Question

Which of the following is false with respect to gimballed platform?

(a) Orients the accelerometers into a coordinate frame relative to Earth

(b) Euler angles are not easily readable from the gimbals

(c) Protect the instruments from large angular motion

(d) Protection from vibration, temperature and magnetic effects.

I had been asked this question by my college director while I was bunking the class.

This intriguing question originated from Strap Down and Gimballed Inertial Navigation Systems in chapter Satellite Radio Navigation  & Inertial Navigation of Avionics

Answer 1

Correct answer is (b) Euler angles are not easily readable from the gimbals

Explanation: One of the main purposes of gimballed system is to provide a convenient readout of vehicle attitude by reading each of the gimbals angles separately, thereby yielding convenient Euler angle outputs.
