Data Application Plan

• Real-time data collection and distribution by existing internet linked system

• No cost Operations by volunteer ground stations and other schools and universities

• Transparent data relay, collection, distribution. Independent of system operation

• Only sender and receiver of data need to collaborate

• WEB Browser access to all data

SCIENCE (USNA-0203)Potential Experimental Users

SCIENCE is a low cost educational transponder supporting not only ODTML, MIDN and other experiments but also University and School Experiments.

Background

The University channels can potentially draw from over 30,000 experimenters for easy assessment of loading and scaling issues.

Not only the sensors and users exist, but the global Internet collection and distribution system also exists from PCSAT1 & 2.
