GPS "Compound Eye" Attitude Sensor

A proposed Global Positioning System (GPS) sensor would give information on approximate attitude as well as on position. Unlike other GPS-based attitude sensors, this attitude sensor would not depend on carrier-phase measurements and thus would not be subject to the difficulties and limitations involved in determining attitude from such measurements. Instead, this attitude sensor would be based on a concept that is related to that of an insect's compound eye and that has been implemented in optical attitude sensors of the star-tracker type.
