In-Flight Alignment Using H∞ Filter for Strapdown INS on Aircraft

The Scientific World Journal, 2014
In-flight alignment is an effective way to improve the accuracy and speed of initial alignment for strapdown inertial navigation system (INS). During the aircraft flight, strapdown INS alignment was disturbed by lineal and angular movements of the ...
