The stable platform's job is to keep accelerometers what?

• A. Remain level relative to Earth's surface
• B. Become heated during flight
• C. Receive GPS corrections
• D. Record engine thrust

Answer: (A)

A stabilized platform keeps the accelerometers oriented relative to the Earth's surface, staying level as the vehicle moves. This matters because accelerometers measure forces along their axes, and if the platform tilts, gravity’s pull shifts on those axes, making readings appear as if the vehicle has acceleration even when it doesn’t. By actively counteracting rotational motions, the platform maintains a fixed reference frame so the accelerometers measure true translational accelerations rather than artifacts of attitude change. This stable orientation is essential for accurate navigation data. The other options don’t relate to how the platform stabilizes sensor orientation.
