RS2 - The 33/66km RTK session with ntrip/simcard

RS2 stuff i have collected the last few weeks. Two things i was eager to try, the long range RTK and second the built in simcard solution. And, yes. It worked amazingly well.

I didn`t have any VRS available this time so i had to rely on monuments. Luckily we have few of those

As some of you know i have made my own mountpoint to access local AP at my home. It has been surveyed and controlled a gazillions times using a nearby highly accurate monument and againts other know points. It was natural to use mine as base for this session. But the pictures and vidoes you will see later are taken from a monument located nearby, just because the view is so much better.


Base coordinates is verified to be within 7mm horizontal accuracy, and the same goes for the two points at the rover.

Base is set with all RTCM messages enabled at 1hz, RTK mode was set to 5hz and i used www.rtk2go.com for ntrip. Base is connected to internet via my home wifi.


The first session at Herdla is a 33km baseline. Some random shots from ruins and historic buildings from WW2.
From the survey view you can see preinserted coordinates show only few mm off from where rover is actually located over the monuments. I did not calibrate the pole to be 100% so there might be some error there as well. Anyways, no problem getting fix and hold it. Rover is set with 10degree mask, 5hz, continous mode, glonass AR on, kinematic.


AR value has a bug, doesnt display the correct awesome value.


Next up is 66km marker. This one is way up on the mountains. Close to a regulated water providing electricity power.




And some random shot along the way. Enjoy the rest.
Have uploaded a bunch of clips to youtube, hope you like it.
It was all made in a hurry with a computer that doesnt like to work with 4K video :flushed:


Special thanks to Emlid and all the people there. :heart_eyes:

Definitly. This is just the beginning. Need to get those 4K out in small chunks, its a pain to work with in any way :grimacing:

Question on the AR ratio: your screeshots show AR rations of 1.2 and 1.1, but solution status FIX
For RS+ AR ratio >3 was required for fix.

Was the requirement lowered, for dual freq?
Or is this a result of switching the RTK engine (RS2 is using the inbuild ublox engine rather than RTKLIB, I unerstand), or maybe an issue in the app?

Hi Johannes,

This is an app issue, the requirement for fix is the same

Could you share log files raw data from RS2 Base and Rover?

Yes i could but you would not be able to process it properly before RTKlib has been released with RS2 support.

I want to try with other software like EZSurv. Thanks

I dont think Ezsurv work. But here you go
Its 5hz record and heavy to load.

Thank you so much for sharing.

A small bird tip’d me that latest 2.18.1 will process with Ezsurv…

Such a great news. Could not wait to see what coming for ReachView 2.18 or 3.x. Hopefully Emlid will develop (1) More powerful external radio with 30W power and (2) M2 with multi-frequency like in RS2.

Hi @l3technologycambodia,

Thanks for the request!

At the moment, we don’t have any plans or information about implementing this.

Static or Kinematic ?
