The navigation for hypersonic cruise vehicle (HCV) is a challenging task because of the complex vehicle dynamic and sensor measurement noise it suffered.This paper proposes a kind of adaptive robust Kalman filter using Mahalanobis distance for HCV navigation.The innovation-based adaptive estimation is discussed first.Based on Mahalanobis distance t
The bio-optical Snowflake Embroidery Ornament Set properties of coral reef waters were examined across coral reef ecosystems not influenced by land-derived run-off, in the Great Barrier Reef lagoon (Heron Island) and the Coral Sea (the Coringa-Herald and Lihou Reefs).The aim was to determine whether the absorption properties, the concentration-spec
