Click for latest NMEAgent Software Update
Updated (October 14, 2014) and tested on Windows 7 (Win 8 status unknown)
Aug 10, 2014: View up to 50 GPS, WAAS and Glonass SVs.
Sep 14, 2014: Now GPS and Glonass simultaneously from Holux M-215+ and Canmore GT-321R. Others as I get one or data from one.
Oct 18, 2014: Updated program to better handle a problem one of my GPS units created where it put a PRN in the wrong place for a while.


Previous updates

If you have having trouble with a feature, please record a file (built into the program) and send it to me at the email shown on this page so I can run the file and see where the problem is. Otherwise, I will not be able to find or fix it. Thanks.

Note: The preceding two links download .ZIP files.
If you do not have quality ZIP/UnZIP capabilities, please download an excellent FREE ZIP handler (and SO much more) named jZip from www.jZip.com.

(No, I don't get any money out of this recommendation.  It is just a very good program I use a lot.)


Here is a graph showing the tracks of GPS and Glonass satellites over a couple of days.
GPS plus Glonass Orbit Tracks
In the preceding image, GPS satellites are tracked in blue and Glonass sats are tracked in red.  GPS (USA) PRNs are 32 and less.  Glonass (Russia) PRNs start at 64 and go up.  The center of the plot is in Vallejo, CA, near the cities of San Francisco and Napa near 38° 08'N / 122° 12'W.  I can almost see "over the top" from here but not quite.

You can see a couple of interesting things from this plot from the free NMEAgent program.  GPS sats have a lower inclination than do Glonass sats.  That means that Glonass sats go closer to the north and south poles than do GPS sats.  GPS sats do not hit the same track every time.  It is general "knowledge" that GPS sats are in the same place in the sky every day, twice a day.  While that is somewhat true, they precess across the sky and the orbit time is about 4 minutes short of making it to the same place every day.  But Glonass sats, while about 45 minutes short of a repeating orbit, hit orbits which precess across the sky in about an 8 day repeating cycle.  You can see the rather regular pattern of the red traces around the pole.  These tracks were recorded across a couple of days by NMEAgent software.  The numbers on the chart are PRN numbers.  Since Glonass sats don't have well associated PRN numbers, these are the ones assigned as of the date this track was recorded - Sep. 2, 2014.

These days, there are many GNSS receivers that are without a display.  This makes them cheaper.  They can be plugged into various devices and those devices become the display for the GNSS receivers.  Google Earth will accept NMEA input from a GNSS receiver connected to a compatible device speaking NMEA data.  That is how this display was developed.  The track was partially developed using a GT-321R and partially from a Holux M-215+.  The Holux sees only one WAAS sat but will not track it.  The GT-321R will track either GPS+WAAS or Glonass.  So a complete picture can be developed but it needs input from both.  I am hoping to find a receiver that will display GPS+WAAS+Glonass.  There is supposed to be a uBlox based unit which will do this as of their release 8.  As of now, these units are not widely available.  I will try to get one when they do become more generally available.

I took a very short piece of music and looped it many times. It puts my brain into a meditative state. It runs over 60 minutes and is, to me, very pleasant. Let me know how it hits you...

Here are some pictures of the Pleasanton, California Model Train Layout.  They have put a LOT of work into this and it looks really good.  Of course, it take a good photographer, too, right.  I hope you like the work of the layout builders and the photographer (me).

Note: About 70 more pictures were added in early October 2014.
Enjoy this in-depth look at a very nice, large model train layout.
