JPerin commented on Thorsten's blog post u-blox M8N - ground planes, antennas and positional accuracy
"We have tested several antennas and we found no improvement with the 6mm. So why pay more? :-) Our GPS modules are used by all Ardupilot and PX4 team since many years. If you are looking for the best price/accuracy ratio, don't hesitate. "

" JPerin, I understand that, but the question is more about Why 3mm thick instead of 6mm thick - Initially you have used 6mm thick one, and CSG have gone from 3mm -> 6mm thick one (you have made an opposite decision).I'm interested in…"

"JPerin, why Drotek uses 35.3 antenna on their latest GPS, instead of taoglas 35.6.a.02 antenna (originally used on XL version with 80mm ground)? And also XL used to be with 80mm plate, now that is XXL and XL is with 50mm - I would appreciate if you…"

"@Drotek by "TinyRTK can otherwise be used with a dedicated datalink" do you mean it works with the Drone Edition as well or only the normal version? I am asking, because I only see one UART JST-GH port on the Drone Edition. "
