Which RTKGPS to try with a rover?

Hello,

I have built a rover using an APM 2.7, Sabretooth 2x32 speed controller, 12V brushed motors.

This youtube video gives a quick demonstration of what it is. It still needs a lot of work! I operate a vineyard on Australia and I hope to develop my machine to be accurate and reliable enough to drive between rows of vines spaced about 3 metres apart. The maximum range of the rover from a base station would be no more than 1000 metres.

The next stage of development is to upgrade to a Pixhawk controller and use a relatively low cost RTKGPS.

I was wondering if anyone would have any advice on which RTKGPS would be the best to try?

I am considering 4 options. (just because these are the low cost systems I am aware of)

Piksi from Swift Navigation
Reach from Emlid
RTKite from North Surveying
Precis from Tersus

I would be interested an anyone's feedback and experience with these systems.

Thanks for your time and for the help this forum has already given me.

Kind Regards,

Stephen
