International Telemetering Conference Proceedings / October 22-25, 2001 / Riviera Hotel and Convention Center, Las Vegas, Nevada / The Range Instrumentation and Control System (RICS) is a PC-based client/server application designed to collect time-space position information (TSPI) from remote radar test sites and distribute it in real-time across a wide area network (WAN). The system architecture is composed of two main parts - the Data Interface Adapter (or DIA, which runs under VxWorks and is implemented using C/C++) and the RICS console PC (which runs under Windows 2000 and is implemented in Java). CORBA is used to provide communication between the RICS console and DIA. This paper describes the design of the system, focusing primarily on the DIA software.
