will the ahrs code work indoors without GPS? I get a lot of drift when i run it without GPS. IS that a APM1 problem or have you solved it someway?

Magnus replied to Shyam Balasubramanian's discussion GYRO DRIFT Compensation: "How To" in APM?"Hi Shyam,
I just posted a question about the same problem. I am running the AHRS test and get the same kind of drift you are experiencing.
Did you find a solution to your problem?
Regards
Magnus"
Magnus posted a discussionDrift in APM AHRS test on APM with oilpan
I am running the AHRS test that comes with the AHRS library. I'm using the APM 1 with oilpan. Everything works fine but the angles are drifting. Something like 10 degrees per minute when it is worst. I have tried with two sets of hardware with the same result. One with compass and one without. No GPS attached.Should i not get a stable reference without GPS?/MagnusSee More

DeveloperJohn Arne Birkeland replied to Magnus's discussion APM PPM encoder problem
"The first half of your programmer log is from setting new fuse values (-U lfuse:w:0xe2:m -U hfuse:w:0xd9:m) that will not work with the 328p as it is used on the APM1."
Norman Sanchez replied to Magnus's discussion APM PPM encoder problem"ok, but do not change the fuse, I will try
thanks"
DeveloperJohn Arne Birkeland replied to Magnus's discussion APM PPM encoder problem
"Hi.
Your 328p AVR fuses are wrong. You should not change fuses unless you are sure what they do. You can easily make the chip unusable with the wrong fuses set.
Use the following fuse values for the 328p chip:
Low fuse: 0xFF
High fuse: 0xDF
Extended…"

One of those bad days...

For the last week i have successfully flown my Twinstar with the APM. Everything was tuned and i had developed a good routine for setting things up in the field before flying. Yesterday the plan was to test a long endurance flight (25 min) that also used the relay to reset the XBee to keep the telemetry link for the entire flight.
But this is what happened...
The Twinstar comes with a small PCB that houses connectors for the motors and ESCs. The motor…

Results of first IMU flight tests

Today i made my first tests with a Gyro/accelerometer stabilized airframe. The system is based on an Ardupilot board and the Ardupilot expansion board with an additional gyro. The software is my own, but the Kalman filter is based on code published at the Sparkfun forum.
The airframe is this 150 cm span flying wing:
In stabilization mode the ardupilot reads elevator and aileron input from the transmitter and uses this input… Continue
