Dear,
I am looking for a GPS-RTK with Dead Reckoning. It’s for a submarine rover application with my students.
What is the difference between the ZED-F9K and the ZED-F9R please ?
On Ublox website i saw that the ZED-F9R-02B is better for slow-moving service robotics. Do you have it or ZED-F9R-01B or ZED-F9R-00B is suitable for my application.
Thanks for your help.
Kind regards.

The F9K has a few more ports/buses broken-out…check the features tab to compare the list.
How is the antenna going to be mounted? They require a clear view of the sky…which wounds tricky with a submarine!
If the F9R-02b is indeed better for slow stuff; the revision #s are firmware variants, the chips are physically the same…you can swap firmware easily via ublox u-center
Russel,
I thank you a lot for your clear and quick answer.
The antenna will be at the top of the system. GPS will be used regularly at the water surface. We plan to dive during 5-10 min cycles.
So the best for my application is to take your F9R-00B and upgrade it to 02B ?
Have a nice day.
Stephane.
Yep 
Great !! Thanks for the support !!!
