When we discussed initially these standard names in my office a few
radar guys argued there could be instrument configurations where
platform's and instrument's locations are deliberately not the same. And
as a more general approach we settled on proposing "instrument_*" names.

You are correct for vast majority of satellite instruments.

The above standard names satisfy my immediate requirements. What others
think of including the "instrument_zenith_angle" and
"instrument_azimuth_angle" or prefer to have a real-life use case first?
