"It isn't entirely hardware independent, but it is flexible. You must have a GPS, accelerometer, and gyro. You should almost certainly also have a vector observer in the form of a magnetometer and/or thermopile. Without the vector observer, the…"
"Right now, I'm working on a journal article. If that gets accepted, then I'll be able to publish a preprint. But I think it would inappropriate to self-publish the journal paper before it goes through peer review."
I've been writing a GPS-INS integration EKF for my Master's research. This may be the first implementation of this algorithm to be published as Open Source software and you can find it on bitbucket. See also some discussion on the OpenPilot forums.
"It has relatively poor initial bias stability. The turn-on bias is +/- 20 deg/s, with an additional 20 deg/s swing over the temperature range, according to the datasheet. It's possible that they got those terms mixed up, and all of the initial bias…"
"Option 1) Use the telemetry link between the GCS and the vehicle to provide commands using some kind of native PC digitial interface. Depend utterly on your wireless modem for all control, whether that modem is an XBee, or a 900 MHz modem, WiFi or…"
What happens to a MEMS gyro's null point if it starts up while actively rotating? Does the internal hardware make any assumption about the initial motion of the sensor when it starts up?Say the gyro is sitting on a 50 deg/s spinning turntable when…
"1. As soft as you can get without sacrificing basic structural soundness.
2. For these sensors, it almost doesn't matter with respect to vibration. You don't want to propagate any engine vibration into the sensor chassis at all if you can avoid it.…"

Based on the sample data provided by Loris I have written some code to produce an Allan Variance plot of the data. The program source code is ISO C++98, and should compile with any standards-compliant compiler. G++ 4.4 tested, I expect MSVC 2k8 or…
I'm developing a Kalman filter-based GPS/INS integration system, and I'm worried about one of my core assumptions in testing. I've been assuming that the u-blox 5 GPS produces a 4 Hz true fix (v5.0 firmware), with one-sigma RMS position error of 10…
