The Acra KAM-500 Data Acquisition Unit (DAU) is an airborne acquisition and transmission system that consists of a chassis, a backplane controller and user-selected modules. This highly configurable system enables fully customized systems to be built using commercial off-the-shelf (COTS) product.
The KAM-500’s physical characteristics, such as compact, low weight and high performance design, are coupled with architectural decisions to ensure low latency, deterministic and coherent data flows. The finite state machine design ensures that the hardware acts in a completely deterministic manner so the output data can always be related to the source. Coherency is maintained as all parameters are sampled simultaneously, and independently of transmission, across the complete system in every card in every chassis making it unnecessary to realign or interpolate samples during analysis.
