So after endless hours in the lab I am happy to report success in all fronts of the autopilot and making the GIT repository publicly available. The project's website
has been updated to reflect the new… Continue

The most basic autopilot you can buy is the UNAV PicoPilot N
, which is basically just a one-axis gyro and a GPS, with an old Pic processor inbetween. It's a "turn-rate leveler", which is to say that it… Continue

If I understand right, Ardupilot is dependent on FMA for roll and pitch stability.
I have 6DOF IMU from Sparkfun and I want to use it to monitor the roll, yaw and pitch angles of my model airplane and use this data to perform FMA functions i.e. maintain roll and pitch stability.
Sparksfun's 6DOF IMU gives accelerations and gyro data. On benchtop experiments, I can accurately measure my roll and pitch angles using only accelerometers. But, if the IMU flies in model… Continue

Many people are using Ardupilot on easystar airplane.
What other airplanes are being used with Ardupilot and how to adjust Ardupilot code for the athoer airplanes?

Hi everyone, I'm new to the community though I have been keeping an eye on this project for several months with the hopes of integrating it with my ROV Project. Last week I finally ordered my initial load out of Ardupilot gear. For starters I'll explain my project and my goals.
My project is very different from anything I have seen using Ardupilot of course I could be wrong and if I am thats going to make my life easier :) My project is a PC Based Tread-Based ROV Chassis (more… Continue

Here's a video about the University of Alaska's operation of a Scan Eagle UAV I posted about earlier:
"Earlier this month in Alaska, a 40-pound Insitu Scan Eagle saw duty fighting wildfires after dense haze grounded conventional aircraft. The UAV is operated by the University of Alaska, which according to university officials is the… Continue

I am sorry for a late , but lastly I had really lot other problems so no time at all for any "flash" work .
However I made few lines of code to made possible communicate sending to OSD from any external devices , so from Ardupilot also - anyway that was the base reason . HappyKillmore already wrote about it - but here detailed descryption of message format .
So we can deliver information to display on OSD at location x,y looks like that :

Hi all, i had to make little changes in program to get the data at 19200 baud rate...... so its all woking with wireless telemetry.. But the only problem is groundstation... how to change baud rate of ground station. Since its in labview so facing problem of changing its baud rate i have its source code also but cant get how to change.. ..or is there any software emulator to get data on 19200 and reproduce on other serial port at 57600 for GCS.. Suggestions please ..

While flying my model UAV, I want to log sensors output and GPS data.in to memory cards. Sparkfun offers two data logger products;

Logomatic v2 Serial SD Datalogger sku: WIG-08627
I want to ask if… Continue

A number of you had sensor calibration questions, so I asked Jordi, to get the answers straight from the source:
1) Are the sensors calibrated only when the bind plug is on or also with every reset?
Only when you insert the bind plug, then it will be recorded in the eeprom. If you restart you don't have to calibrate again (in short periods of 15 mins, battery change for example).
2) Does the sensor calibration happen after GPS lock or… Continue

LCROSS IMU malfunction
It just shows how even for the pros, something as basic as the IMU & AHRS can still ruin your day. You think it's just a matter of pimping a couple trillion dollars from the slaves, buying a super expensive AHRS to do something that's been done for 60 years & moving on to more important things like trajectory design. This is the stuff hobbyists struggle over, not… Continue

There are many small, off-the-shelf boards which can accept TTL or RS232 serial data and control/drive multiple RC servo motor. What I am looking for is the reverse of this operations. That is, I want to measure multiple servo pulses with one small unit, and send the measured values via a TTL or RS232 port.
Do you know if there is any small, off-the-shelf solution for… Continue
