> I learned that real world IMU use in navigation is pretty ugly and has to be supplemented due to constant errors. This can be particularly difficult when flying. In my case I used other sensors, such as a GPS. But a strictly IMU-only approach to lengthy navigation is, AFAIK, impossible.
Yeah IMU error can be annoying unless you shell out $$$, but this issue occurs with many other kinds of sensors as well.
One common trick is to treat the IMU error as another state variable that is evolving over time. It won't eradicate the compounding error, but it will reduce the amount of calibration necessary.
