The Satellite Attitude Sensor (SAS) utilizes infrared bolometer arrays to perform the role of a staring horizon sensor with good accuracy and a wide field of view that avoids mechanical scanning. An innovative concept has resulted in a simple and inexpensive design suitable for the requirements of both low and high altitude orbits. Although SAS was designed especially for Earth-observing micro-satellites, it is applicable to satellites with geosynchronous or highly elliptical orbits and the update rate is sufficient for use with a spinning satellite or a rocket. The ability of the sensor to operate in both spinning and 3-axis stabilized modes will allow it to fulfill the needs of a large variety of scientific and remote sensing applications. Laboratory tests are in process to verify the design.
