Sorry, missed this:
In reference to the example, how many combined GPS/Inertial sensors are certified by a civil air authority for navigation?
No idea, but have seen examples of gps in lrg ins units
(Ferranti) that date back to the early nineties, so it's not exactly a
new idea. If it's not used in civil aviation, it's not because of the lack
of well proven technology.
Please tell me how. Can a purely l@ser based system provide a calibrated
airspeed? From what I understand, it can tell you how fast the air is
moving, but at 37,000ft that is pretty meaningless to the aerodynamics,
how does it sense the air density?
The first result from plugging:
"airbus laser based air speed measurement" into google:
Airspeed measured by laser | NRL Annual Report 2009
It will come, not a matter of if, but when :-)...
