GPS

Bryan Sanders #1046 What program does everyone use to be able to see what satellites you are receiving?
km4ack All Messages By This Member #1047 xgps or cgps are the ones I use. You can start both from the command line. -- 73, de KM4ACK \| \|

David Thompson, AG7TX All Messages By This Member #1049 There is also gpsmon -n -- an interesting program as well. Since I generally eschew GUI programs, I tend to use cgps -s and gpsmon -n as my go-to programs for checking the behavior. The one thing I like about xgps is the graphical display of the sky view and satellites. Have fun!
Bryan Sanders #1053 Thank You David!? I am sure having fun with this pi 4.? Learning how to operate with command line has been interesting but fun also. toggle quoted message Show quoted text On Sat, Aug 8, 2020 at 12:19 AM David Thompson via <dbthompson=[email protected]> wrote: There is also gpsmon -n -- an interesting program as well.

David Thompson, AG7TX All Messages By This Member #1138 Bryan, You're welcome! Learn to love the command line. It is a very powerful tool and very unixy. I've had gpsmon -n running in a terminal window for over a week. I've been testing the GPS for my station computer and want a reliable source for time without having to rely on the Internet. 73 de AG7TX
Bryan Sanders #1139 David, ? ? I have an extension cable running from one of the USB 2.0 to my window. I also. Have a ferrite bead at each end.? This has been working flawlessly for a week now.? I also have been running gos on -n for a few days and I have been changing different things plugged into the USB ports. Only thing I found that effected the gps was a Bluetooth dongle for a wireless keyboard that I have.?

Mark, KE6BB All Messages By This Member #1147 开云体育 If you are using the little dongle GPS, then an extension cable will probably help.? The GPS antenna must have a clear view of the sky to have a reasonable signal strength.? In addition, the farther it can be placed from the noise of a USB port, the better the s/n will be.? USB 3.0 ports are the worst offenders.? Use an extension cable and pot that GPS antenna in a window where it can see the sky, or try one of these: https://smile.amazon.com/gp/product/B086ZK6R89/ It has a long cable, and a magnet on the bottom so it stays put on a magnetic (steel) surface.? I have used this model on my pc's for several years continuously 24/7 for timekeeping with no problems.? They are available on amazon from at least 2 suppliers. Mark,? KE6BB
David Thompson, AG7TX All Messages By This Member #1148 Thanks Bryan, I'm using a short cable because I want to know if I can operate the Pi4 in the field, which will require a short cable. For home use I don't care how long the cable has to be and will definitely use a longer cable for the home Pi4, if that's the way I end up going. Best...
David Thompson, AG7TX All Messages By This Member #1149 I understand Mark, My current objective is to determine whether I can operate this unit in the field with a short cable (of course). I'd prefer to mount the GPS receiver to the top of the Pi so keep everything close and tidy. My rig already has enough cables without adding to the cable mess. But for a home station with a Pi running as the station computer, right on. Best...

David Thompson, AG7TX All Messages By This Member #1153 Don, That’s an interesting unit. I might have to check one of those out.

Don Melcher All Messages By This Member #1158 I was in the marine electronics business at the arrival of consumer GPS. I don’t recall anything getting a fix from a cold start in a new location so fast.?
