| Abstract |
The University of Wisconsin's Space Astronomy Laboratory has designed
and built a Star Tracker suitable for use on sounding rockets and class
D satellites. This device brings together autonomous attitude
determination ("Lost in Space" mode), multi-star tracking, and a novel
form of Progressive Image Transmission, which allows the device to be
used as an ultra-low bandwidth imager.
The Star Tracker 5000 reached operational status in a suborbital
sounding rocket flight in August 2007. The ST5000 determined the
rocket's inertial (FK5) attitude using its autonomous attitude
determination capability, and then provided continuous sub-arcsecond
tracking for the full 360-second on-target portion of the flight. The
ST5000 RMS tracking error was 0.54 arc-seconds in Yaw and Pitch, and 17
arc-seconds in Roll. The vehicle RMS jitter was 0.5 arc-seconds in Yaw
and Pitch, and 10 arc-seconds in Roll.
The ST5000 was funded by NASA grant NAG5-8588. |
