Novel Advancements in Internet Based Real-Time Data Technologies

With increasing advancements in Internet technologies the generation of on-site technical experts will quickly fade. With the capability to distribute real-time data over the Internet, collaborative efforts between scientists and field experts can occur instantly between remote locations without the need for costly travel expenses. Real-time data distribution has historically been through dedicated hardware circuits with pre-defined data visualization tools. EZStream proposes to provide a common ground where multiple telemetry processing applications (TReK, SQL, OPC, NI, etc?) can interface and send data over a Local Area Network or the public Internet, using flexible easy to use display development tools. Phase I will utilize Java software products previously developed to interface with TReK to provide live data displays for the NASA Learning Technologies Project, Live From Space Stationa. Research will be performed on interfacing EZStream with existing commercial Nematron products. These systems, which successfully utilize Internet standards (e.g., TCP/IP, Java), will serve as baseline references for applying higher-level standards: data acquisition and distribution techniques. In Phase II the most proven capabilities will be incorporated into a prototype EZStream application and interfaced with TReK and Nematron products to provide telescience tools to both NASA and the commercial sector.
