We wanted to test how far we could use SMARTNAV’s accuracy down to. So basically what we did was to mount its antenna on the top of the extruder of a 3D printer. We then programmed it to print Drotek’s logo ona few layers. Remember that the size of the hot plate is 20x20cm, so approximately 5 to 50 less than the standard precision of a GPS receiver.
The following picture plots the logged positions along the test, astonishing isn’t it?
And this the comparison between the output of a classical GPS vs SMARTNAV RTK, with the exact same raw data :
