METHODS AND SYSTEMS UTILIZING TRUE AIRSPEED TO IMPROVE VERTICAL VELOCITY ACCURACY

METHODS AND SYSTEMS UTILIZING TRUE AIRSPEED TO IMPROVE VERTICAL VELOCITY ACCURACY

An inertial navigation system which includes a first control system and a second control system is described. The first control system is configured to estimate a vertical velocity based in part on received vertical acceleration data. The second control system is configured to receive the estimated...

Zusammenfassung:An inertial navigation system which includes a first control system and a second control system is described. The first control system is configured to estimate a vertical velocity based in part on received vertical acceleration data. The second control system is configured to receive the estimated vertical velocity from the first control system and determine a compensated vertical velocity utilizing the estimated vertical velocity and airspeed.
