Earth Image Acquisition
Digital aerial camera control systems for photogrammetric solutions require acquisition and distribution of large amounts of data or the exploitation of the area. One or more specific cameras that are able to produce extreme wide-ground coverage are installed in the fuselage of a plane for aerial photography. The photos are taken from a height of up to 5000 meters and are used for mapping or track surveying, for example. Using special filters in front of the camera, "invisible" factors can be documented - like the chlorophyll content of a corn field made visible in order to determine the amount of fertilizer needed.
What makes using a 3U CompactPCI Serial system in this application attractive is the fact that it is mission-critical. On the one hand, the camera data has to be checked when still in the air because the flights can only take place in good weather conditions. For this, the system has to function reliably at all times. On the other hand, the electronics are subject to harsh environmental conditions regarding temperature, humidity, shock and vibration.
