The ESA Rosetta spacecraft has been tracking its target, the Jupiter-familycomet 67P/Churyumov-Gerasimenko, in close vicinity for over two years. It hoststhe OSIRIS instruments: the Optical, Spectroscopic, and Infrared Remote ImagingSystem composed of two cameras, see e.g. Keller et al. (2007). In some imagingsequences dedicated to observe dust particles in the comet's coma, the twocameras took images at the same time. The aim of this work is to use thesesimultaneous double camera observations to calculate the dust particles'distance to the spacecraft. As the two cameras are mounted on the spacecraftwith an offset of 70 cm, the distance of particles observed by both cameras canbe determined by a shift of the particles' apparent trails on the images. Thispaper presents first results of the ongoing work, introducing the distancedetermination method for the OSIRIS instrument and the analysis of an exampleparticle. We note that this method works for particles in the range of about500 m - 6000 m from the spacecraft.
