New maps of Earth from reflected satnav, invented at ESA
20.9.2019 8:48
Your phone or satnav receiver routinely picks up signals from navigation satellites in order to tell you precisely where you are. But have you ever thought what happens to those satnav signals afterwards? A foresighted ESA inventor had the idea of using them as a tool for observing the Earth.

Satnav serving aircraft safely, thanks to augmentation systems
17.7.2019 9:26
Satellite navigation is useful in the air as well as on the land and sea. But stringent safety requirements mean the signals from space need to be supplemented using an additional system to be usable by the aviation sector. An international group of experts meets regularly to ensure such regional augmentation systems work together on a seamless basis.

6.4.2018 10:16
This year’s ESA–Joint Research Centre International Summer School on Global Navigation Satellite Systems is taking place in July, in the spa resort of Loipersdorf, Austria.
The 10-day course will cover all aspects of satellite navigation, up to and including the development of a potential satnav-based business.
Participants will receive a full-spectrum overview of satellite navigation, starting from the theoretical basis of Global Navigation Satellite Systems, their signals and processing by receivers, and how the final ‘position–navigation–time’ solution is worked out. On the practical side, exercises will include receiving signals from Galileo and its fellow satnav systems.
