Schuler tuning in an inertial navigation system ensures:
A
The system ignores accelerations from aircraft maneuvers
B
Compass accuracy at the poles
C
Maximum GPS accuracy
D
The system's pendulum period matches the Earth's radius, making it insensitive to horizontal accelerations
CorrectExplanation
Schuler tuning sets the system period to 84.4 minutes (matching a pendulum of Earth-radius length), so it is not disturbed by vehicle accelerations.
