Claim 17:
18. A system comprising:
a first inertial measurement unit
a second inertial measurement unit fixed relative to the first inertial measurement unit;
one or more processors; and
memory storing instructions executable by the one or more processors to cause the vehicle to perform acts comprising:
receiving, from a first inertial measurement unit coupled to a system, a first rotational velocity information;
calibrating, based at least in part on the first rotational velocity information and using a first technique, the first inertial measurement unit relative to the system;
receiving, from a second inertial measurement unit fixed relative to the first inertial measurement unit, a second rotational velocity information; and
calibrating, using a second technique that determines a relative rotation of the second inertial measurement unit relative to the first inertial measurement unit, the second inertial measurement unit relative to the reference.
