Abstract

It is necessary at least two or more independent known vectors for attitude determination of an artificial satellite. One of these vectors can be the Earth Magnetic Field, which is used as reference in navigation for centuries. Other reference can be the sun, which is easily distinguished of other astronomical objects in the proximities of the Earth. While the Earth Magnetic Field can be measured by a small solid-state three-axis magneto-resistive transducer, the own photovoltaic system of the artificial satellite can provide a evaluation of the azimuthal position of the sun. This paper presents a way to estimate the sun position from the own satellite power system. This information is used for attitude determination, allowing the integration of two important subsystems of an artificial satellite.
