Arduino Mega based UAV Autopilot

Hello Everyone,

Objectives

I am new to autopilot development and I want to build an autopilot based on

Can you help?

Can someone point me to the right direction for the following;
  • How to fuse all the IMU+GPS+Airpressure sensor data together to estimate UAV's state (its position, orientation, velocities and accelerations)?
  • How to create a "realistic" UAV flight dynamic model of a popular UAV airframe (such as Mutiplex EasyStar ) for simulation?
  • How to decode multi channel PPM signal from a RC receiver using Arduino Mega?
  • How to tune PID controller for throttle, elevator, aileron and rudder?

The longest flight time you had with your EasyStar

Posted on August 15, 2009 at 3:55am 6 Comments

Dear DIYDronians,

What is the longest flight time you had with your EasyStar using additional batteries?
What is the MTOW for EasyStar?
How much extra weight (extra batteries) it can carry?

Thx

Accurate 3D CAD model of the Multiplex Easy Star

Do you know if there is a publicly available 3D CAD model file of the Multiplex Easy Star (preferably an accurate)?

Ardunio Mega code to read MicroMag 3-Axis Magnetometer

Posted on April 25, 2009 at 11:23am 0 Comments

We can calculate the UAV heading (flight directions) from multiple consecutive GPS readings if the UAV is moving. However, for a hovering, this method would not work and we may need a magnetic compass or a magnetometer (like MicroMag 3-Axis Magnetometer from SparkFun).



Is there any code out there for… Continue

Attitude determination using multiple GPS receivers

Posted on April 20, 2009 at 3:08am 1 Comment

Is it possible (how) to determine UAV's attitude (orientation) using multiple (two) low cost GPS receivers (like those on SparkFun's GPS page) ?

Climb or decent to altitude and altitude hold using pitot/static sensor suite

Posted on April 19, 2009 at 2:42am 6 Comments

GPS receivers (without DGPS or WAAS corrections) do not provide accurate altitude information. In order to maintain accurate altitude, a pitot-static may be used.
Is there anyone in this DIY Drones network who used a pilot-static sensor suite for his/her Ardupiloted UAV?
