"To make my point even clearer consider the following. The TOC says:
(i) real time navigation or route guidance, including but not limited to turn-by-turn route guidance that is synchronized to the position of a user's sensor-enabled device.

is anyone interested in yet another IMU? I ask because I am designing one with 3 axis gyros, 3 axis accel, 3 axis mag, 10Hz GPS, Baro presure sensor and diff pressure sensor, 8 rx inputs, 8 servo outputs, LPC2148 MCU, about 1.5" X 2.5" so far...
Your HDU is incredibly good looking. Did the guys on RC Groups had a look at it ? They could be interested. It is the best I ever saw.
Regarding AP, I'm not a HW/SW specialist, I'm in system control, so more of the maths kind.
There is a lot of competition around AP solutions. Last year I met Bill Premerlani and I helped him develop the DCM algorithm. He designed the UIAVDevBoard with Sparkfun. He is working on a new version, I don't know nothing about it, he keeps the secret :).
I think that he want's to work alone on the HW, it's his baby. You can ask him, he's a nice guy.
I personnaly want to find a more complete AP, that is, the kind you described in your comment. I am still working with Bill because it's fun, I own a UAVDevBoard, and he is my freind.
But unless he adds a magnetometer, airspeed and barometric altitude, my next board will be of the kind you described.
I am having a look around and I found:
Paparazzi (Booz + Tiny 2.11) 500$
Brian Wolfe new version ~400$
These board have about the same fonctionalities as the board you described: 3 magnetos 3 gyros 3 accelerometers, airspeed bormetric alt, GPS
I think that if your board "looks" like your HDU and if it comes up at a reasonable price then I want one and I will try to help you
Thanks for the info on the other IMU/Autopilots. I just took a look and I have to say I am still not too impressed. While they are all complete, they are all expensive and by the time you assemble all the parts they are too big. That is not to say I can make it smaller and cheaper but I think I can. I like Brian's but even his seems a little larger than I wanted.
I have not really put my HUD out there too much yet because the current prototype boards were a little expensive. I designed those to be small but feature rich so I could do whatever I wanted with them. I am currently working on version 2. It will have even more features but will be cost effective enough to sell. I am hoping to have the hardware in limited production in April. The firmware will take a little longer because it will have to be ported from the current system to the new one.
I would like to get an opinion on my IMU/Autopilot intended component list before I complete the design. I wish we could have a few people with some experience with the different gyros and accelerometers weigh in on these before we commit to them.
did you see the post from benjamin1254 here on the Standford University Autonomous Helicopter Project? Here is the Stanford site if you have not seen it and are interested. There are several papers posted on that site, most of which are over my head.
I am pointing this all out because I would like to suggest that if we are going to develop a new IMU/Autopilot we should set our goal on being able to duplicate this ability as much as possible. What do you think?
I don't know if any of the actual details of the project are available anywhere since it seems to have been performed under a Darpa contract but you never know.
I have the Helicopters and can design and build the hardware and can help with writing the software. I am just very weak on the math. We probably lots of genius software gurus that would love to be involved if we are going to do something with this capability.
