"I am an outsider who has benefitted greatly from the work of this community (while contributing very little) and I'm hopeful that these disturbances damp out over the next few weeks and months. I've read everything people have linked to in this…"
"@Chris_Anderson, Thanks for the Pozyx link. I'll be ordering some of those today!
The little quads swarming at the end of that TED talk look like Crazyflie 2's from bitcraze. My guess is that they are using the DWM1000 UWB positioning modules…"
"I would have a hard time saying that either one of these large swarm demos was significantly harder than the other (comparing the Naval Postgraduate School's swarm of 50 fixed-wing planes vs. the AscTec/Intel swarm of 100 multi-copters). The two…"
"A fast launch rate is important so you can get the last plane up while the first plane still has enough battery left to do something interesting. I see multiple launchers operating simultaneously in their future... :-)
It depends on your…"
"I started to try to order some parts at the beginning of May and could not get the web site to completely process my order. It would charge my card but not create an order number. I started trying to contact 3DR on May 6 and was given a workaround…"
I wasn't involved in this work and I'm not affiliated with the university, but NMSU has had a UAS Flight Test Center with a up and running for a couple of years, at least. You can read more about it here: NMSU Physical Science Laboratory UAS…"
"Gary, I think NASA has a pretty good track record for respecting the intellectual property of others, but regardless, you'd want to make sure you have the proper protections in place before you start demonstrating a technology that is proprietary in…"
"Brent, there are a lot of different pieces to the ADS-B puzzle. Wikipedia has a good overview on this page. Most aircraft in the U.S. will be required to implement "ADS-B Out" by the year 2020. That means they will be regularly broadcasting…"
"It's not as bad as you think. I saw a post here, a few months ago, where a clever person had put together a working ADS-B receiver for $30. We're paying a little less than $3,000 for ours, but they can transmit and receive and they are TSO'd.…"
I just wanted to let everyone know that early registration is open for the UAS Airspace Operations Challenge. Please take a look at the web site (http://uasaoc.org) to see the deadlines (early registration ends Nov 15), the new Team Agreement, and…
The 900MHz ISM band radios (like an XBee or Freewave radio) work between 902 and 928 MHz and the ADS-B UAT frequency is 978 MHz. Have you experienced interference problems between these systems in the past? For Phase 1 of this competition,…"
"First, thanks to everyone for taking the time to read our draft documents and offer comments! I think that your feedback is vital to getting a final set of rules that will foster a healthy and fair competition. In that light, I want to emphasize…"
Since I first posted here about this competition last October, we've been pretty busy. NASA selected Development Projects Inc. (DPI) of Dayton, OH to be our partner and run the contest. We've selected Camp Atterbury, Indiana (in the restricted…
Assuming you ground everything properly, couldn't you power your autopilot from one ESC, your OSD from a second ESC, and your RC receiver and telemetry radio from a third and possible fourth ESC? My vote goes to using a dedicated BEC for all…"
"They use mechanical gyros to stabilize big camera rigs for movies...especially when they shoot from helicopters. The expensive ones have the flywheel(s) spinning in a vacuum and usually take several minutes to spin up or down. I think they spin…"
