Philipp Oettershagen commented on Philipp Oettershagen's blog post Tackling the European refugee crisis with solar-powered UAVs: A fully-autonomous Pixhawk-powered 26-hour Search-and-Rescue flight
"Hi Sam

good to hear from you! I am just trying to push back some code to one of your repos - NOT to the ardupilot one (because as mentioned, we use the Pixhawk firmware) but to your simulation repository at https://github.com/samuelctabor/Soaring…"

Philipp Oettershagen commented on Chris Anderson's blog post Pixhawk-powered solar plane sets new endurance record: 81 hours!
"@Patrick:Tom was mostly right: For a low power consumption, the most important thing is that the aircraft flies at its optimal-power airspeed (ca. lowest sinkrate). You can read this paper to learn how we found this airspeed. In addition,…"

Philipp Oettershagen replied to Jean-Jacques's discussion Tuning parameters for thermals
"paul riseborough said:

The TECS algorithm has a control parameter labelled TECS_SPDWEIGHT which controls the ratio of speed and height error affecting the demanded pitch angle. If TECS_SPDWEIGHT is set to 2.0 then the demanded pitch angle is…"

"@Chris Jackson:
Is this publication of any help? That publication is about the 28-hour flight last year, it should answer your motor questions and hint towards the optimal airspeed. The exact optimum power airspeed is of course a bit changed for…"

"@Jesus A
Actually, the code managing the thermal updraft tracking is a port (and extension!) of this http://diydrones.com/profiles/blogs/ardusoar-cross-country-x-plane-... here to Pixhawk, and yes, our plan is to push that back to the main repo if…"

"@Rana: We are using the Pixhawk Autopilot Hardware, and are actually using a custom (i.e. developed at the Autonomous Systems Lab of ETH Zurich) firmware forked from Pixhawk that includes our own state estimation, control and thermal updraft…"

Hi everybody,some of you might remember the 28-hour and 81-hour solar-powered flights (the world record in flight endurance for all aircrafts <50kg) by our Pixhawk-powered AtlantikSolar UAV that was presented here at diydrones last year. This year,…

Philipp Oettershagen commented on Chris Cloutier's blog post New solar UAS record.
"I guess you were not that far off... note that the aircraft presented in that (slightly outdated) paper is AtlantikSolar 1 (AS-1, which "only" did a 12 hours flight), whereas the 28 hour and 81 hour flights were done by AtlantikSolar 2. Main…"

"@Quadzimodo: Great guessing ;) See this paper for the exact solar-panel & battery setup.
@Jake Stew: The term "perpetual endurance" is used commonly in solar-powered UAV literature. The precise expression would of course be "energy-wise perpetual…"

"Hi everyone, thanks for all your encouraging comments! It's great to have the DIYDrones/Pixhawk community here, we owe a lot to this!
Note that to make access to detailed technical information about the plane easier, we have now added a link to the…"
