Celestial navigation, which is the automatic tracking of stars to determine position, is employed widely in missile guidance, satellite attitude determination, aircrafts and spacecrafts. Celestial navigation is performed by Star Tracking Systems. A Star Tracking System uses stellar references obtained by various narrow-field-of-view "Canopus trackers" cameras to update inertial references.
Marlow Industries provides thermoelectric coolers, qualified for space, to cool the detectors in these cameras. Cooling the detectors increases their sensitivity. Marlow also offers mounting of the TEC into packages for our customers.
