"Precise Point Positioning (PPP) is a zero-difference technique (i.e. no reference receiver needed) as opposed to RTK, where you need a reference receiver to cancel common errors. in PPP you use precise information of GNSS orbits and clocks and an…"

"PPP?  New one on me.  Is this not to be confused with PPK?  RTK and PPK (Real Time Kinematics and Post Processed Kinematics) GNSS are the ways to do that. For this application, PPK is often superior because real time position is not…"

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…"
