Aron Neagu posted a discussionEnabling airspeed sensor
I am writing a custom firmware for the Ardupilot. I have connected an airspeed sensor MPXV7002DP to the pin A0. I can read the ADC value (approx 520) but using the AP_Airspeed library the result is always zero. I believe this is because somewhere I need to enable the airspeed sensor.Using the Arduplane firmware, the airspeed can be "enabled" and set to "use" in the mission planner. How can I do something similar, but programatically? There are 2 variables in the AP_Airspeed.h file, called…See More

Personal Introduction and Large Scale Quadcopter with High-res imagery
Hi all. I work closely with the Mining Industry as well as the Oil & Gas Industry and see high value in developing a small UAV with LIDAR, FLIR, and other tech. I have a MS in Aerospace with a concentration on Automatic Flight Controls and Artificial Intelligence and want to get some prototypes going. I have stayed out of the game because I found revenue in other ideas (see my LinkedIn). I have…See More

Ajit Krisshna commented on srinath mallikarjunan's blog post DCM versus Kalman filter"Your paper looks very interesting. I will give it a thorough read and see if I can wrap my head around some of the underlying concepts. Thanks!"
Ajit Krisshna commented on srinath mallikarjunan's blog post DCM versus Kalman filter"Thanks for the reply Jeff!
That makes a lot of sense. So the part where we decide "how much" of the accelerometer we want and how much of the gyro reading we want is also decided by the PI gain values?"
"@Ajit
Essentially, the integrated gyro measurements provide the "high frequency" content of the pitch & roll estimates, while an acceleromter-based gravity vector estimate provides the "low frequency" content. The…"

Welcome to DIY Drones!
This is the home for everything about amateur Unmanned Aerial Vehicles (UAVs). Use the tabs and drop-down menus above to navigate the site. (About us/Site rules)
This community created the Arduino-based ArduPilot, the world's first universal autopilot (planes, multicopters of all sorts and ground rovers). The APM 2.5 autopilot hardware runs a variety of powerful free UAV software systems, including:
- ArduPlane, a pro-level UAV system for planes of all types.
- ArduCopter, a fully-autonomous multicopter and heli UAV system.
I'm new to all this--where do I start? Are amateur UAVs legal? (yes)

UAV news from sUAS News
X47 B Touch and Go
An X-47B Unmanned Combat Air System (UCAS) demonstrator conducts a touch and go landing on the flight deck of the aircraft carrier USS George H.W. Bush (CVN 77), marking the first time any unmanned aircraft has completed a touch and go landing at sea. George H.W. Bush is conducting training operations in the Atlantic Ocean. Next stop, the full stop landing amazing. Last Fridays touch and go comes one week after the first catapult launch from an aircraft carrier and was the first touch and go by a UA at sea.

The sUAS News Podcast Celebrates – Dies Natalis
May 9th 2013 marked the one-year anniversary of the sUAS News Podcast Series. We celebrated the occasion (and 200,000+ downloads) by airing a special “Really Big Show”, or episode #48 recapping the highlights and ground covered from the past year’s 47 information packed episodes. http://www.blogtalkradio.com/suasnews/2013/05/08/the-really-big-show The entire sUAS News team takes pride in the popularity of the show and all of the positive feedback. The numbers imply that folks from outside of the UA Kumbaya campfire circle are tuning in to hear about the technology applications and end-user aspirations. The Podcast Series was introduced as an additional content vehicle (manned). sUAS News believes in giving the public what the public wants, and multi-platform information distribution appears to suit this busy and technologically diverse audience. The ethos was to do more than just produce some Cavett-esque interview program, we wanted to try and build a groundbreaking experience. Part of that goal manifested itself by bringing the audience into the field for applications and conceptual firsts. Some, of those live locations are places that most people have only read about or imagined going to in person, and no, I’m not just talking about Vegas. We were all there together as hosts, participants [...]
Unmanned aerial vehicles spur demand for advanced foams
Unmanned aerial vehicles (UAVs) are increasingly in the spotlight in trouble spots throughout the world, but they are also finding increased use in civilian applications. In parallel, suppliers of advanced thermoplastics such as Sabic are addressing demands for aerospace grade materials that meet a number of stringent operational requirements. The UAV market has potential not only for military purposes, but also for civil aviation applications, including First Responder support, wildfire mapping, weather monitoring and telecommunications. It is predicted that, if the opening of the National Airspace to civil UAVs occurs in 2015 as planned, the market potential for UAVs between 2015 and 2017 will be around $13.6 billion according to the AUVSI Economic Report 2013. The U.S. military UAV market is similarly expect to expand in the coming years: a report conducted byMarket Research Media states that the U.S. military UAV market is projected to grow at a 12% compound annual growth rate, reaching $18.7 billion in 2018. The report finds that the U.S. military UAV market will generate $86.5 billion revenues over the period 2013-2018. With this market growth, there is an increasing need for advanced materials that will allow the range of UAVs to be extended and their air time to be [...]
Does Navy drone spell end of the Super Hornet?
By Tim Logan Something happened on the deck of an aircraft carrier off the coast of Virginia on Tuesday that could eventually ripple all the way back to one of the biggest factories in the St. Louis area. The X-47B took off. It was a “watershed event,” said the Navy’s head of aviation, the first-ever launch of an unmanned combat drone at sea. While the Northrop Grumman-built X-47B hasn’t yet stuck a carrier landing — one of the hardest feats in all of aviation — Navy officials think that’ll happen this summer, and they hope that by the end of the decade drones will be a big part of their air combat fleet. All of which raises some big questions about the future of the plane that makes up much of the Navy’s air combat fleet today: The F/A-18 Super Hornet. http://www.stltoday.com/business/local/does-navy-drone-spell-end-of-the-super-hornet/article_93958ff4-3776-5132-aedf-db363c1ee8fa.html Bookmark It Hide Sites
Germany Scuttles UAV Program, According To Reports
Agence France Press is reporting that Germany has cancelled a planned ‘Euro Hawk’ UAV programme because it believes European authorities will not certify them to fly in civilian airspace. More from AFP: Germany had “no hope” of seeing the unmanned aircraft, part of a programme that would have cost more than one billion euros ($1.3 billion), approved for use, said the source speaking on condition of anonymity. The European Aviation Safety Agency has said it would only certify the drones to fly over unpopulated areas because of a lack of an anti-collision system to protect airliners, according to German press reports. “The equipment is not ready for approval without immense expenditure,” the source added.
