Abstract

There is disclosed a method of calibrating the output of one or more sensors of an inertial measurement unit, the inertial measurement unit being at least a part of a portable module, the method comprising docking the portable module to a dock; determining that the portable module has been docked; and in response to determining that the portable module has been docked, performing a calibration process to calibrate the output of at least one sensor of the inertial measurement unit.
