Behrooz Raeisy; Fatemeh Ghofrani

Volume 1, Issue 1 , September 2021, , Pages 53-64


  Various sensors can be used to attitude determination of a satellite, including the Earth Horizon Sensor. These sensors generally divided into two types: static and scanning types. In the static type, two- dimensional array or several linear arrays capture instantly the Earth image information to attitude ...  Read More
