Can Trimble be run off homemade base station

[Whit84]

I have bought a tractor with a nav900, Trimble gfx-750 screen and has the ezi pilot pro steering wheel fitted, it’s unlocked to Center point fast but I want to know if I can build my own base station and run the system from that, is it possible? Fist time with gps/rtk so total learning curve. I’d like to use it with rtk but my other idea is to possibly sell the Trimble and build my own.

I run the same set up, works a treat but the cost of the yearly sub for Centre point fast has me looking for an alternative without any reduction in accuracy.

I think unless your Nav900 is unlocked for high accuracy, you will have intermediate accuracy unlocked at present and the Centrepoint Fast yearly subscriptions includes a temporary unlock/licence to high accuracy whilst paying and receiving Centrepoint Fast. So no you cannot use a third party RTK base station or any other for that matter unless unlocked for High accuracy.

The unlock needed is just shy of £3k.

If you sell your Trimble you could use AgOpenGPS which uses RTK as standard with a Keya motor, this could use the same anti-rotation bracket as the EZ Pilot, so very easy to fit, just need to fit a wheel angle sensor.

Could all be done for less than the price of the Trimble unlock!

You can use rtkbase with an F9P for Trimble. See the link in my signature.
