Mohamed Zahana replied to Simon Howroyd's discussion Multiple MAVLink Channels (UART)"Ok,
To make it clear:
1- I don't use the normal telemetry port.This is why I said you need to use the ports on the APM "side"
You will find 12 pins in a raw on one of the APM sides, that includes UART0 and UART2.
2- Don't solder…"

"Hi Jamie,
I don't think a brown out was your major cause of problems. As far as I can see the major issues were:
it looks like you have a MTK GPS, and it was having trouble retaining lock
your settings had raised AHRS_RP_P to 0.5, which…"

Michael Pursifull replied to renaud barbier's discussion is goodluckbuy a reputable website to buy APM2.5?"It is a major clone operation. They often don't work. They don't have rights to the name, but use it anyways, and they are known for using out of spec parts, providing little or no QA. All you need to know is in their name."
DeveloperR_Lefebvre replied to Antoine Rennuit's discussion MCU vs RTOS
"Nope. Arducopter on APM is running "bare metal" which means there is no operating system. There is a scheduler running, but it's all hard-coded."
Stephane Rocca commented on Roberto Navoni's blog post VR GIMBAL ( Board Control and IMU ): We are ready for developer."In fact it's a big headake, that has to be resolved on the math side to be affirmative.

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)

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.

Israel is world’s largest exporter of drones, study finds
By Gili Cohen Israel is the world’s largest exporter of unmanned aircraft, in terms of the number of systems sold, a study has found. Over the last eight years Israel has exported $4.6 billion worth of unmanned aerial vehicles, according to a study by the business consulting firm Frost & Sullivan. UAVs, or drones, constitute nearly 10 percent of Israel’s total military exports. Unmanned equipment exports are a relatively volatile market, the report shows. Israel had $150 million in UAV exports in 2008, a figure which increased substantially in 2009 to $650 million. Exports of the small surveillance planes peaked in 2010, a record year for drone sales, to $979 million. http://www.haaretz.com/news/diplomacy-defense/israel-is-world-s-largest-exporter-of-drones-study-finds.premium-1.524771 Bookmark It Hide Sites
