Have you done a physical inspection up on the tower? And has another tenant fired up anything new on the tower that could be interfering with GPS signals, either by physically blocking the view of the satellites, or RF interference? LightSquared testing some equipment on your tower?
Are there any GPS interference tests being conducted by the government in your area? http://www.navcen.uscg.gov/pdf/gps/gpsnotices/GPS_Interference.pdf From: Jeremy Sent: Monday, November 02, 2015 8:42 AM To: [email protected] Subject: Re: [AFMUG] All units on a tower lost GPS sync I've seen GPS antennas die before, seen water in a type-N conenctor, and have seen the sync source die (daughter board on a CMM3, or whatever on CMM4. There are a few points of failure that could cause that. On Mon, Nov 2, 2015 at 7:21 AM, Josh Luthman <[email protected]> wrote: What radios? What's giving them sync?

Have 3 sectors and 2 backhauls which keep losing GPS sync. Can reboot the units or turn gps off and on by selecting a different source and then changing it back GPS. It then works for a short time before it stops again. On phone with Cambium but there seems to be a language barrier at the moment. :-) These have been rock solid for months until about 8am EST this morning. Any ideas?
