Method and apparatus for determining aircraft bank angle based on satellite navigational signals
First Claim
1. An apparatus for determining the bank angle of a moving aircraft comprising:
- receiver means for receiving navigational signals from satellites in orbit about the earth;
signal processing means for demodulating the satellite navigational signals;
means for determining aircraft speed based on said navigational signals;
means for determining the rate of change of the aircraft track heading from said navigational signals; and
means for determining the bank angle of the aircraft from said aircraft speed and said rate change in track heading wherein said bank angle is inversely proportional to said aircraft speed and directly proportional to said rate of change in track heading.
