Portable All Constellations Triple-Frequency RTK Receiver/Base for $1899

In a not completely unexpected development, Emlid, the guys that make the single L1 frequency Reach RS and Reach RS+ have now released this....

https://reachrs2.emlid.com

Reach RS2 triple-frequency L1/L2/L5 multi-constellation (GPS, GLONASS, Galileo and BeiDou) ruggedised receiver for the equivalent of roughly £1,500.

To put that into context if you were going to buy the equivalent portable RTK base (or rover) from Topcon or Trimble (or any of the other major players) it would cost you 4 to 5 times as much!

Looks like it is only a 900 MHz internal radio. Would need an external 450 MHz radio or am I missing something.
Yep. You'd need to connect an external UHF radio (either serial cable or bluetooth) if you were wanting to send corrections to another rover (tractor) with a 450 UHF radio. The internal radio is their own properitery LoRa implementation/protocol which isn't compatible with 450 UHF.
 
Could you set this up to send out NTrip to tractors that are fitted with modems then?
Yes. However to be a pedant, NTRIP is “pulled” from the rover (tractor say) from an NTRIP caster, rather than “pushed” (sent out) to the tractors/rovers.

Now you could setup the Reach to be an NTRIP caster connected to your home WiFI network, and then if you had a static/public IP address on your broadband router connection (and port forwarding setup) - you point your tractors receiver to that IP address for its NTRIP connection onward to the Reach caster.

Alternatively if that all sounds too hard, or not possible due to your broadband setup, then within the aid of a free NTRIP caster like SNIP you could achieved the same.

Does that all make sense, or have I lost you?

I think I understand the how, it would just be the getting there! If that makes sense! I like NTrip because I get correction everywhere. I will defiantly look closely at this product.

I think it would come down wether or not they have good backup. I think I might email them and see what like there response is like!

As an owner of two first generation Reach RS units, they haven’t really required that much “backup”.

To be fair Emlid have been pretty responsive when I’ve had questions and there is a thriving online community of Emlid users from all walks of life and all industries. So I wouldn’t be too worried about that angle.

Emlid are also on TFF so you could fire away any specific question via PM I suppose and see what they say or visit their online forum as said; https://community.emlid.com/
 
Hi everyone,

Dmitriy from Emlid here.

@Pheasant Surprise thanks for posting the news on TFF!

We will be happy to answer all the questions on how to integrate Reach RS+ or Reach RS2 for precision guidance or auto steering.

To get the reply quicker I'd recommend posting Reach-related questions on Emlid forum or contact us directly via our website. We usually reply within 24 hours, however, now it may take a little longer as we have a lot of requests last few days.
 
Could some list an itemised list of everything required to convert a non auto steer tractor, the cheapest/simplest way possible?
To be clear, this is not an autosteer controller, it’s simply an RTK capable receiver.

If you want to have a look at DIY autosteer setup @Briantee has a project in the works. He has recently announced (above) a circuit board for autosteer and section control.

See his thread here for some details.
 
i'm afraid someone would have to explain this to me in a step by step fashion, this unit is like a rtk unit not something you fit to the tractor roof?
Sort of ;) The Emlid Reach RS units are basically GNSS (or simply commonly called GPS) receivers. Nothing more, nothing less.

You could certainly fit one to a tractor roof and folks have done that, however it’s not going to do anything without either a screen or a steering controller and autosteer setup if it’s steering you’re after.

To get RTK levels of accuracy the unit acting as a ‘rover’ in RTK language also needs a correction signal either from another unit acting as a ‘base’ using the internal radio or via another third party source. This could be via the inbuilt 3.5G modem with SIM card connecting to a mobile network / NTRIP or you could attach an external UHF radio to the receiver and connect to a third party RTK provider or neighbours RTK base.

If you need a brief explanation of the basis of technology there is a summary on the Emlid website here. Alternatively I’m quite happy to write a little primer on here, but without wanting to teach granny how to suck eggs you’ll need to let me know what it is you want to know.

Hi Dmitriy

A suggestion here, but what would be really useful for the agri precision farming market (and probably survey too) was if Emlid released a simple external LoRa radio that had an RS232 serial port interface.

Basically the style of thing would be the equivalent of a Satel / ArWest / PacCrest 400 MHz radios that we use on machinery to receive corrections from a local RTK base - either portable like yours - or a fixed base blasting out corrections on UHF.

....except it would be using LoRa as the protocol instead of the usual protocols above.

What do you think?
