constellation Needs 22 Satellites in Three Years Launch, deploy, and operate “22 satellites in less than 3 years.” That’s two satellites every three months, leading to a four-at-once launch in 2014. And that’s the challenge that Europe and the European Space Agency (ESA) now face. This pointed call to action during the opening plenary of the European... read more

GIOVE-A Uses GPS Side Lobe Signals for Far-Out Space Navigation

The European Space Agency’s (ESA’s) retired GIOVE-A navigation mission has become the first civilian satellite to perform GPS position fixes from high orbit. Its results demonstrate that current satnav signals could guide missions much further away in space, up to geostationary orbit or even as far as the Moon. GIOVE-A has been able to fix its position, velocity and time... read more

The radio spectrum is about to get even busier, as Europe’s Galileo satnav system starts services, at the same time the European Space Agency (ESA) tests novel satellite-based telecommunication services. Supporting these developments from the ground, ESA’s new custom-built Telecommunications and Navigation Testbed Vehicle will measure the resulting signals from all over Europe. Adapted from a Mercedes Benz Sprinter van,... read more

Four Galileo Birds Sighted over Asia

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

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
