This paper examines the use of a multi-chip color camera as hardware candidate for color star tracker technology; i.e. a Prism-CST. The Prism-CST hardware presents many advantages over contemporary color image sensors, including pixel high resolution and distinct spectral filter bandwidths. To take advantage of these benefits, previous centroid estimation techniques are extended to retrieve precision position and color information. Additionally, we propose a effective methodology for calibrating the Prism-CST hardware prototype in a laboratory environment. Finally, a combination of laboratory and field testing examines the measurement performance possible with the Prism-CST hardware.
