RTK Surveyor Base mode appears to never survey in/rtk2go connection drops

I have a pair of RTK surveyors that I want to use as a base/rover pair. They seem to work fine individually as rovers, I’m seeing a reported accuracy of 1.4m in SW maps. I assume thats not better because there are some mountains around and also I’m not that far from some buildings where I’m testing. However when I switch either of them to base mode the horizontal accuracy jumps up to around 8 m. And as far as I’ve seen it just stays there, even if I leave it for an hour or so to survey in. Additionally I want to broadcast RTCM from the base to the rover via rtk2go.com, but when I enter my information and hit connect there are zero bytes transferred, and the connection drops after a few seconds. I am guessing this may be because the base unit is not actually transmitting the RTCM, but I’m not sure.

Anyone know what the default survey-in settings for base mode on the rtk surveyors? Is it waiting a certain amount of time, or waiting until it achieves a desired accuracy?

I assume the RTCM is not broadcast until the survey in is complete, is that correct?

Any other reason my connection with rtk2go.com may get dropped? Will a base automatically connect as an NTRIP caster rather than an NTRIP client, or do I have to configure that differently in SW maps?

I tried looking at the product info available, but it seems it is mostly for the GPS board inside the surveyor, not the surveyor kit itself. I am assuming the base mode is configured to automatically broadcast RTCM. Or do I have to go into the u-center configurations to set that up? Seems like its supposed to be plug-and-play if you use a radio to transmit RTCM so I hoped it wouldn’t be too much more difficult to use two phones via bluetooth and wifi/cell-service.

If anyone could help me figure this out, that would be great.

Start here https://docs.sparkfun.com/SparkFun_RTK_ … -survey-in to ensure the device is transmitting (or attempting to)

You will need to configure an NTRIP caster https://docs.sparkfun.com/SparkFun_RTK_ … d-location

The main info you’re after though is likely this guide https://docs.sparkfun.com/SparkFun_RTK_ … d-location which will walk you through the process

Ah, it seems the default survey in stops at 5 m location accuracy, which is why mine never stops. (Although I don’t understand why its quite so bad.)

Looks like I need to use the wifi configuration, good to know. For some reason only one of my units will go into the wifi mode, but I guess one is enough, the other will have to be the rover.

I had seen that guide, but I guess I got lost in the details and wasn’t sure if it was for a surveyor kit or just for a bare ublox GPS board. I see the parts I need now, thanks. Seems like I should be able to get it working now the next chance I have to test it. Although annoyingly it seems my home wifi network password is too long to store it in the devices memory… (the configuration tool limits it to 30 characters!)

Thanks, I think I’ll be able to figure it out now.
