even though the Satellite Position can only be estimated within 50 cm with the new CryoSat2....
Until the ground processing, when it becomes sub-centimeter. Just like every other satellite before it. This kind of satellite tracking is not anything new.
That`s exactly how Hansen screwed up...till an "ignorant denier" pointed that "little problem" out...
I have no idea why Hansen got dragged into this. They seem to think he's dictator of NASA or something.
Strangely, they also seem to think those scientists are a bunch of eggheads without common sense. Rest assured, all the scientists have always understood the importance of knowing the orbit down to the centimeter, from the instant they started designing the systems.
