1. A method comprising:
- identifying a first vehicle-based direction based, at least in part, on one or more correlation operations that relate to first vehicle-related movement data and at least one of a first acceleration or a second acceleration, said first acceleration and said second acceleration corresponding to one or more accelerations measured using an inertial measurement unit (IMU);
associating said first vehicle-based direction with a first direction that is transformable to an earth-based coordinate frame; and
determining a spatial alignment of the IMU with respect to the earth-based coordinate frame based at least partially on said first direction.

Abstract
The subject matter disclosed herein relates to a system and method for determining a spatial alignment of an inertial measurement unit (IMU). By way of example, a method is described in which a first vehicle-based direction is identified, and the first vehicle-based direction is associated with a first direction that is transformable to an earth-based coordinate frame. A spatial alignment of the IMU is determined based at least partially on the first direction.
