1. A localization apparatus, comprising:
a time of flight circuit configured to emit a first modulated light signal and to receive reflections of the first modulated light signal from at least three devices;
a processing circuit configured to determine, based on the first modulated light signal and the reflections, positions of the at least three devices in a first coordinate system associated with the localization apparatus; and
a receiver circuit configured to receive second modulated signals from the at least three devices, the second modulated signals comprising data indicating positions of the at least three devices in a second coordinate system,
wherein the processing circuit is further configured to determine a position and an orientation of the localization apparatus in the second coordinate system based on the positions of the at least three devices in the first coordinate system and the data indicating the positions of the at least three devices in the second coordinate system.
