A secure data collection and distribution system has been created for Global Positioning System (GPS) research. Specifically, a program, RxData, has been created, using Borland C++, to produce a database from binary GPS data sent from the LAAS Ground Facility (LGF) data logger at the Ohio University airport. This data is sent through a one-way null modem cable which serves as a hardware firewall. In addition, several programs have been purchased, configured, and implemented to allow access to the binary data via a secure Internet connection. The secure connection has been established using 128-bit encryption between the FTP server, Serv-U FTP v5.0, and the FTP client, FTP Voyager v11.0, and all connections with the server are sent through a software firewall, Sygate Personal Firewall Pro v5.5, which protects the server and database from Internet related attacks.
