Descent imaging by ROLIS is limited by onboard memory. So plan is that ROLIS will take few pictures after release from the orbiter, those will be immediately transfered to the orbiter and
then erased. FOV size is easy to find, because if you know distance, you now FOV size on comet. From distance 1000 meters FOV diameter is 1000 meters and resolution is ~1 meter. Before touchdown ROLIS will take up to 8 images from maximum distance 25-50 meters (FOV 25-50 meters). Only few last images will be better in terms of resolution than best possible images from OSIRIS camera. CIVA has 60° FOV. Its cameras has FOV tilted down by 15° (25° for stereo camera) from the Philae's baseplate ("horizontal" plane). So it can see ~270 meters high peaks in distance 1000 meters (this of course depends on actual tilt of the lander). Source: Space Science Reviews 128. -------------------- |
