Star sensors developed in the last years can be enhanced in terms of mass reduction, lower power consumption, and operational flexibility by taking advantage of improvements in the detector technology and the other analog/digital electronics components. The Jena-Optronik GmbH (DJO) is developing an Intelligent Modular Star and Target Tracker. Emphasis will be placed to increase the sensor adaptability to meet specific mission requirements. There are some new features in the sensor design. The Intelligent Modular Star and Target Tracker shall generate positional information regarding a number of celestial targets or shall act as a navigation camera. The targets will be either stars or extended objects like comets and planetary objects, or both simultaneously. The technical approach for the Intelligent Modular Star and Target Tracker will be presentcd in detail in the scope of this paper. Because of the modular concept the sensor can be adapted to different mission requirements. One of the potential target missions is Rosetta, where star tracker as weIl as navigation cameras arc required.
