"I'm using a cheap one from ebay MMA7260, but a easier to connect one would be ADXL330. If you want to have good ones, sparkfun is full of them. Please inform if you make any progress."

You mentioned that you used an Accelerometer on your previous message. Which Accelerometer were you using? I am looking for a two-Axis if you know of any with simple installation process. I am tying to test the accuracy of the result I…"
Akram Habib commented on Akram Habib's blog post Tilt Error Compensation"ok,
very little progress but getting there...I have managed to tilt correct the CMPS03 mechanically during pitch only... I am not sure how to do the "roll" correction as the reading on the East & West direction is not liner!!!
also I…"

Akram Habib commented on Akram Habib's blog post Tilt Error Compensation"Hi Pekka,
Indeed its a tough one, I am having a hard time with it. Thanks for the links tho, which I have already seen two of them...
That is my aim once I have completed the project, I will post the results and the codes I have used. I am using…"
Pekka Ahola commented on Akram Habib's blog post Tilt Error Compensation"Hi, I tried to do two tilt compensation with just the two axis CMPS03 and a 3-axis accelerometer - but I failed miserably :)
Here's the paper I used as my starting point: A Calibration Technique for a Two-Axis Magnetic Compass in Telematics…"
Akram Habib commented on Akram Habib's blog post Tilt Error Compensation"Hi Simon,
My goal is to get the compass operational during all manoeveurs. my findings through the research i have done and the little knowledge I have is that I need to resolve it through "Electronic-gimbaling". (Just out of interest has…"
simonl commented on Akram Habib's blog post Tilt Error Compensation"Hmmm; as far as I'm aware, the CMPS03 will ONLY give accurate compass (direction) reading if it's kept horizontal - that's why you're seeing 'flickering' during tilt.
I'm not sure what you're trying to do,…"

Hi,
First of all I many thanks to Chris for directing me to the right link, which has enabled me to have an enormous understanding to what I needed to do and gained other info that I was not aware of...Brilliant Forum!!!
Right now I am working on the CMPS03 digital compass. I have managed to get the compass programmed and it works fine on the Horizontal/Yaw manoeuvre. I am working on the till error compensation right now (Pitch & Roll). However, I am struggling… Continue
