Payloads onboard of orbiting spacecrafts around planetary bodies of our solar system are very strongly limited in mass because of the challenging Dv requirements to transfer the spacecraft and its scientific payload from Earth to the selected body and perform the orbit insertion. Also the overall cost envelope of the mission play a major role in the limitation of possible payload mass. On the other hand a range of different instruments (cameras, UV- and IR-spectrometer, Gamma-ray, x-ray and neutron spectrometer, laser altimeter, etc…) are required to perform a successful exploration of the planetary body by means of remote sensing. A viable solution is a strong integration of the envisaged instruments into a suite of instruments rather than a collection of single more or less independent instruments. The suite has to share available resources as much as possible and uses a central data handling system and an optimised payload power supply. Use of newest technologies for the detectors helps to reduce or at least relax cooling requirements of the instrument suite. Combination of instrument apertures and optics lead to a further reduction in mass and help to simplify the thermal design of the spacecraft. In the frame of the BepiColombo mission the instruments onboard of the Planetary Orbiter (MPO) undergo such an integration and optimisation process. During the talk the proposed instruments suit architecture and the resulting reductions in resource requirements are presented and compared with a conventional instrumentation approach.
