UH/Aloha Participation in the ATS-1 Computer Communications Experiment

Abstract

This U/A report describes the status of UH/ALOHA participation in the ATS-1 Computer Communications Experiment through January, 1974. This experment was initiated in January, 1972, by the Spacecraft Data Systems Branch of the NASA Ames Research Center, to demonstrate the feasibility of utilizing satellite communication links to rpovide computer-computer and terminal-computer communications between remotely located sites. In order that the experiment be conducted under realistic conditions, computing facilities at the University of Hawaii and the University of Alaska were connected ot the Advanced Research Projects Agency computer network, via an ATS-1 VHF link, through the Terminal Interface Message Processor located at the Ames Research Center. The ATS-1 VHF transponder was utilized as a broadcast repeater for the three nodes mentioned above, with the satellite network operating in the ALOHA random-access burst mode.
