"The other aspect of military usage is more redundancy is better ( China is developing anti-satellite warfare hardware )."
While redundancy can be useful, it also increases complexity. There are so many if's and but's in this is it hard to know where to begin. Basically it feels like someone aw the word satellite on for sale notice and said, that will do.

"If Britain and her allies have access to a less accurate system which has hundreds of cheap satellites, it would be much harder to take it out than the existing GNS systems which have a handful."
I'm not sure Britain ha any allies left. An inaccurate GPS system is an oxymoron
"Even if the resolution isn't perfect - an ICBM missing by a few feet is still going to knacker whatever it was aiming at."
ICBM's are quite happy using inertial navigation and star tracking technology. Your smart missile designed to hit a small bunker window is less resiliant ti inaccracy
