Improved noise rejection in automatic carrier landing systems
Journal of Guidance, Control, and Dynamics, 1992A technique for reducing the effect of sensor noise in a closed-loop control system is developed. The effect of radar noise on an automatic carrier landing system is studied using digital computer simulation techniques. A noise rejection filter, which blends model estimates of the plane’s vertical velocity and acceleration with altitude information ...

A self adaptive automatic carrier landing system (ACLS)
1970 IEEE Symposium on Adaptive Processes (9th) Decision and Control, 1970This paper describes the results of a simulation study carried out to demonstrate the feasibility of a Self Adaptive ACLS. Results indicate that such a system can successfully reduce system errors due to nonlinearities and noise effects.

Automatic carrier landing systems
1974 IEEE Conference on Decision and Control including the 13th Symposium on Adaptive Processes, 1974One of the more difficult control problems of the aerospace world is that of successfully landing a flying vehicle. This problem is obviously more severe in some branches of the industry than in others, the U. S. Navy being plagued with probably the most difficult landing situation.

H-Dot Automatic Carrier Landing System for Approach Control in Turbulence
Journal of Guidance and Control, 1981The Automatic Carrier Landing System (ACLS) provides a fully automatic approach and landing capability for high-performance carrier-based fighter aircraft. Approach path air turbulence produces significant touchdown error. Using power spectral density definitions of turbulence, a method to determine flight-path deviation due to turbulence and effects ...
