Space exploration has a great meaning for mankind. There are
\nmany space technologies that have been explored for space, but then
\ntransformed for human everyday use. One of such technologies is
\nGPS navigation.

Quantum Positioning System

Thomas B. Bahder · ArXiv.org · 2004

A quantum positioning system (QPS) is proposed that can provide a user with all four of his space-time coordinates. The user must carry a corner cube reflector, a good clock, and have a two-way classical channel of communication with the origin of the reference frame. Four pairs of entangled photons (biphotons) are sent through four interferometers: three interferometers are used to determine the user's spatial position, and an additional interferometer is used to synchronize the user's clock to coordinate time in the reference frame. The spatial positioning part of the QPS is similar to a classical time-of-arrival (TOA) system, however, a classical TOA system (such as GPS) must have synchronized clocks that keep coordinate time and therefore the clocks must have long-term stability, whereas in the QPS only a photon coincidence counter is needed and the clocks need only have short-term stability. Several scenarios are considered for a QPS: one is a terrestrial system and another is a space-based-system composed of low-Earth orbit (LEO) satellites. Calculations indicate that for a space-based system, neglecting atmospheric effects, a position accuracy below the 1 cm-level is possible for much of the region near the Earth. The QPS may be used as a primary system to define a global 4-dimensional reference frame.

Indoor Positioning System

Rabia Tariq, Sana Latif, Wajiha Haq · 2012

Indoor positioning System-The most reliable positioning System in the world to find the position of an object in an Indoor environment where Global Positioning System does not work.INDOOR POSITIONING SYSTEM is a system in ‎which we can locate the position of an object in an ‎indoor environment utilizing ultrasonic waves ‎generated by narrow directional ultrasonic ‎transmitter. To achieve the objective of position ‎detection, we have designed ultrasonic transmitter ‎and receiver circuits, RF transmitter, and receiver ‎for synchronization purposes. By implementing ‎time of arrival method, we have located the ‎position of an object. It is accomplished by using ‎distances between the multiple receivers and a ‎single transmitter located in a room. RF signal ‎starts the timer and when ultrasonic waves will ‎reach at the receiver end, it will stop the timer and ‎then the extracted signal from the receiver is ‎transmitted to the microcontroller for locating ‎position of an object. The systems using ultrasonic ‎waves have the advantage that it can be built on ‎low cost and has relatively high accuracy to detect ‎the position of an object in an indoor environment.‎
