Why Do We Need It?
We already have the US Navstar constellation, so many ask why on earth do we need to spend £2 Billion on another?
Although we do currently enjoy open access to the US system it is run and controlled by the US Military and they give no guarantees as to access in future. The use of satellite navigation systems has become vastly more widespread in recent years with marine navigation, aviation , fleet management etc all heavily reliant on the service.
If the signal was to be switched off tomorrow chaos would ensue and its is common sense to implement a system that whilst it will remain compatible with the US service, will ultimately be under EU control.
In addition, advances in technology mean that much greater positional accuracy can be offered by a new system. And of course the programme will bring many jobs to EU companies as well as removing our reliance on the US system.
