Investigation of geo-tagging technology and capabilites for Earth images obtained on human space vehicle using freely movable cameras

An angular system for geo-tagging of photographic images taken by cosmonauts using a freely movable camera is described. The development testing results for such authors-proposed system construction options developed based on a small-size sensor of Xsens Technologies B.V. (the Netherlands), sensor of Research and Production Company Optolink (Moscow), ultrasonic sensors of RUCAP (Moscow) are presented. The proposed system options are investigated within space experiment Vizir. A description of the developed system composition, key performance, algorithm for computing photographic image center coordinates are provided. A new mode of computer-aided photographic equipment pointing to specified earth surface objects via voice commands is described. Calculation examples are given, and further research areas are formulated.
