ANNA I MEMORY,
Abstract
The memory unit in the ANNA satellite is employed to initiate flash sequences in an optical beacon system at predetermined real times. Requested times for optical sequencing are converted to binary numbers which are injected into the memory. Each binary number is a function of the real time of injection and the real time start of each requested sequence. The memory operates on these word oriented numbers and commands the optical logic at the appropriate times. The memory unit occupies 1350 cubic inches (see figures 1, 2 and 3), it weighs 21 pounds, and consumes 1.3 watts of power. The unit is designed to operate over a voltage range of plus or minus 15% and a temperature range of +135 deg. F to -10 deg. F.
