Abstract
We describe a sophisticated for the collection of numerous streams of image and aircraft state data from an airborne platform. The system collects and stores 7 different sources of analog video data; 3 separate sources of digital video data at aggregate rates of up 32 Megabytes per second, to a removable tape device of 100 Gigabytes or 50 minutes' capacity; low-bandwidth aircraft state information from inertial sources; and other ancillary data. Data from all sources are timestamped with a common time source for synchronization. The task of accurately timestamping multiple disparate data sources is a challenging one, and it is discussed in some detail. Although the technology that can be applied to this kind of effort advances and changes rapidly, certain design paradigms remain valid independent of the specific implementation hardware. General principles of design and operation, as well as system specifics, are described; it is hoped that this record will be a useful reference for future efforts of this kind.
