A compact horizon sensor has been developed for use on TECHSAT-1 and other small satellites. The stringent requirements for low weight and power have been met by designing a static sensor with a new type of thermal detector array. The sensor uses four identical telescopes mounted at an optimal angle for the satellite altitude, and a microprocessor to convert the data from the detectors into an accurate measure of the angle to the nadir.
