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: <http://www.hearsat.org/nims.txt> <http://sgdwww.arlut.utexas.edu/cir/transit.html> <http://www.haarp.alaska.edu/haarp/its.html> And, for some recent observational results, see, for example, <http://maestro.haarp.alaska.edu/cgi-bin/its10/plot-tec.cgi?location=gakona> -- Richard Langley Professor of Geodesy and Precision Navigation On Fri, 26 Dec 2003, Brooke Clarke wrote:Hi: 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. http://www.pacificsites.com/~brooke/90BA.shtml Happy Holidays, Brooke Clarke, N6GCE http://www.PRC68.com=============================================================================== Richard B.
