Which of the following is false with respect to SDF floated gyros?(a)

1.	Which of the following is false with respect to SDF floated gyros?(a) Wheel is floated at neutral buoyancy(b) Used in launch vehicles(c) Three gimbals are used(d) Magnetic pickoff used to sense rotationThis question was addressed to me by my college director while I was bunking the class.I'm obligated to ask this question of Gyroscopes in chapter Satellite Radio Navigation& Inertial Navigation of Avionics
Answer» CORRECT choice is (c) Three gimbals are used To explain I WOULD say: In SDF floated gyros or single degree of freedom floated gyros, a SPINNING wheels were mounted inside a single gimbal that was floated at neutral buoyancy. A MAGNETIC pickoff was used to sense ROTATION and they were primarily used in space launch vehicles.
