Micro-Satellite Attitude Determination with Only a Single Horizon Sensor

Computer Simulation Model of Sun Sensor and Magnetic Sensor for Attitude Determination of a Small Satellite

In this article mathematical and computer models of sun sensor and magnetic sensor are considered that can be used for determination of small satellite attitude. In particular, the mathematical models of slit sun sensor and flux-gate magnetic sensor are given.

Uncooled micro-earth sensor for micro-satellite attitude control: Earth remote sensing application

Attitude Determination using Infrared Earth Horizon Sensors

Infrared Earth horizon sensors (EHS) are capable of providing attitude knowledge for satellites in low-Earth orbit, even during periods of eclipse. Attitude information is acquired by detecting Earth’s infrared electromagnetic radiation and, subsequently, determining the region obscured by Earth in the sensors’ fields of view to compute a nadir vector estimation in the satellite’s body frame. D...

(Preprint) AAS ATTITUDE DETERMINATION FOR A SMALL SATELLITE MISSION

This paper describes a path toward the development of theory for using a low noise high frame rate camera as a star tracker for spacecraft attitude estimation. The benefit of using a low noise high frame rate camera is that star data can be sampled at a faster rate while allowing one to measure very dim stars, increasing the number of stars available for attitude estimation. The development of ...

Innovation Approach Based Sensor FDI in LEO Satellite Attitude Determination and Control System

In this study Fault Detection and Isolation (FDI) in the attitude determination and control system of Low Earth Orbit (LEO) satellite is investigated. Attitude determination system uses algebraic method. This method is based on computing any two analytical vectors in the reference frame and measuring these vectors in the body coordinate system (Barishev & Krilov, 1968; Wertz, 1988). As measurin...
