That was you and Andrew Paul, and as I recall, you were the only person
who exchanged e-mail with him. He was at a university on the east coast,
wasn't he? Or something like that?

I've just re-read his code (INS.c) and the short paper he wrote
describing it (numerical.pdf), and I'm not sure we can do better than
recommending that they read that paper. Given only an IMU, Andrew Paul's
derivations based on Simpson's rule are as good as anything else I can
think of, and his paper explains them pretty clearly.
