DOI: 10.1016/j.asr.2018.10.030
Abstract: Abstract We analyse the inter-boresight angles (IBA) measured by the star trackers on board the GOCE satellite and find that they exhibit small offsets of 7–9″ with respect to the ones calculated from the rotation… read more here.

DOI: 10.1109/taes.2020.2971289
Abstract: Star trackers are autonomous, high-accuracy electronic systems used to determine the attitude of a spacecraft. In recent years, commercial-off-the-shelf (COTS)-based star trackers are growing in importance for low-cost and short-duration missions, but their fault tolerance… read more here.

DOI: 10.1109/tim.2021.3135343
Abstract: A star tracker operating inside the atmosphere requires stellar atmospheric refraction (SAR) correction with rapidness, autonomy, and accuracy to promote its attitude determination. To meet this demand, a joint estimation of the SAR and star… read more here.
