  1. Flying today with the express intention of checking out GPS.

     

    I will try with my Taranis and my Tandem X20 to see if there are any differences.

    I think most of my logs that do not have that GPS line are from the Tandem X20 and ETHOS.

     

     

  2. Been doing some tests myself!!

    Managed to connect to many satellites.

    Did a quick test with GPS set to DMS

    I now have a GPS column.

    And the trace puts it exactly over my house!!

     

    All tests conducted using a Taranis X9D running Edge TX 2.9.2

    I shall investigate further.

  3. I had a thought at work today!!!

    Maybe it has something to do with the way the GPS is configured in the "radio setup screen" this on my Taranis X9D running the latest EdgeTX. Can not remember the last time I played with the X9D. Sure seems antiquated. No touch screen etc etc.

    Been sat now for 20 minutes waiting for the sensor to pick up even one solitary satellite. Currently I think it may have to do with the Coordinate format DMS/NMEA

    Storm Henk is battering my location at the moment and cloud cover is 10/10. Not ideal for our budget level GPS to work under.

    I will try again tomorrow.

    I have an FrSky GPS sensor V2 which I used a fair amount in the mid 2010s. I can't remember when it, or what, went wrong, but following an OpenTX update it would no longer link to Google Earth and the format of the data recorded in the SD log file was garbled. Therefore I haven't used it recently.

     

    However, having read the thread above I decided to have a play with it this evening. I connected it to a receiver, waited until the red led changed from quick flashing to slow flashing - indicating a satisfactory GPS position was fixed - and recorded a 4 minute log.

     

    I copied the log file onto my computer and accessed it with OpenTx Companion. Much to my surprise it opened Google Earth, read the data and opened a display of the recorded position.

     

    That's when things didn't go so well! I was indicated to be somewhere in/on the North Sea - not so good. However, the latitude was correct, but the longitude was not. The problem is that I live around 0.5 deg. west of the Greenwich meridian and Google Earth takes 0.5 as being East.

     

    The answer in the short term, in order to display the correct position, is to change the longitude data to read -0.5 deg. then all is well. I did this using a spreadsheet, but it's not a quick and simple task. However it does at least show that it works, more or less. The problem is that if you fly across the meridian then this won't work.

     

    There may be a simple configuration, either in OpenTX or in Google Earth, which would fix this, but I don't know.

    Interesting.

    I just did something similar. Loaded an "old" log file and it went straight to Google Earth.

    Tried to do the same with a "newer" log file and there appears to be a number of changes in the way the GPS is read. So I get the following error.

    Note on the left hand side we now have two fields called Latitude and Longitude.

     

    Using the old file.

    Clearly marked GPS. This one imports into Google Earth no problem.

     

    I shall investigate a bit more.

    Is DataExplorer any use? https://www.nongnu.org/dataexplorer/

    It's a free app, and I know it works well with a number of brands of telemetry/logged data. It seems to have an Open-Tx option, but not sure if that applies to the latest FrSky telemetry data. Perhaps worth a look?

    As well as displaying the data graphically I can also use it to download GPS data into Google Earth to show a flight. There are various versions for PC or smartphone.

    Nope, it was way easier than that. No additional software involved, other than Companion and Google earth.

    At least that is how I remember it!

  6. I use the FrSky version extensively. Speed and position seem to be fairly accurate.

    Many years ago I manged to import the data and show a flight plan on Google earth. Can not for the life of me remember how I did it. If any one knows please tell me.
     




    There is also this as an alternative. Bit on the pricy side though.

    I like them. I also have telemetry set up to call out speed, height etc etc on a button on my X20

  7. A couple of mine also need the RTC battery changing. 

     

    Probably shall not bother now as ETHOS looks like it is dead on the TX12S.

     

    The second is a BETA machine and rarely sees the light of day.

     

    The other on Edge with touch screen mod does not need doing.
