    Good Morning All.

    Could anyone please help me with the details of connecting a Topcon VR GPS Rover to work with a Trimble R750 GNSS Base Station.

    Thanks.

    Dee

    Why are you posting in the Mapping and GIS community for this? I would try posting here: https://community.trimble.com/communities/community-homepage/digestviewer?communitykey=aed48040-ff0f-40aa-9750-a83b700ddf97&tab=digestviewer. I am guessing that you just need to match the over the air radio baud rate and flavor between the Trimble Base and Topcon rover.

    Hi dela,

    to get a hiper vr rover to work with an r series base

    1. setup and have it stream rtcm 3.2 msm corrections
    2. in Trimble access create a survey style base r750 for example
    3. go to base options, survey type is rtk, broadcast format rtcm rtk 3.2 msm
    4. radio set whatever you have (example internal then connect set to the radio channel and not your settings… default is trimtalk 450s @ 4800 )
    5. start base and it should transmit
    6. for Topcon rover depending on software (magnet field is the easiest to config
    7. go to settings and setup to receive rtcm 3.x, configure the rover radio to match the base radio channel and settings..
    8. away you go should work… if msm doesn't work you can go back to rtcm rtk 3.0 which will only transmit the gps and glonass

    hope this answers your question

    Hi,

    I meet a problem between a R750 and Hyper VR Mobile, the both devices had the full constelation option (gps+glo+bds+gali).

    I use RTCM 3.3 MSM to transmit to the mobile but when i look on the mobile i can see on  the mobile 25 satelites saw and aprox 13 used...

    If someone have ever meet this problem..

    Regards, Louis (Sorry for my english :p French User)
