1. A system for small space positioning comprising:
- a transmitting device, movable within an approximate range, configured for transmitting a modulated continuous wave, wherein the modulated continuous wave is an ultrasound wave and wherein the modulated continuous wave includes a carrier signal and a base-band signal; and
a receiving unit configured for receiving signal(s) transmitted by the transmitting device and for determining a position of the transmitting device within the approximate range based on analysis of both the carrier signal and the base-band signal received from the transmitting device wherein the analysis of the base-band signal provides determining a position with accuracy in the order of magnitude of a wavelength of the carrier signal and analysis of the carrier signal provides improving accuracy of the position within the determined wavelength.
