Abstract: Optronic tracking and guiding instruments are maintained in a readiness state by simulating various conditions including mechanical loads and, possibly, temperature variations for obtaining a set of corrective data which is then used for compensating possible errors during a real live mission. The compensation involves particularly focusing and exposure time control.

Abstract: The system includes a plurality of mobile optical-electronic data acquisition stations for individual training on particular mobile targets. These stations are linked through an information exchange and distribution system with a common center cooperating with these stations in a real time configuration for purposes of generating data representing the trajectory of one or more targets on which the optical-electronic acquisition stations are trained.

Abstract: A data acquisition system includes groups of transducers, a separate commutator for each group cyclically interrogates the transducers of the group. The resulting signal trains are separately decommutated and the data from each transducer group are stored in separate buffer systems. Each buffer system has a pair of buffers which alternate between reading and writing and a mask control selectively causes updating of the buffer content or copying from one into the other. A third buffer in each system is continuously updated. A formatting processor calls on all buffer pairs to assemble a PCM signal train in which the data from each transducer occur at least once in a cyclically repeated main frame. Buffer locations more frequently updated are called on more than once in the main frame. This processor is programmed to assemble the buffer addresses by counting up from starting addresses for a ROM that holds each buffer address once.
