I thought this might be of some use to the members of the list who do detailed analyses of satellite orbital behavior. Since I'm currently Web-impaired, I haven't been able to see what the actual contents of the site are. -------------------------------------------------------------------------- The NOAA Space Environment Center, formerly Space Environment Lab, is announcing today, November 13, 1995, a new service available to the navigation community via the World Wide Web. To allow quick access to space environment data that relate to the function of GPS, Loran-C, and Omega, the Navigation Systems Page is now available over the web. There are sections specific to GPS, Loran-C, and Omega, that include both real-time data as well as short explanations of how the data may be used. The address of the Navigation Systems Page is http://www.sel.noaa.gov/nav/nav.html. User comments are desired as this service will evolve to meet the needs of the navigation community. Send your comments either via the e-mail address at the bottom of the page, or directly to Joe Kunches (jkunches@sel.noaa.gov).
