View Full Version : Vantagens between VBOX 3, 3i and 3i RTK

I have some doubts to upgrade my VBOX3.
Someone have a comparative between the 3 models (3, 3i and 3iRTK)???
I saw the comparison paper, but i have a proposal to keep the GPS engine or change the GPS engine.
We can get a gain changing the GPS engine???
Thank you for the help.

I upgraded my unit from VBOX3 to VBOX3i (they kept my GPS engine as it was a later one?). I did this so I could use the IMU as I am always testing in area's where for whatever reason there was always variable GPS signals as shown by pretty poor speed quality.
In my own case it turned my instrument from something that was pretty near useless (as a power measuring device "in the real world") to something that is exceptional now, and so far as measuring in normal or high dynamics with no Kalman smoothing (internal) it is many orders better.
If you can stretch for it I personally highly recommend it :thumbsup: It also got rid of the fault where if you drop out too many satellites that all of the other input channel data would drop out also (real PIA in my case), the VBOX3i does not suffer from this fatal fault (for people like me).
My personal feeling after using both units, I would (for the type of work I do in variable satellite reception environments and wanting at least normal to mostly high dynamics settings) I'd never go back to a unit that did not utilize an G sensor combined with GPS as in the VB3i now.
