Nobody suggested turning people down, but clearly challenging your operating ideas and concepts is something you think unacceptable. Hypocrisy per chance?
The DfT have accepted the same minima for P1 and P2 on Interim SAR and Gap SAR contracts, lower minima for P2 were used years before by BHL when S61's were in use. There has not been an issue of lesser standards or capability at any time.
Manuals say GMAP 1 is designed for short range mapping of small targets in water, less than 50 miles, using a short pulse width at a high PRF for maximum resolution to allow good definition between adjacent targets. With GMAP 2 selected the radar operates in ground mapping mode, longer pulse width and lower PRF for ground mapping / littoral use. GPS derived positions come from the several sources including OS moving map display, AIS position as well as FMS GPS EGPWS comparison with GMAP overlays. Extra GPS sources available if required. Then FLIR can enter the equation.
And yes, I agree the 189 is a bad idea and drop in capability, but a certain government minister was heard to say as long as it's a 189 for the smaller bases then the bidder has a chance.....
