If they wanted a high resolution positioning system to cover the British isles, it could be accomplished with an entirely ground based triangulation network at a tiny fraction of the cost. Same principles, just cheaper, and a smaller area covered.
- eeh 6y agoDoes that work with GPS chips in phones? Does that facilitate research into space? Does that provide continuity for existing space research/universities? Is space research considered to be geopolitically important? I don't know the answers to these, but I do know these decisions are beyond arm chair critique.
