Hopefully timing receivers using elevated gps antennas with band pass filtering (ie. the 58532A or equivalent..) and a good sky view and strong signal levels will be more resistant to out of band interference than a typical consumer grade portable GPS with a built in antenna at ground level with a sub optimal sky view. In my oppinion timing applications are likely to be one of the few GPS applications where a reasonable mitigation path exists (ie. band pass filters could be added between the receiver and the antenna, antennas with modified radiation patterns could be used etc..)
Providing a solution for the GPS receiver built into my black berry will be siginficantly more difficult in my oppinion. ----- Original Message ---- From: David J Taylor <[email protected]> To: Discussion of precise time and frequency measurement <[email protected]> Sent: Wed, February 2, 2011 12:17:27 AM Subject: Re: [time-nuts] From GPS World - Lightsquared has been given the goahead >http://www.gpsworld.com/gnss-system/news/data-shows-disastrous-gps-jamming-fcc-approved-broadcaster-11029?utm_source=GPS&utm_medium=email&utm_campaign=Navigate_01_31_2011&utm_content=data-shows-disastrous-gps-jamming-fcc-approved-broadcaster-11029 >9 Sounds like the "planning" folk here in the UK who allowed high-power pager transmitters right next to a satellite space frequency (135-137MHz), rendering part of that band useless if you were near a pager transmitter. Except that stopping GPS working will affect rather more folk than interfering with weather satellite reception. 73, David -- SatSignal software - quality software written to your requirements Web: http://www.satsignal.eu Email: [email protected] _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
