I had a chance this week to fly a MIDG-II in my university's Sig Rascal
110. The MIDG-II is a combination gps/ins/imu type deal that outputs
both position (gps) as well as gyro/acclerometer based attitude (roll,
pitch, yaw.) It can also output magnetometer readings as well as
velocities and raw accelerations. It's a neat toy for doing UAV type
stuff: http://www.microboticsinc.com/midg.html
We connected the serial output of the MIDG via a radio modem link to a
laptop on the ground which let us monitor the flight in real time and
captured the binary data stream.
Today I whipped up a little program to load and parse the binary data
and feed it into FlightGear
The MIDG dumps out position at 5 hz, and attitude at 50hz. This is more
than enough to capture a lot of the subtle nuances of the real flight
... dutch rolls, aileron rolls, loops, slips, jittery thumbs, wind
gusts, etc. can all be seen in the resulting replay.
I might be the only one here who's had a chance to play around with one
of these, but if anyone else has one or has something similar, it's kind
of neat to pump the data into flightgear and watch the flight from
inside a virtual cockpit, or from a chase view.
Curt.
