Global positioning systems (GPS) have become ubiquitous in everything from phones to cars.
Also, GPS is easily jammed.
Thus, if the applications cannot tolerate the risk of GPS unavailability, an alternative is required."

Working With Uncertainty
Schwindt and his colleagues recently described the quantum devicein a paperpublished inAVS Quantum Science.
The vacuum package would go into an atom interferometer, accelerometer, or gyroscope.
Three high-precision accelerometers and three gyroscopes form an inertial measurement unit, which measures tiny changes in direction.

There are two main ways of navigating without GPS, Schwindt said.
One way users could benefit from alternatives to GPS is enhanced security, cybersecurity expertMagda Chellytold Lifewire.
“We are seeing thousands of mobile applications providing services based on GPS coordinates.
Even if you are using GPS, there are ways to improve the experience.
“Common causes include GPS jamming, spoofing or signal errors in urban canyons.”
