Title:
METHODS AND SYSTEMS UTILIZING TRUE AIRSPEED TO IMPROVE VERTICAL VELOCITY ACCURACY
Document Type and Number:
WIPO Patent Application WO2006096226
Kind Code:
A3
Abstract:
An intertial navigation system (10) which includes a first control system (200) and a second control system (310) is described. The first control system is configured to estimate a vertical velocity (324) 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 (336) utilizing the estimated vertical velocity and airspeed (322).
