RE: [Paparazzi-devel] Paparazzi Won UAS AUVSI Competition

Ok I understand.

Microstrain Gx2 has the angle attitude output

I have find also interesting the Xsens Mti and the Crista IMU

Maybe try one of those

The Microstrain Gx2 have also the angle attitude output, right?

I haven't updated my stuff on our team website for a while.

Rui is correct. Actually, u don't have to stick to Microstrain Gx2. U can get any IMU with angle attitude output, e.g. Xsens Mti-g. The reason we use gumstix is that Tiny only got two serial ports, one for modem and one for GPS originally. So we decide to feed both IMU data and GPS data to that serial port originally for GPS. Take a look at my code, u will understand it.

The Microstrain have already the Kalman Filtering algorithm inside. I think he uses the Gumstix to grab the information from the IMU and GPS and send it to the tiny. That's what I understand. I'm also interested in this solution. I'm trying to develop my IMU. But my kalman filter have a lot of problems. Maybe I will have to ude the Microstrain GX2. Any help will be appreciated.

Though I am working on a cots imu may I ask you this question:

The Microstrain Gx2 has a sensor fusion algorithm. Why do you note in your site that you are have a Gumstix with Kalman Filtering? And more over since I have no programming experience in Gumstix what protocol have you used? Can somebody do the same with an LPC?

We already put our pprz code on the svn. check paparazzi3/doc/OSAM_IMU/readme_pprz_osam_imu.txt.

But I haven't got a chance to write a wiki page to explain it and release our code on gumstix yet. The gumstix code just collects data from IMU and GPS and pass it to the TWOG in a protocol defined by us. I will find a time to do that this summer depending on my workload.

That is so great. Open source again beats out proprietary. Having competition with many vendors is a good thing though. I also agree the Paparazzi community as a whole has won. I am reading the details on the OSAM site now.

Does anyone know if the code for using an IMU will soon be in the SVN repository? I will be building the booz IMU soon and would like to use it with a wing or funjet.

Congratulations again, well done.

Thanks for forward this news, Daniel.

To David's question, Utah State is the only paparazzi team this year. Such a pity that university of sherbrooke could not come this year.

Most of the other teams use expensive Procerus Kestrel or Piccolo autopilots.

The honor goes to all paparazzi forum too.

Congratulations Daniel and the whole team.

I am curious to know what other positions did Paparazzi place?
