Abstract : The problem addressed by this thesis project is to connect two global networks, the Amateur satellite service with the World Wide Web. The ground station computer formats its data in the PACSAT File Header (PFH) format and the World Wide Web requires Hypertext Markup Language (HTML) format. The approach taken to solve this problem was to create two conversion programs. The first program converts the PFH format to HTML for directory listings of messages and the second program decodes the telemetry downloaded from the satellites to a text file, both of which are made available to the World Wide Web server. The result is a gateway between the Amateur Satellite Service and the World Wide Web so that users can access the message database and telemetry of each satellite using a World Wide Web browser program. The gateway has averaged 350 accesses per day during five months of operation from 3057 hosts in 41 countries. Several e-mail messages have also been received commenting on the gateway's uniqueness, utility, and originality. (AN)
