Fendt change to Trimble for Varioguide

But it's Trimble! I'm sure there is ways to make a Trimble signal work on green star etc

Again, are you expecting Trimble to make their base work with Green Star or are you expecting Green Star to be modified to accept a Trimble base?

When Robt says his Topcon base works with many brands, even Trimble, why are you not asking Trimble to do the same with their base? Sounds fair?

When I demoed fendt they said my Trimble signal wouldn't work on the inbuilt screen, the same goes for the John Deere 6215 we recently bought with the I build green star screen instead I had to buy a second hand Trimble kit to put on it.

Is this going to change in the future? You pay for tractors with these expensive inbuilt screens the have to spend about 10-20k to get you're own signal working on the tractor!

Lease Jd have unlocked to allow plug and play in to the Deere hardware
More than fendt will do

So I have a Trimble receiver and nav box can that be plugged straight into the screen in the 6215r?

If it was a Topcon agi-4 and x30 straight off your challenger/fendt/mf/valtra/claas/case/new holland it would.....
Sorry but some ask why Topcon is often more expensive than Trimble. This thread with its frustrated owners proves why

Trimble screen and receiver wil plug directly in to the ISO bus of a Deere

But you have to run it though the Trimble screen

You will need a unlock from Deere first

Would be cheaper to run with the Deere system

You used to be able to unlock a Trimble base, but you cannot control who uses it

This is what we have done. Unfortunately with a GPS network all paid for and the fact we need exact repeatability for ctf I wouldn't want to use different signals

I was told today that a Fendt 936 can come with Trimble RTK through SIM card
Can anyone confirm this and explain what's involved
Already getting an RTK signal through modem with fmx and autopilot
Will this offer same accuracy using same signal?

The Fendt website could be more clear on this. My interpretation from the Fendt configurator is that the Trimble receiver comes with an NTRIP GPRS modem as well as with a Trimble compatible radio. This allows you to use your existing Trimble base or a Trimble VRS network via NTRIP.

Accuracy between the two depends on your location. If you are equally far from your base and one of the base nodes of the VRS service base grid, the VRS service should give you marginally better accuracy. In practise the grid is a bit sparse and often your own base would give (marginally) better accuracy. Far away from your own base, the VRS signal would give better accuracy. The network based signal ideally covers the whole country while a private base covers only a small area.

Seems like the Trimble receiver is not able to make use of signals from foreign brand base stations, as usual for Trimble. The receiver however accepts an external modem (like the Topcon based VarioGuide) for other base brands.

This is just my interpretation from the information on the Fendt website, very likely incorrect here and there.

What Trimble receiver is now being offered by AGCO/Fendt? AG-382 from the pics on their website.

Yes the 382 I'm told.

Pheasant Surprise · Feb 24, 2016

Its either so new there's no information on the net about it (can only find the old AG-372 which is CMR only corrections on the internal radio). Otherwise this 382 might be an OEM special/modified for AGCO like the AGI-4 based VarioGuide is?

I was told special OEM model for Agco and only the version available through Agco will work with the system

phil · Feb 24, 2016

I was told Ag 372 today

Robt · Feb 24, 2016

It's not 372

Pheasant Surprise · Feb 24, 2016

So let me get this straight, they are moving to a GNSS receiver only setup (either NovAtel or Trimble AG-382) and the steering control is moving within VarioGuide Light on the Power /7" screen models.

The Profi and ProfiPlus / 10" screen models will continue to be steer ready, requiring an integrated GNSS receiver steering/controller like an AGI-4. Which presumably if they sell you VarioGuide they will still continue to source from Topcon as an OEM?

Northern farmer · Feb 25, 2016

The configurator gives a different impression. Here you can see the options for a 930. Both Novatel and Trimble seem to be available for the Power Plus and the Profi Plus variants (small and larger screen).

For the 700 series the configurator has not been updated and only the Topcon based GNSS options are listed.

Pheasant Surprise · Feb 25, 2016

Good call NF! Forgot about the configurator. Did you run it? As I recall sometimes the options are there but then it comes up with an message saying it will include/exclude other options to make a valid build. Maybe not in this case though.

I understand you can feed it with any receiver, but you will need a Trimble to access a Trimble network

What do you mean by Trimble network?

Quite obviously Trimble Rangepoint RTX and Centerpoint RTX are only available for the Trimble receiver.

My interpretation is that Fendt means "encrypted Trimble radio" when they talk about Trimble networks. I come to this conclusion because the Trmble VRS network via NTRIP/SIM card works with pretty much any NTRIP capable receiver. The current Topcon based VarioGuide RTK can use the Trimble VRS network signal, I cannot see why the Novatel receiver could not use Trimble VRS via NTRIP.

Below AGCO/Fendt explain two RTK radio scenarios, if I understood this correctly. The "Trimble networks" option needs an internal radio which first of all should mean that this is a radio based option and secondly, likely means a Trimble radio integrated to their receiver.

They mention RTK via radio which must be a generic option as it is not linked to any brand. But this option needs an external radio (which must be compatible with the intended RTK radio signal).

Isn't this pretty much the same as for a Trimble receiver under their brand? With the integrated radio you cannot use any other radio except the one from a Trimble base?

"dynamic (pass-to-pass) accuracy +/- 2 cm
for correction signal EGNOS (no subscription needed), ready
for Trimble correction signal Rangepoint RTX (+/- 15 cm,
subscription needed, first year free of charge – registration
needed), Centerpoint RTX (subscription needed), RTK via
Trimble networks (internal radio modem via AGCO Parts and
subscription needed), RTK via Ntrip (SIM with data plan and
subscription needed), RTK via radio (external radio modem via
AGCO Parts needed)"
