Mystery Ublox Hardware

 

Does anyone have any information on this board?  I bought a couple to take the LEA-4T off - it's a long story but I need the phase measurements and the UBLOX 4 series is fine - but it occurs to me that I may be taking it off this board just to put it on a board with similar features.  The problem is, I have no information on this board.

 

So, if you know anything about this board, I'd appreciate hearing what you think.

  • hello,
    I'm using the Lea-4T Ublox in UCenter and will not let me put it to 57600 baud UBX. In UBX only works to 9600 baud. Why?
     
    thanks
  • Hi, can anyone post some complete detailed information about using ublox receivers in RTK mode? pretty please? there isnt any well documented application i can find

    thank you very much

  • I got RTKLIB in PPP static mode to work with this board but didn't get a basestation/rover to work (help!).   You can use ucenter to enable and log RXM-RAW and RXM-SFRB packets.  Then convert to RINEX .obs format, wait till the next day and download ephemerides .sp3 info from http://geodesy.noaa.gov/UFCORS/ and then get all the RTKPOST options just right.

    http://wiki.openstreetmap.org/wiki/RTKLIB is an overview.

    In theory, one can use a pair of these boards + a radio link to get a few cm accuracy (relative to the basestation) in real-time.    The more readibly available NEO-6M is also supposed to work,

    you should install the u center to configure the receiver and you will test it from there. You may have data without fix. Check the antenna if you have active or passive one.

  • I just received one of these boards and am trying to make it work.  I connected it to a USB to serial converter but I'm not seeing any output.  What baud rate should I use?  Will it output something when power is applied or does it need to get a fix first?  Maybe I need to send it a command?   I assume that I swap tx/rx and rx/tx between the LEA-4T board and the usb serial board.  Anything else I can do to track down the issue?  Thanks.

  • i have the board now and it works pretty good. If anyone made the mod with the supercapacitor i d love to have at least a photo or a description of the mod or even the capacitor i should replace...

    Thank you

  • Anthony.

    Do you still have a supply of these boards or similar?  The whole works :-)

     Please contact me if you can help me out.

    Regards

    Andrew

  • i ordered that board as well from china but havent received it yet. i guess that with an ftdi cable and the drivers from the ublox site i ll be ok to connect them to u centre on windows or i missed somethind?

  • HI, I just ordered a board that looks exactly like this. Do you know what type of antenna connector it has? Thanks
