Me too.
You should be fine reading the documentation to modify most of the variables (gains etc.)
Waypoints and such.. I think the config tool would be your best way out.
There is no "User Friendly Code".
However I would agree that Ardu needs a little bit…
Not so much atm.
Pursuing a company about some laser time of flight modules with raw serial output.
Absolute raw readings that is, timings and or calculated distances in plain text.
This is critical because then we can filter the results as we see…
Looks very functional.
Functional is sexy.
Any progress with altimeter?
Can you send HiRe pictures of what is inside ?
Gimbal = pan/tilt mount effectively.
Different gimbals and mount setups have different specifications and thus differences in slew speed, acuracy etc.
IMO the procerus test rig might not be the way to go. It's a flying wing and it looks like it wou…

This website states a typical measurement time of
Aye, the trigonemetry method.
Those this method has it's uses I would much prefer to use a time-of-flight setup.
Much more accurate and alot less sensitive to issues.
I've looked into ideas for a cheap laser range finder, and I think the most cost effective is to use the CMUcam1 ($109) and a powerful laser pointer. Optical filters can be purchased and fitted over the lens of the camera to filter out unwanted ligh…
I believe I saw this tech implemented some time ago when searching for image recognition research papers.
Can't remember the company that did it atm however... mind blank. :(
There would need to be some sort of filtering on the data for use of the IMU in games, the sensors they are using are still incredibly noisy and drifty.
It is possible they implement a kalman filter though I think a simpler solution for most games w…
Read the Ardupilot documentation.

1. Depends, you can use a differential pressure sensor to obtain airspeed. Ground speed can be obtained via GPS.
2. Easy, Barometric altimeter or GP…
Ahh shame you are off but yes I will continue to run the idea through it's paces and see what I can come up with.
You don't necessarily need to use gumstix..
I will run the SweetGPS code through it's paces and see if it could be ported to a MCU.
Onc…

- Hi Joseph,
I guess you must be gearing up for the outback challenge. I drop you a line on your project site last week, I'm now back from holidays and now up and running. Any news on RTK GPS base station, I'm going to start on that next week.

Here is something to think about which I found on the net.
http://sourceforge.net/forum/forum.php?thread_id=2428350&forum_id=821573
"Hi Thomas,
Thanks for your interest. The only way to get sub-meter accuracy is through carrier-phase differential GPS, and this means you need carrier phase measurements to be output by your gps receiver so you can then use something like sweetGPS to find your position solution. Unfortunately, most gps receivers do not bother to output the carrier phase measurements as this adds complexity. Most likely the receivers you have will be of no use in trying to use this code. This code is meant to run in real time, so you may want to try some of the other open source codes (gpstk) to see if they can help you with post processing.
The Superstar II is being discontinued, and this code is being adapted (rather slowly) for use with the Ublox receivers that also output carrier phase measurements. The Ublox are rather cheap < 100$, but the interface to their output needs to be written.
Using two Superstar II boards, you would also need two computers and communication between the two, and you could certainly build an enclosure to protect against weather.
SweetGPS is still under development, although not very actively. It will almost surely get ported to new hardware this year.
All the best,
Steve"
I'm going to contact Steve to see how he has progressed, do you have anything you would like to add.
Thanks Stephen Jack

AeronaUTS:UAV Website now online!
Hi Guys!
Finally got around to getting up some kind of web presence for the team, far from complete and looking a little bare but this will be where to look as development speeds up over the university break. :)

See you all around!

UAV Outback Challenge 2009
Hey everyone!
I will be heading a team of first year students of the University of Technology in competing in this years UAV Outback Challenge. I am sure everyone here knows all about the challenge but if not you can find out more about it @ http://www.uavoutbackchallenge.com.au
Soon I will be starting a build log and sharing our progress as soon as I get our website up and running. :)
I wish everyone else entering the best of luck (especially the Telemasters :P)
