Here are two sucessful logs of a Loiter the first being Loiter and the second a mission flown in Auto..Whilst analising the logs you can see that the loiter drifts off and the apm follows it almost precisely to correct the drift. Now in the Auto looking at the log it appears that the apm does nothing in regards to correcting the drift? but from where I was standing it looked very controlled?

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)
This community created the Arduino-compatible ArduPilot, the world's first universal autopilot (planes, copters of all sorts, ground rovers). The APM 2 autopilot hardware runs a variety of powerful free Arduino-based 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)

Successful Shrike Re-Maiden

We successfully re-maidened the Shrike! Turns out that our elevons had excessive throws, we had insufficient expo's and the wing mounted too far to the nose causing a tail heavy environment.

Egypt: Nation Produces UAV in Cooperation With China
Chairman of the Arab Organization for Industrialization, Hamdy Weheba said that Egypt has started the second phase to produce 12 Egyptian unmanned aerial vehicles (UAV) “ASN-209″ in cooperation with a Chinese company. He added that the local manufacturing in this plane reaches nearly 99.5 percent. Weheba noted that the first phase has produced 6 aircrafts of this type. He stressed that the organization, in cooperation with the Chinese company, succeeded in the manufacture of 120 advanced training aircraft of the type “K-8″. Details of the platform from the ASN site. ASN-209 UAV System is a multi-purpose UAV product with mature technology. Via data link and ground control subsystem, ASN-209 UAV can perform aerial reconnaissance, battle field survey, target location, destroy validation and artillery fire adjustment in day and night in real time. ASN-209 UAV System is consists of aircraft, airborne mission payload, GCS, launch and recovery equipment. ASN-209 uses digital flight control and navigation system, its flight control mode has manual, program and emergency control.It wasGPS and data link to locate the aircraft. The system operation is easy to master. ASN-209 uses rocket booster launch, parachute recovery, no need to use the airport makes the system operation flexible. GCS adopts [...]AUVSI Rejects Calls For Unlawful Destruction Of Unmanned Aerial Systems
In a statement issued on May 18, the president and chief executive officer of the Association for Unmanned Vehicle Systems International (AUVSI) Michael Toscano responded to recent comments by media pundits and television programs that seem to advocate shooting down domestic unmanned aerial vehicles. The coming wider use of UAVs in the U.S. has drawn protests from privacy and civil rights advocates because they say it is intrusive and possibly dangerous. On May 16, syndicated newspaper columnist and Fox Television commentator Charles Krauthammer called for a ban on the vehicles and intimated that others with similar beliefs will shoot the aircraft down and become heroes. “I would predict — I’m not encouraging, but I would predict, the first guy who uses a Second Amendment weapon to bring down a drone that’s hovering over his house is gonna be a folk hero in this country,” said Krauthammer on a May 14 panel on Fox New’s Special Report. According to AUVSI, a recent episode of NBC’s television show “Harry’s Law” also portrayed its main character shooting down a “drone” in just such a situation. Toscano called such talk irresponsible and that vigilante approaches to the vehicles could have dire unintended consequences. “To advocate [...]UAV Flight Training and Simulation Market Worth $451.9m in 2012
Visiongain’s analysis indicates that the UAV flight training and simulation market will reach a value of $451.9m in 2012, as increasing demands for UAVs around the world drives the creation of formalised pilot and sensor operator training and simulation apparatus. A Visiongain analyst commented that: ‘Growing requirements for UAVs will lead to continued demand for more immersive operator training. This will result in spending on UAV flight training and simulation products and services continuing to grow over the coming decade’. The report contains 102 tables, charts and figures that quantify and forecast the UAV flight training and simulation market. Visiongain provides forecasts for the period 2012-2022 in terms of value (US$) for the UAV flight training and simulation market. In addition, the report quantifies, analyses and forecasts 15 leading national UAV flight training and simulation markets from 2012-2022 in addition to providing rest of the world figures. The report profiles 20 leading companies operating within the market, and includes interviews with L-3 Link Simulation and Training, a major US technical systems and service provider to both the public and private sector, CAE Inc, a Canadian company specialising in the provision of modelling, simulation and training, and Israeli Aerospace Industries (IAI) [...]New Scientist:GPS loss kicked off fatal drone crash
This single incident might well put the integration of civil UAS into American airspace back by several years. Paul Marks, senior technology correspondent In a statement supplied to New Scientist, Schiebel says it’s Camcopter S-100 drone, a 150-kilogram rotorcraft capable of 220 km/h flight, should have coped in any case because GPS can be lost for many reasons, such as an inability to access the positioning satellites due to obstruction by high buildings. The Camcopter has multiple inertial measurement units that “allow safe operation and recovery in the absence of GPS signals” the firm says. “All information recovered to date indicates that after a loss of GPS signals to the aircraft’s receivers incorrect handling and omissions over a time period of a number of minutes, resulted in an unfortunate chain of events that ultimately led to the crash,” the statement says. Emergency procedures “to ensure a safe recovery in such a situation” do not appear to have been “correctly and adequately followed” it alleges. The Schiebel aviation engineer who died – a 50-year-old Slovakian with much experience of the technology – was assisting two remote pilots working for one of Schiebel’s South Korean partners. He was not in control of the aircraft, the firm [...]Drones: Unmanned, but Inherently Governmental?
U.S. Air Force Captain Keric D. Clanahan has written a paper on the legal and policy controversies surrounding the Air Force’s use of unmanned aircraft systems (UAS), more commonly known as drones. Specifically, Clanahan examines the kinds of tasks contractors are performing in the Air Force’s drone program and discusses whether these tasks should be entrusted to contractors. Drones have profoundly changed the nature of warfare in the last few years. The drone program greatly depends on private contractors, from drone manufacturer General Atomics to the hundreds of employees of companies like SAIC and BAE Systems who help the Air Force conduct drone missions. According to Clanahan, the U.S. military’s fleet of drones has grown from 167 in 2002 to over 7,000 in 2011, and the Air Force plans to acquire hundreds more over the next few years at a total cost that will exceed $20 billion. Clanahan argues that government personnel should perform many of the roles necessary to sustain the drone program because they are inherently governmental functions, or functions which must be performed by federal civilian or military employees. Clanahan is somewhat vague about whether contractors in the program are performing or have performed inherently governmental functions, [...]UAV news from Flight Global
