It is hard to overstate the importance of knowing precisely where (and when) you are and where you are going within today’s economy and society. Do you have a promising idea to improve the current positioning state-of-the-art? Then ESA’s navigation-focused NAVISP research programme wants to hear from you, before the end of March.
Many of the experts that designed and oversaw the Galileo satnav system are now supporting cutting-edge European companies in the development of new navigation technologies and services. The result is ESA’s Navigation Innovation and Support Programme, NAVISP.
NAVISP is looking into all kinds of clever ideas about the future of navigation: ways to improve satellite navigation, alternative positioning systems and, new navigation services and applications. Working in partnership with European industry and researchers, more than 200 NAVISP projects have been initiated so far.
NAVISP is divided into three elements, the first looking into improving and expanding satellite navigation, as well as establishing novel ‘positioning, navigation and timing’ (PNT) services. NAVISP’s second element focuses on innovation for competitiveness, developing all kinds of new PNT products and services. Its third element covers support to Member State priorities, including support for national testbeds and programmes.
Europe’s largest satellite constellation has grown even bigger, following the launch of two more Galileo navigation satellites by Soyuz launcher from Europe’s Spaceport in French Guiana on 5 December. Galileo satellites 27-28 add to an existing 26-satellite constellation in orbit, providing the world’s most precise satnav positioning to more than 2.3 billion users around the globe.
The launch of Europe’s latest Galileo satellites has been postponed. Launch operations were interrupted at H-10 minutes due to adverse weather conditions (lightning). The Soyuz launch vehicle and satellites are in a stable and safe condition.
The launch of Europe’s latest Galileo satellites is now scheduled for the night of 4-5 December.
Galileo satellites 27 – 28 lifted off by Soyuz launcher VS26 from Europe’s Spaceport in French Guiana at 01:19 CET on 5 December (4 December at 21:19 local Kourou time). Follow the launch live on ESA Web TV Two.
Europe’s latest Galileo satellites will be launched on the night of 3-4 December. Arianespace has taken the decision to begin fuelling their three-stage Soyuz launcher.
The launch of Europe’s latest Galileo satellites is now due to take place tonight, very early on Friday morning. The original launch date was postponed due to adverse weather conditions at the launch site.
Due to unavailability of a downrange tracking station, Arianespace has taken the decision to postpone the fueling of Galileo's three stage Soyuz launcher. The VS26 Soyuz launch vehicle and the satellites are in a stable and safe condition.
The earliest launch date for Europe’s latest Galileo satellites is now during the night of 3-4 December.
Europe’s Galileo satellite navigation system is providing the world’s most precise positioning services, but the satellites at its heart are surprisingly compact, and dependent on many different technologies to keep running. Here are 12 things you probably didn’t know about them:
Europe’s next pair of Galileo satellites have been given a green light for launch. Last Friday’s Launch Readiness Review confirmed that the satellites, the supporting ground installations, and the early operations facilities and teams are ready for lift-off on the early hours of Thursday morning, European time.
UPDATE: GALILEO LAUNCH NOW SCHEDULED FOR 3 DECEMBER AT 0127 CET (2 DECEMBER 2127 KOUROU TIME)

Last Friday’s Launch Readiness Review confirmed that the satellites, the supporting ground installations, and the early operations facilities and teams are ready for lift-off on the early hours of Thursday morning, European time.
Soon another pair of Galileo satellites will be launched on top of a Soyuz from Europe spaceport in French Guiana. These satellites are the first of the so-called 'Batch 3', comprising of 12 additional first-generation Galileo satellites commissioned in 2017 to bring the constellation to full operational capability. They will be used to further expand the constellation up to 38 satellites and act as backups and spares for satellites that reach their end-of-life.
This 11th Galileo launch also marks the 10 year anniversary of the first launch of the Galileo operational satellites and the start of the construction of the constellation. Ten years later Galileo is the most accurate satellite navigation system in the world and available on every recent smartphone and device. It is also two decades since satellite navigation was first introduced as a completely new activity in the European space sector.
Meanwhile ESA continues to ensure the future of the Galileo programme and European expertise in satellite navigation. For Galileo ESA has already commissioned a second generation of more powerful and flexible navigation satellites while new services are being developed to meet market demand.
Europe’s next two Galileo satellites have been attached to the dispenser on which they will ride to orbit, and the launcher fairing that will protect them during the first part of the ascent to orbit has been closed around the pair.
Europe’s first prototype satellite for Galileo, GIOVE-A, has today been formally decommissioned after 16 years of work in orbit. The 2005-launched mission secured Galileo’s radio frequencies for Europe, demonstrated key hardware and probed the then-unknown radiation environment of medium-Earth orbit.
A significant first for next month’s 11th Galileo launch: thanks to an upgrade of the world-spanning Galileo Control Segment, this will be the first launch where the satellites ‘ first steps into space will be overseen from an existing Galileo Control Centre, rather than requiring an external mission control site.
Europe’s own satellite navigation system, Galileo, has become the world’s most precise, delivering metre-level accuracy, available anywhere on Earth. It is also saving lives, relaying distress calls for search and rescue. Today there are 26 Galileo satellites in orbit 23 222 km over our heads; the first of them were launched on 21 October 2011, with nine more launches in the following years. The satellites in space are supported by a globe-spanning ground segment. The system as a whole is set to grow, with the first of 12 ‘Batch 3’ about to join the current satellites in orbit and new ‘Galileo Second Generation’ satellites in development.
Galileo has been financed by the EU and developed by ESA, with services delivered by EUSPA.
The latest pair of Galileo satellites have touched down at Europe’s Spaceport in French Guiana, ahead of their launch together next month.
An experimental satellite navigation receiver station high atop Spain’s Mallorca island has opened up a novel view of the ever-changing face of the sea. By picking up satnav signals from the far horizon as they bounce off ocean waves, the receivers are able to measure sea surface height down to a scale of centimetres.
As work proceeds on Europe's Galileo Second Generation satellites, the European Space Agency is pleased to announce the Galileo Second Generation Industry Day 2021 online event on Tuesday 7 September.
The first Galileo Second Generation hardware has begun testing, with test versions of the satellites’ navigation payloads undergoing evaluation by Airbus Defence and Space at their Ottobrunn facility in Germany and by Thales Alenia Space at ESA’s ESTEC technical centre in the Netherlands.
Busy urban centres represent key areas of demand for satellite navigation services, but dense concentrations of high buildings mean that satnav signal reception may sometimes fall short. So ESA is issuing a call for ideas to make up for such service gaps through the use of imaging and 3D mapping technology – ahead of a dedicated workshop on 6 July.
