In 2023 satnav receivers are everywhere: in our phones, our cars, and drones, in fixed infrastructure, aboard boats, trains and aircraft. They are also in space: more than 95% of all the satellites in low-Earth orbit carry satnav receivers to calculate their position. The additional signals from Europe’s Galileo satellites are providing a big boost to the coverage, availability, redundancy, and accuracy of spaceborne receivers, in turn enlarging the possible scope of future missions, and extending the useful range of satnav much further out into space – to the Moon and beyond.
