I have an issue that I am trying to figure out regarding the information in the subject line.
I am testing Carlson SurvCE Version 3.03 with a Topcon GR3 as a base, 1 GR3 and 1 GR5 as rovers. With MAGNET I think there is an option to connect to an existing base once the base and first rover are set up for the 2nd rover.
I'm quite sure I am screwing up a step somewhere in SurvCE.
Here are my steps in outline form:
1: Setup and configure base
2: Setup and configure 1st rover from same data collector that base was setup on.
3: Make control check. All is good with tie in
4: Setup and configure 2nd rover on another data collector. Here lies the issue.
4A: I see no option to add that 2nd rover to an existing base so what I try and do is configure the base from the 2nd rover's data collector and then proceed to setup the 2nd rover.
4B: The 2nd rover checks in fine but the 1st rover is invalidated and does not check.
I realize some details are missing in the steps above but I can get one base and 1 rover to work fine so I left out some detailed settings. If you need a particular setting I can forward on.
From a logical perspective, this makes complete sense. You cannot "restart and reconfigure the base" but it's the only way I can tell Carlson that the 2nd rover is using this base.
Anyone run into this?
Maybe a broadcast ID issue? In other words, does Carlson require one data collector to configure the base using one broadcast ID and the other data collector use another? Just a thought
Again I feel it's my step approach that's wrong.
Thanks
Just to clarify, after you initiate the second rover, is the first rover staying "fixed" but the coordinates are now wrong? Or is the first rover going to "Autonomous", and therefore the coordinates are off?
both stay fixed. 1st rover's coordinates and elevations are off and 2nd rover typically checks in good.
Let me first say I do NOT use Carlson field software, but I use those receivers often. You should NOT need to setup a base at all on the second controller. We run lot's of projects with multiple rovers, just one base. We even span multiple vendors equipment on same project. As long as you have the correct parameters in the second controller for GPS radio protocols, freq's, rtk data type, and projections. You can just connect to rover to your controller, and it should find the base that is on same radio freq.
I assume you've done this. But sounds like you need to check that the radio settings and protocols are exactly the same in both controllers.
Sounds like you performing steps to config the base twice, when you should only do this once. Either way, even you setup the base twice it should still be seen by both Rover's if radio parameters are matching.

First off, I agree with post below, that you should not have to set the base with the 2nd DC, you should be able to go straight to the rover set-up on the second DC.
But, I'm still wondering why this isn't working for you. Are you setting up on a known control point, and keying the base coordinates into the both DCs? Are you sure you have the exact same coordinate system selected? Are you using localization on the project? A lot can go wrong with localization.
That's what is strange...both settings are the same but will verify again for sure.
Again I do realize that I shouldn't have to setup the base twice but it seems to be the only way to get the 2nd rover to "see" the base.
MAGNET (from what I remember) has the option to pick the existing base when setting up the 2nd rover.
Crew's coming back in a few and will continue to test. I will check the settings again and retry.
Let ya'll know.
Thanks for the input.
I too agree.
Yes I am using a known point for the base. Carlson seems to create what appears to be 1 point localization when using "known position". I am prompted to save a .loc file (localization). In fact, after setting up the system you can move over to the localization tab and the known point is in a table.
I can also save my current base config as a .ref file (reference). This allows you to select that file instead of reconfiguring when you setup on the base some other day for instance. I usually do not save a file at this point.
What baffles me is that I can setup a 1 base/ 1 rover config this way and all is well until I try and add the 2nd rover. Likely a check box somewhere I am not seeing in the rover setup.
I'd look at Trans/No Trans.
I too thought of that.
Base translation is off from what I remember but will go through the setting again.
Thanks
I know what you are doing wrong and its just the way you are setting up the base. Already been through this myself. Call me at 501-250-4229 and i will walk you through it.
