Operational Terminals and Workstation Applications

We have mentioned earlier that the Naval Ocean Systems Center (now defunct) and the Naval Research Laboratory teamed in the development of a terminal concept for evaluation of system impairments introduced by ionospheric effects [Rothmuller, 1978], The SOLRAD satellite provided space weather data, and the terminal contained an imbedded set of simplified models that could be updated by the satellite data in real time. This was probably the first attempt to exploit space weather data in an operational environment. Tests were successful but the program was eventually cancelled to fund other priorities.

A regional nowcasting and forecasting system for UHF and L-Band scintillation has been developed by the USAF and is currently being tested. This system, called SCINDA, utilizes data from terrestrial receivers to generate tailored products, and might be regarded as an intelligent scintillation detection and tracking system [Caton et al., 2002], The USAF has also developed an Operational Space Environment Network Display (OpSEND) that provides easy-to-visualize displays of space weather effects on designated systems. Nowcast and forecast options are available [Bishop et al, 2002]. (The reader should refer to Section 4.5.3 and 5.6.)
