The Rocket Lab ST-16HV is a star tracker designed for space applications.

It is an attitude determination sensor based on the heritage, high-performance ST-16RT2 star tracker, but with component selection and manufacturing processes optimized for high-volume applications.

The ST-16HV uses an off-the-shelf optical solution in place of a bespoke lens, enabling mass production and cost savings. Using the same concept of operations and electronics design as the ST-16RT2, the ST-16HV is drop-in compatible with the ST-16RT2 making bus customization trivial on a mission-by-mission basis.
