On-Orbit Servicing missions are dependent on a robust relative navigation system allowing safe approach to theclient and the performance of the respective servicing mission. There are different physical sensor principlespossible; one of it is using an optical vision system which can be combined for both sensing and inspection.The VIBANASS project (VIsion-BAsed NAvigation Sensor System) comprises development, construction andverification of a versatile optical Rendezvous and Docking (RVD)-camera system including an illuminationsubsystem. The technical requirements for VIBANASS have mainly been derived from LEO and GEO missions. Aqualification model representative with regard to the flight hardware will be built for execution of a spacequalification programme. Functional performance verification will be supported using the new EPOS 2.0 (EuropeanProximity Operation Simulation) facility and dedicated image processing ground software which applies (adaptable)target specific distance estimation algorithms. The compressed or raw camera data serve as input for an RVD controlalgorithm.VIBANASS can be configured for mono and for stereo image acquisition, the latter being mostly used for shortdistances. The far-range camera images will be used for initial target identification starting from a few kilometresdistance (depending on the true size) and for subsequent tracking until the mid-range camera images becomesuperior in image quality.Light conditions during the final approach and the docking phase (if applicable) can be improved by activationand control of a laser-based illumination system, whose wavelength will be in accordance with the close-rangecamera, thus improving the image quality for distance determination.
