Base Station

Sure PAT.
Both SNIP Lite and RTKLIB can meet your needs. Both are free.
Just one PC with internet connection, one F9P/PX1122R , one UART TTL USB module, RTK antenna is enough for your current requirement,

Hi kcm01 how did you go with auscors did you get Ntrip working after 1st July ? I’m having trouble trying to connect

kcm01 · 25 July 2022 05:19

Hi Vic,

I received an email from Auscors recently the old URL will not work after 31st August 2022.

I then registered for the new Auscors URL using port 2101 but kept getting an unauthorised connection.

This error is because the email address associated with the new username has to be verified as part of the new registration.

I now have the correction stream working Ok but have only tested using SNIP.

Ken.

Dear AUSCORS NTRIP Broadcaster user,

In September 2021 Geoscience Australia released enhancements to our AUSCORS NTRIP Broadcaster platform. These enhancements brought together all the data streams from our contributing networks into a single location and improved the reliability of the service. At the time we informed users that the old platforms would be decommissioned in mid-2022.

We have identified that your account is still connecting to auscors.ga.gov.au and/or tier3.auscors.ga.gov.au. We will decommission these hosts on 31 August 2022.

To access the new platform, you will need to:

register for a new account at
point your systems to our new URL (ntrip.data.gnss.ga.gov.au)
we offer connections on port 443 (preferred) and 2101 (less secure)

If you have any concerns with switching your connections to the new system, or have any issues doing so, please feel free to contact us at .

Kind regards,

Brandon Owen | GNSS Informatics Team Lead

GNSS Infrastructure and Informatics | National Positioning Infrastructure Branch

Space Division

Great thankyou I’ll give it a try

elmosindustries · 21 September 2022 03:06

Did you get it to work? I’ve registered a new account and haven’t had any luck

PotatoFarmer · 21 September 2022 04:38

The more issues you guys have, the more valuable an Emlid M2 looks for base.

Been using their caster with the M2 since February, 100% up time. No static IP, or dynamic DNS required.

alexandr · 21 September 2022 05:24

And what is his price.

NorthernFarmer · 21 September 2022 09:32

PotatoFarmer mentioned the price earlier somewhere. I’m sure the Emlid M2 would be easier for all of us but I’m also sure PotatoFarmer would not have problems with any of the other RTK Base options either. Him having no issues with Emlid M2 would not mean none of us others would not have any issues.

We would purchase auto-steer ready tractors with branded screens if we wanted to avoid all implementation and installation issues and the budget did not play any role. In practise most of us want to find a reasonable compromise between “issues to be solved” and cost. There is no single best choice for everyone. Some want the absolute lowest cost at the risk of issues to be solved, some are willing to pay a bit more to avoid issues. Fortunately pretty much the complete range has been introduced at this forum.

The module by itself is 500US, then get a mcx to sma or tnc adaptor from ali to connect it to a survey antenna. It also makes it really easy to PPP, and also can get a trimble to fix.

I still use breakout boards for rovers, but for base M2 just works, especially with NTRIP using Emlids Caster service.

A trimble R12, that is rated 8mm+1mm/km is only $28,000. It also could be used as a base, that used to be the only way to do it.

I get the challenge for some is to make this setup as cheap as possible. But sometimes cheap ends up costing more in headaches. Compared to 1 years rtk subscription in Canada $1200/year/machine the M2 is a great deal with the same reliability.

Mdmcurt · 21 September 2022 14:20

Will the M2 work with Trimble rovers?

PotatoFarmer · 21 September 2022 14:25

Yes, Verified.

It will fix a trimble rover, it has the 1008 message enable on a checkbox.

Mdmcurt · 21 September 2022 14:43

Would the Bd970 work as a receiver on a Trimble auto steer setup instead of the 372 units? Does it send tsip

PotatoFarmer · 21 September 2022 14:51

That is a really good question.

I will look again but I think it only does trimbles new standard GSOF. But it will pump out GGA at 50hz.
It also has a CAN port so more research is needed.

Went back to the F9P shortly after this video, the Trimble worked great in open sky conditions but just could not compare to the F9P in obstructed areas.

elmosindustries · 21 September 2022 20:37

Have you got auscors working with aog? Ive just ordered lora radios but am interested if auscors will still work

I put up a full tutorial on how to deploy rtkbase on a raspberry pi with ublox here:

# FreeRTK
## How to set up your own RTK base station

OK, about time I got writing this stuff down. This is from the point of view of someone who wishes to set up their own base station. It's a lot simpler than you might think, if you can get past the hurdle of finding the little computers in stock that is...

---
## But, before we go any further - what this is, and what this IS NOT

### This is documenting how to set up an rtkbase station, and provide free RTK correction data to yourself and the local community. Nothing more! It is absolutely NOT a way to get free unlocks for centimetre level accuracy for your machinery. It's not a way to save you thousands in doing that. It's a way to potentially save you hundreds, per machine, per year for the RTK subscription tho. Also, you might well need to provide your own SIM card if that's how your system works. You can get data-only SIMs with 2gb allowance for a fiver a month, and some systems like FJ Dynamics, can use your phone as a hotspot, so you won't even need a SIM card.

---

### Still here? Good, but before you think about buying a base station kit tho, you need to consider:
- is it really necessary? Is there more than enough coverage in my area?
- if I'm buying it primarily to support my vehicle, do I know for a fact it will work with it?
  - at time of writing, this works with Case IH Trimble, FJ Dynamics, AgOpenGPS and (with a different [message set](messagesets.md)), John Deere. John Deere are a bit of a nightmare tho, they don't make life easy. Consider yourself warned there...

So, onto the steps then !

In light of above, I’ll write up how I got the rpi to use ddclient to update dynu.com for nothing, and without that pesky renewal thing that no-ip make you do every 30 days…

Cat_Doctor · 21 September 2022 22:01

Do we have setup instructions for RTK corrections being sent over radio rather than WIFI/Internet?

alexandr · 21 September 2022 22:31

m_elias · 22 September 2022 01:13

You would have to reference the radio’s setup guide for that. The transmitter input baud needs to match base station output baud and the receiver/rover need to match each other.

kcm01 · 22 September 2022 01:11

AUSCORS cor sites work OK. Their URL has been changed to ntrip.data.gnss.ga.gov.au. It now supports encrypted data using port 443. It still works with unencrypted data using port 2101. I think AOG only supports using port 2101.

elmosindustries · 22 September 2022 04:01

Just got it going now. In ntrip client settings under the advanced tab I had to change the http from 1.1 to 1.0
