Reasons for Satellite Mission Miniaturisation and its Consequences

Abstract

There are at least two reasons for satellite missions miniaturisation: - Transition form Earth exploration to Earth watch with concentration on specific phenomena to be observed with optimised sensor systems, - Development of advanced technologies in many fields of engineering sciences. The miniaturisation is supported by high-end off-the-shelf technologies and instruments for quick and low-cost realisation as well as by the extensive use of advanced technologies leading to increased mission performance but also to higher costs. The paper gives examples for mission design, space segment design, and instrument design, respectively. All the experiences and examples shown in this paper are mainly based on activities of the DLR - Institute of Space Sensor Technology.
