Which all goes to show, it aint an easy answer!
During my tenure on the MRA4 project, there were endless calls for particular items. The answer was always that we 'wanted the Rolls Royce solution' and money was tight. We explained that it was the solution that would work and would be cheaper in the long run. 'Long run' don't count in civil service speak, this years budget is the only currency.
As it was the MRA 4 ticked all the boxes where sensors were concerned. You will therefore find all sorts of views on performance and sensors by some who know, some who think they know and others who have axes to grind, all valid views in my opinion. The solution is always a compromise after all.
I retired before the big JCB did its worst; but I still wonder what might have been. What was that book again, Dinosaurs, Donkeys and ?... must read that.
