Started this discussion. Last reply by Andrew Girgen Dec 23, 2013. 1 Reply

I'd like to set up a high speed off-road automated vehicle, and my initial concern is whether APM:Rover supports any sort of stability augmentation / ESP / traction control out of the box, or whether…Continue

"They are U-blox receivers,  and HERE is made by Hex Aero and ProficNC (the makers of Pixhawk).  I think they are just reference designs.. "

More info on Here GPS?

Just noticed that the "GPS of choice" for the Pixhawk 2 now appears to be "Here", and that there's an RTK version.  Is there any doco on these?  In particular the RTK?See More

MikeRover commented on Chris Anderson's blog post NASA simulates Phantom airflow
"Rob, the incoming air above the rotor is being drawn in from a larger area at a lower velocity than the air leaving the propeller - the streamtube contracts below the rotor so that you have constant mass flow but increased velocity. The net result…"

"Sportjet, it may be simpler than you think.  Dimension Engineering make some RC (PWM) controlled relays.  Set up the channel on your controller, configure the APM to pass it through, and plug in the relay.   If you need something more…"
