WebAug 13, 2012 · This paper presents an automatic take-off and landing control system (ATOLS) for fixed-wing UAVs. We propose a guidance and control system to satisfy the requirement for high-precision landing using arresting wires. For trajectory tracking, Line-of-Sight (LOS)based longitudinal and lateral guidance laws are derived. WebThe longitudinal guidance and control laws were carefully designed and flight tested. Although the flight tests proved that the design satisfied all landing requirements, it identified critical parameters affecting landing performance such as vehicle longitudinal aerodynamics, navigation error, and air data sensor error.
