I wrote down a napkin sketch of an altitude filter a while back and finally got around to testing it in the simulator. I designed it to improve the sensed altitude of the ardupilot. It is based on a fixed gain observer model and shows very promising results. The idea is to use the "lagless" airspeed sensor to give you a less noisy lagless altitude estimate. Enjoy!

The above picture shows the Project Andromeda ground station circuitry. You can also see the DNT900 from RFM. I believe there has been some interest on this radio in the DIY Drones community and once I finish the construction of the autopilot I will be able to give a recount of my experiences with it. So far, however the radio seems to be extremely capable (especially compared to the…

A quick update on Blimpduino: We've temporarily run out of stock at the DIY Drones store but there are plenty at the Maker Shed, where you can buy them at the same price (it's a very cool store--spend some time there!). We've got some components incoming, and I expect to have them…

We don't talk much about the older commercial autopilots here much, but I was amazed to see the above in my inbox yesterday. The Micropilot 2128g, which is a staple with the university crowd, has only just now upgraded to the 4 Hz uBlox GPS that we in the open source world have been using for years.…

Perhaps it's some sort of cruel joke we're not in on but everything I've been able to find on the Internet about tilt-compensated headings from magnetometers leads to this paper [warning, it's a PDF]: http://www.ssec.honeywell.com/position-sensors/datasheets/sae.pdf…
