Satellite positioning has become a vital part of our everyday lives and is key for farming, science, precise timing and emergency response. we use it in our phones, cars, planes, trains, ships and thousands of other applications.
Initially it was powered by an American system GPS or Global Positioning System a few years later a Russian system GLONASS was introduced. In 2016 Galileo the European global navigation system launched its initial services so what is Galileo and what makes it different from other constellations.
Galileo is a European state-of-the-art system that provides highly accurate guaranteed global positioning and super precise timing once fully deployed Galileo will consist of 24 operational satellites and six in orbits spares. The first Galileo test satellite, the GIOVE-A, was launched 28 December 2005, while the first satellite to be part of the operational system was launched on 21 October 2011. As of July 2018, 26 of the planned 30 active satellites are in orbit. Galileo started offering Early Operational Capability (EOC) on 15 December 2016, providing initial services with a weak signal. The complete 30-satellite Galileo system is expected by 2020. It is expected that the next generation of satellites will begin to become operational by 2025 to replace older equipment. Older systems can then be used for backup capabilities.
Galileo is autonomous but also interoperable with existing satellite navigation systems and many devices combine two or three constellations to increase accuracy and reliability while it can work with other systems Galileo is unique first of all its European and under civilian control all other systems are operated by the military so it provides Europe and European citizens with independence and sovereignty. Galileo also provides a range of new services including search-and-rescue PRS a secure service for government applications and a more precise positioning for commercial applications by offering dual frequencies as standard.
Galileo will in fact deliver new levels of real-time positioning accuracy and substantially improve availability of the service under the most extreme circumstances by deploying Galileo Europe also minimizes the risk of other navigation systems being switched off or degraded Galileo’s the result of unprecedented European cooperation and innovation to offer people across the globe a new reliable independent civilian navigation and timing system that will power limitless applications.
