Global Navigation Satellite Systems Engineering, Policy, and Design
Precision agriculture is just one of many sectors taking advantage of advancements in GNSS technology in recent years, but few have the potential to make such a big impact.

With plenty of promise, the third launch of Europe’s Galileo constellation took place four years ago. What followed was not at all what was expected, as problems turned much of the promise into gloom.

The Galileo constellation took another big step towards full operational capability with the successful launch last month of four satellites on-board an Ariane 5 launcher. Representatives of leading industry that have adopted Galileo then held a special press briefing for journalists from across the continent to address updates on how European citizens and businesses are already taking advantage of benefits delivered by Galileo.

The European Space Agency (ESA) recently ran an internal competition for its trainees to develop an app capable of making positioning fixes using only Galileo satellites. ESA challenged these young graduate and national trainees to develop smartphone apps to perform satellite navigation fixes solely with the use of Galileo satellites. Three teams developed apps in their spare time, presenting their results to a jury of experts from ESA, the European Global Navigation Satellite Systems Agency (GSA) and Google.

The UK seems well and truly on the path to leaving the European Union. The implications for the Galileo program are still unclear, and won’t be known until Brexit negotiations are completed, at the earliest.

The Cospas-Sarsat MEOSAR (Medium-Altitude Earth Orbit Search and Rescue) system has been in the news quite a bit of late, and with good reason. As the technology has evolved, so too has the ability to improve search and rescue operations which save lives.
The cover story for the current issue of Inside GNSS is dedicated to the Cospas-Sarsat MEOSAR system and its role as a solution to support the ICAO GADSS Autonomous Distress Tracking recommendation.

Today, it appears that the Cospas-Sarsat MEOSAR system, relying on payloads deployed on GNSS constellations (Galileo, GPS, GLONASS), offers all the conditions to meet the new recommendation of ICAO for ADT-system for Commercial Aviation, with a new generation of in-flight triggered beacons, identical to the current ELT in terms of aircraft integration, but capable of receiving triggers and cancellation events from the avionics, from the crew or from internal sensors, and of detecting and managing their inhibitions to maintain the capability to raise alerts and be localized in any situation.

Yet another milestone has been reached as the Galileo global navigation satellite system inches closer to completion of its entire constellation comprising of 24 operational satellites plus spares in three orbital planes as the last two Galileo satellites of the second tranche were sent to Kourou on May 31.

Orolia announced today that its atomic clock solutions have been selected for the Galileo Global Navigation Satellite System (GNSS). Under contracts totaling 26 million euros, or approximately $30 million, Orolia will deliver its stable, accurate timing solutions to 12 additional Galileo satellites.

This article focuses on the research project Galileo Online: GO! – which with support from the Federal Ministry for Economic Affairs and Energy (grant number 50NA1510) designs and develops a reliable and high-precision receiver for multi-constellation and dual-frequency GNSS whose suitability and capabilities are tested in railway applications. Project results showcase the advantages of GPS and Galileo if used simultaneously in railway applications.

The European GNSS Agency (GSA) hosted the second Fundamental Elements Info Day on March 14, 2018, welcoming 55 participants from 38 organizations to its headquarters in Prague. The info day focused on upcoming FE (Fundamental Elements) funding opportunities and provided a status update on the funding program.
