Abstract:
transmission of data from sub-orbital vehicles is accomplished primarily through the use of RF telemetry methods. One suggested approach to assure data transmission during a RF blackout employs a supplementary flashing light transmitting system. In this system the flashing light encoder has the assignment of transforming data information imposed on a group of FM sub-carrier channels into a form compatable with a flashing light transmitter. The encoder samples the frequency in X-channels and converts each frequency into a time interval between two flashes. The coincidence of the start of one sample with the termination of the previous sample provides for maximum efficiency in the utilization of time and power. Author
