What is Positioning, Navigation and Timing (PNT)? Navigation, the ability to determine current and desired position (relative or absolute) and apply corrections to course, orientation, and speed to attain a desired position anywhere around the world, from sub-surface to surface and from surface to space; and.
Quantum navigation operates via a process called atom interferometry. If you cool atoms to just millionths of a degree above absolute zero, then hit them with beams of light, you can trick them into a quantum superposition. Each atom takes on two states simultaneously: moving and still.
What is quantum positioning?
A quantum positioning system (QPS) is proposed that can provide a user with all four of his space-time coordinates. 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.
Navigation is also a familiar concept, which allows for the calculation of a route from position A to position B. Finally, Timing ties the two elements together, allowing one to determine the duration of travel along a route as well as the accurate local time in any number of locations on the globe.

What is space PNT?
SpacePNT is an innovative, low cost GNSS receiver maker for the fast-growing New Space satellite market, delivering decimetre-level positioning accuracy for single satellites and LEO constellations and highest signal reception sensitivity for Moon missions, all in real-time through its unique Positioning, Navigation …
How is quantum mechanics used in GPS?
For example, a GPS sensor determines its location by using the amount of time it takes to receive a signal from a satellite. The work involves transferring information from electrons to photons, then using quantum entanglement to increase the photons’ sensing capabilities.
How does a quantum compass work?
A quantum compass contains clouds of atoms frozen using lasers. By measuring the movement of these frozen particles over precise periods of time the motion of the device can be calculated.
What is a quantum accelerometer?
A quantum accelerometer uses atom interferometry to measure accelerations along a horizontal axis. A phase locked SolsTiS system underpins this setup and provides the extremely low phase noise required to make high sensitivity measurements and dynamic frequency tunability to address multiple atomic transitions.
What is satellite PNT?
Satellite Positioning, Navigation and Timing Service (PNT)
Why is PNT important?
Positioning Navigation and Timing. Positioning, Navigation, and Timing (PNT) is necessary for the functioning of the Nation’s critical infrastructure. Whether for civil, commercial, or military use, nearly all sectors rely on accurate PNT information to provide services.
