The HAST from Ball Aerospace is a Star Tracker that is capable of tracking multiple stars moving at 0-8 degrees/sec. This star tracker has a field of view of 8.0 x 8.0 degrees and an acquisition probability of greater than 99 %. It has an angular position estimation of 0.18 arcsec (1 σ) per star per frame and a sensitivity (MI) of 4.8 at a 100 Hz CCD frame rate. The star tracker has high accuracy providing 0.04 arcsec of pointing knowledge and has the capability to operate well beyond its 5-year lifetime. It requires a power supply of 22 to 36 VDC. The HAST is ideally suited for civil, commercial, and defense satellite systems.
