Reach RS+ as NTRIP base station

Reach RS / RS+ RTK / PPK configuration
1

Hi

Just wondering if anyone had experience with using a reach RS+ as a fixed NTRIP base station and using a second reach RS+ as rover.

I know there are limitations with cellular connectivity with reach RS+ but if I was to use the reach RS+ as a fixed base station it would have access to wifi at its location and the reach RS+ rover would connect via mobile phone internet.

What would be the realistic distances the rover can receive cm accuracy with a set up like this? Curious to see if anyone has experience with this type of setup. Thanks

Being on the internet you could theoretically go way further than you probably ever will, but recommendations would be a baseline of no more than 15-20km (10-15 miles). It would probably be a little less with an RS+ as it is an L1-only device and will only have access to around 30-40% of the data that a multi-frequency receiver can receive. As always this depends on the accuracy required for the situation.

Thanks Michael. Maximum I would be covering is 20km from the base station so accuracy may drop a bit. I do a variance of topography surveying and staking out of boundary lines/site set outs (which do require higher accuracy). Some of the time there is a known surveyed point nearby which I use to either directly connect rtk or else survey and post process if I don’t have line of sight. I was just looking to simplify set up so just carrying one unit most of the time.

You can easily hold 0.10ft (3cm) at the recommended baselines as that is how they were determined. You’re probably looking at an additional cm for every 10km over the recommendation. Just take a little bit longer observations.

That’s still very good for those distances. I will trial the setup over next week or so anyway and see how it goes. Thanks for the response

Hi @davidshandon,

As long as both devices are connected to Wi-Fi, the setup should work just fine.

We recommend sticking to the baselines up to 10 km with the single-band receivers, but, of course, the shorter the baseline, the better.

I’d also recommend recording the raw data logs as a backup for RTK so that you can process them later on if you lose the fixed solution.

As you know. For multi-freq receiver, 100km is significantly longer than the <60km requirement.

I think u may have meant to post here… still amazed this user with M2 and third party antenna achieved this… better check it against something known as may be a false fix.
