    Hi Richard:

    Thanks for the links.  Now I know that my Transit navigation receiver will no work, although it does detect flyovers and tries to lock to each one.

    Happy Holidays,

    Transit, or the U.S. Navy Navigation Satellite System (NNSS) was
    decommissioned in 1996. However, the system was converted over to the Navy
    Ionospheric Monitoring System (NIMS). The satellites continue to transmit
    their 150 and 400 MHz signals albeit with a different "proprietary" signal
    format. For further information, see:

    I recently got a Transit Satellite receiver, a Magnavox MX 4102, mostly
    out of a curiousity.
    I know the Transis system was shut down a number of years ago, but was
    wondering if there are still any satellites that are operational?
    On my web page for the MX 4102 there is a link to the Johns Hopkins
    Applied Physics Lab web site for Transit with a number of interesting
    papers about transit and a short paper by Dava Sobel.
