It would be far too inaccurate. They obviously don't need three independent tracking systems on ICEsat. They can get by with much less precision for its particular purposes.

All raw satellite data is adjusted to take into account errors as described in previous post.

The frequency of the altimeters on satellites cannot be anymore accurate than about 100mm.

Bullsh1t. Where's the GPS on ICEsat? There isn't one.

So anyway to summarise your points, the oceans are warming and bulging, as described by Ed Caryl? Right?

Excessive warming causes bulging hmmmm.

No its not bullsh!t....!!!!!!!

The frequency on the altimeters is only accurate to about 100mm.

All raw data on satellites has to be adjusted to correct for errors.

So the main reason sea levels are rising is because of thermal expansion....???

Then what's all the baloney about melting glaciers and the arctic...???!!

Yes it is. By the way, millimetres is not a unit of Frequency. You do know that?

I don't know. Did you post that somewhere - that the main cause of sea level change in the last 50 years has been glacier meltwater? I usually catch most of your baloney but must have missed that particular gem.

Can you provide a link to where you posted it so that I can have a good laugh?

Frequency is measured in Hertz.

Sure I know its measured in hertz, but the frequency is then converted to a measurement.

The angle of the satellite, the frequency travelling through water vapour, and maybe disturbed by other signals, the suns radiation, cosmic rays.

Al these things affect the frequency when its travelling through the atmosphere.

And therefore the reading will be out by about 100mm.

Sounds like a Willy Soon type "therefore".

Cosmic Rays affect the frequency ?
The Sun's radiation affects the frequency?
Other signals? You mean like TV Shows and stuff?

How does that work? Isn't it pulse modulated?

The pulse or frequency still has to travel through our atmosphere and encounter all this other phenomenon.

Of course it will be affected.

You didn't answer. OK, I'll assume that you mean that Cosmic Rays affects the frequency by magic.

All physical elements will affect the frequency.

Water vapour
Radiation from the sun
Cosmic rays
Clouds
Wind
Angle of satellite

Why wouldn't they affect the frequency....???!!!!
