Reach RTK as rover for precise farming

Dear Emlid Community,

I am using two Reach RTK modules, one as base and one as rover on a tractor.

RTK correction over TCP works fine,(had struggels with the Wifi connection wih vers 2.6.x), hope this will be solved with 2.10.x, not tested yet), i get an FIX in about 2 minutes.

As tractor guidance tool i use “Cerea” and all works fine.

BUT for accurate steering Cerea prefers 10Hz output data stream from Reach.
With Glonass message sent, reach is only able to send 5Hz. I only get 5-7 good GPS and Galileo sats, and i think these would be a little bit to poor for exact and stable rtk calculation.

Is there any option to test with Glonass on at 8 or 10Hz or may this “overheat” the M8T

Best regards

There is no way to “overheat” the internal receiver. However, it’s capabilities are limited hardware-wise. Even at the rates we provide, it is still operating at a max, so going higher is not an option.

The number of sats you can see seems a little too low, by the way. May there be something wrong with antenna placement or conditions?

OK thanks,

I´ve heard/read anywhere that there is a limit for operation modes with all gnss systems on.

On my base its no problem with 5Hz. But if i drive with the tractor and rover i get approx 12 to 14 corrected sats, almost the half are Glonass. If i drive near to a forest or a hedge it migth be a problem only with GPS sats on.
By the way i will try autosteering on rover only with GPS and Galileo with 14Hz update rate and test if signal is strong an stable.
Pictures will follow…

Beautiful :slight_smile:

I know @Andreas_Ortner is working with cerea. Maybe he can share his setup?

Shure i know. He gave me the tip with reach :grinning: i drove with about 12km/h. Setup isn´t perfect yet, but i will improve. Emlid reach is great :ok_hand::+1:
