"From their website: "The measurement distance range shall be up to a few meters with a target ranging accuracy of better than 1 mm".
Still a good replacement for ultrasonic sensors..."

"There is one here now (as seen on Px4 Q&A site) "
"I would vote for Java for the following reasons:
- It has the biggest developper's community
- It is truely cross-platform ( You could also have a J2ME flavor for mobile devices)
- There are loads of very good free IDEs available (eclipse, netbeans,…"

"You might want to look at PNI micromag which is supposed to have a better resolution.
Also, a wide scale magnetic model is freely available (see WMM here). Although there certainly are local variations, the magnetic field is supposed to remain…"

"Very nice! I have been working on integrating a PNI micromag 3 axis with ArduImu+. I must admit my set-up is much bulkier.
I am in the process of updating the DCM code to perform yaw-corrections based upon magnetometer input. Part of the code should…"

"For PNI Micromag, there is a trade-off between precision(gain) and update-rate. A good compromise seems to be with "Period select" set to 1024 which leads to 15 msec measurement time per axis => about 50 msec for a 3-axis measurement."
"I have done some testing on an EZstar with a PNI Micromag 3-axis mag. When putting the sensor in the nose, the engine perturbation is hardly noticeable. It is not very good for crashes, but it works. For Quadcopters, i agree it is probably a…"
"Thx Mark for the update. Seems to me like being bound to a paying dev environement is not ideal for a community project like this one. But i will definitely give Labview a closer look!"
"Out of curiosity.
Which dev environment are you guys using for Labview? Is there a free version available?"

"Looks like this project uses a stm32 not an Atmega. These are much faster beasts ;-)"
"Using GPS velocity to infer a reference vector (UAV nose) is not ideal though. In side-wind situations for example. Having a Magnetometer allows to have a cleaner reference vector for attitude correction. Biggest drawback is to account for local…"
"Will,
You are right indeed. When the plane is aligned with the Earth magnetic field, it seems pretty obvious you won't been able to estimate roll...
Having realised this, I believe i could still use the GPS velocity to complement the Magnetic field…"

Hi all,I am wondering if it would be possible to use a magnetometer-only solution to estimate UAV attitude. Indeed, it looks like there are quite good sensors available e.g micromag 3 which would allow to estimate plane attitudes quite accurately…
"No worries. I'll go with sparkfun."
"Any chance you guys will be selling the ardupilot board in your shop? This would save shipping costs for poor european uav addicts ;-)"
