"Kuantum Accelerometer" Tracks Location without GPS

GPS technology is so present now that it's hard to remember the day when you can not just pull out your phone and find out exactly where you are in the world. However, it is actually recently developed and one that could be rejected in the future. GPS relies on a satellite network that could be damaged, blocked or destroyed. You can also not get a good GPS conclusion when you are underground or around high buildings. However, there may be an alternative. Imperial College London and the engineering firm M Skuared have developed a new "quantum accelerometer" that can provide precise locations without any external system.

Navigation with accelerometer was possible and it took some time. Your phone is an accelerometer that monitors movement and orientation. However, it is not practical to use this navigation technology to a great extent. The accelerometer measures the movement, so you can use it to find out where you are, if you have a good reference point. Microsoft has released an internal navigation application Put the guide on Android a few years ago it works. The problem is that the accelerometers are not perfect – they lose one inch and there, and these errors connect over time until you know where you are.

Quantum accelerometer from the Imperial College in London could solve this problem because it is greatly accurate. While the device is nominally portable, it's not very compact or easy to use. Quantum mechanics tells us that all matter has wave property, but it is very difficult to observe in everyday life. Ultra-cool atoms show their wave characteristics more, and this is the key to a quantum accelerometer.

Imperial College London uses a powerful laser system from M Skuared to cool the cloud of atoms at very low temperatures until the visible wave is visible. As the atoms fall through the accelerometer chamber, the property of the wave is under the influence of motion. The researchers used a laser interferometer to monitor perturbations in quantum waves, enabling the system to track motion with high precision.

S0, the accelerometer knows when moving with a high degree of accuracy, and therefore knows where it is at all times based on where it started. Currently, the system measures the movement on one axis, but it should be possible to scale the design by measuring all three axes and three rotation directions for complete navigation.

The team says the device now exists on ships or trains for navigation without access to GPS. However, for now it's too big to fit into your phone. Lasers just exaggerate it. You may one day have your own quantum accelerometer in your pocket, but not soon.
