It's available on backorder as all Reach RS receivers are sold out.
Here is the page in shop:
Can you configure your receiver to work with other vendors receivers such as Javad, Trimble, various data collectors?
Reach RS can output/receive industry standard RTCM3 corrections so it should work with receivers from other vendors. You can use NTRIP caster or external radio for real-time communication.

Has anybody actually been able to test this equipment seriously? (when I mean seriously I mean a team of professional surveyors or a university , and not a random guy).
There is a bit of confusion on what kind of accuracy this system provides. If I am correct the gnss receiver is from the company ublox. The ublox specifications mention 2.5cm accuracy for rtk. Some sites mention 25mm accuracy horizontally, and the main emlid site 7mm. So how are they coming up with 7mm rtk accuracy? (7mm rtk accuracy is not even provided form major brands like trimble).
There are a lot of resources where you can learn more about real tests of Reach RS (Emlid forum, Users group on FB). The current specs of Reach RS may be found on its landing page: https://emlid.com/reachrs/.
Ublox has different chips and Reach RS doesn't use one with built-in RTK. Emlid uses own RTK engine.
Feel free to contact in case you have more questions!
The current specs of Reach RS mention 7mm rtk horizontal x2 vertical.
Many dealers, if not all, mention 25mm horizontal accuracy for rtk.
So how is a land surveyor going to take this seriously?
I don't understand what is the difference from using a rtk-engine (rtk-lib).
This is the gnss, reach rs is using.
Page 6, it clearly mentions rtk 2.5cm accuracy.
So doesn't matter what anybody claims.., it will always provide 2.5cm accuracy for rtk.
In comparison a random other gnss receiver company for example.
The company that sells the receiver claims 8mm rtk accuracy. (http://www.southinstrument.com/userdata/UploadFiles/down/2016122171...)
and the gnss mainboard that's on that same receiver has again 8mm rtk accuracy. (https://www.navtechgps.com/assets/1/7/BD930_DS.pdf).
So either its false advertising, or I don't know what.
M8P indeed may have a 2.5cm accuracy for RTK, but Reach RS is not using M8P.
that's good to know.
Is it possible to know which gnss is used on the reach rs instead of the M8P?
