GPS satellites are suitable for climate research if the interaction
between the atmosphere and their signals is better understood.

A systematic error has been eliminated from a measurement technique
for analysing the physical properties of the Earth's atmosphere using
signals from GPS satellites – thanks to an Austrian Science Fund FWF
project. As part of this project, the radio occultation technique,
which is based on phase shifts in GPS signals, was systematically
tested for error sources. A significant error was found through a
day-night comparison of measurement data recorded over a ten-year
period. The findings have now been published along with a correction
proposal. This will make it possible to attain greater accuracy using
this method, which is set to become the future gold standard of
sensing techniques used in climate research.

First it worked for Mars, and then for other planets – for the Earth,
though, it was longer in coming: radio occultation (RO). This
technique provides information about the properties of the
atmosphere. It is based on the phase shift of radio signals caused by
the fractive index of an atmosphere.
