1. An unmanned aerial vehicle (UAV) comprising:
a satellite positioning system receiver;
an inertial measurement unit having an associated accelerometer; and
one or more processors configured by executable instruction to perform operations comprising:
determining a first acceleration of the UAV based at least on information from the accelerometer received at least one of prior to or during takeoff;
determining a second acceleration of the UAV based at least on location information received via the satellite positioning system receiver at least one of prior to or during takeoff;
determining a relative heading of the UAV based at least in part on the first acceleration and the second acceleration; and
directing the UAV to navigate an environment based at least on the relative heading.
