Build Quadcopter For UAV dxAutopilot

Currently being festive air in the form quadcopter robots. I greatly admire robots since childhood and was always curious about the robot. when I know my friends from university my country. then I was moved to make quadcopter.

This I do not Alone, I still helped by my friend Hadi Prayoga (Songky) to build the framework of this quadcopter. we are build Quadcopter used allumunium and use AXI motor with 60A ESC

While this framework is already in 75% Done. we are waiting Quadcopter Control Board that I bought at a price of $ 14.99 Hobbyking.com.

Perhaps this QKB Another week is coming, I can not wait to Fly with this Quadcopter. while waiting, we were trained to fly
quadcopter using a simulator of AerosimRC .

The plan, if this quadcopter successfully flown, I'll switch to quadcopter as a vehicle For fly dxAutopilot.

UAV Ground Control Station Visual Studio 2010

Now I plan to make a ground control station that was built from Microsoft Visual Studio 2010, I am using c # language. net, it's very different from VB6. While this is my process for making GCS was up 60%. 

Microsoft Visual Studio is a complete software (suite) that can be used to perform application development, be it business applications, personal application, or application components, in the form of console applications, Windows applications, or Web applications. Visual Studio includes a compiler, SDK, Integrated Development Environment (IDE), and documentation (generally in the form of the MSDN Library). The compilers are included in the package include Visual Studio Visual C + +, Visual C #, Visual Basic, Visual Basic. NET, Visual InterDev, Visual J + +, Visual J #, Visual FoxPro, and Visual SourceSafe. 

Microsoft Visual Studio can be used to develop applications in native code (in the form of machine language that runs on Windows) or managed code (Microsoft Intermediate Language in the form above. NET Framework). In addition, Visual Studio can also be used to develop Silverlight applications, Windows Mobile application (which runs on top. NET Compact Framework).Visual Studio has now stepped version of Visual Studio 9.0.21022.08, otherwise known as the Microsoft Visual Studio 2008, which was launched on 19 November 2007, addressed to the Microsoft platform. NET Framework 3.5. The previous version, Visual Studio 2005 is intended for the platform. NET Framework 2.0 and 3.0. Visual Studio 2003 is intended for. NET Framework 1.1 and Visual Studio 2002 is intended for. NET Framework 1.0. Versions mentioned above are now known as Visual Studio. NET, because it does require Microsoft.. NET Framework In the meantime, before it appears Visual Studio. NET, there is a Microsoft Visual Studio 6.0 (VS1998). (Ref: Wikipedia) 

I have the ease of using this language even new knowledge about the serial interface in Visual communication is. so I'm sure my program is more powerful than VB6.Why do I use C #. Net (csharp) and not Vb.net?At first I use vb.net, but because I am still just learning (beginer) in VS2010, and at that point I did not get the look of monitoring vehicle behavior such as horizon sensors and others shown in the visual display, and I get the instrument control of Avionics built in C #. since then I use this programming language.

Heading Test UAV

UAV Heading is calculated by gps Data. Using Curent and Last Position of latitude and longitude , it will have result the heading. many formulas explained how to calculated heading, and i'm using hevarsine formula to calculate this heading. i got this formula from this site : http://www.movable-type.co.uk/scripts/latlong.html
And it's simple to use. i calculated the heading on Microcontroller Atmega644p, on interupt routine.

I have test this formula and you can view at my Video below:
