1. A computer-implemented method for spatial tracking using a hybrid signal, comprising:
receiving, from a peripheral unit and via an antenna array of a central unit, a signal that includes:
inertial measurement data from an inertial measurement unit (IMU) of the peripheral unit; and
a constant tone extension (CTE);
determining, based on the CTE, direction data for the peripheral unit; and
determining, based on the direction data and the inertial measurement data, spatial tracking data for the peripheral unit in response to a disruption in an optical tracking associated with the peripheral unit.
