In 2015 The US Marine Academy decided that his graduates returned to the past and learned to navigate using stars. Nine years earlier, he dropped heavenly navigation to his requirements because the GPS was so precise and easy to use.
But recent developments have led to the belief of the academy in GPS. The researchers took the yacht navigation system as it fled to the Mediterranean Sea. New Jersey truck driver charged $ 32,000 for lagging behind a signal that is very close to Newark airport and interference with its system. (Every driver wanted his boss to protect him). Thus, the academy found that his marine officer needed a reserve plan, trusted polaris as their leading star. The sky may never be broken.
Except for clouds. "What are you doing if you can not see the stars?" Says McCain Dimieri, engineer of Lockeit Martin.
He and his team have a solution: quantum sensors.
For almost five years, the DiMario team is a prototype: a cylinder, approximately one foot long and six diameter diameter containing a synthetic diamond cube that rarely exceeds salt crystals. The diamond contains special impurities; When reproducing the cube lattas of carbon atoms, every now and then carbohydrates go and its neighboring nitrogen atom. This so called Nitos vacancy centers, or NV centers, connect with each other in a molecule-like duet inside the diamond and excellent magnetic sensors.
When the green laser diamond shines, the NV Center responds to the red light emitted. Because of the effect of quantum mechanics, the diamond depends on more light on the magnetic field, which is in it. The researchers used diamonds to calculate the magnetic field from squid to neuron firing.
For navigation, DiMario uses a diamond that detects clear ripples and bumps of earth's magnetic field known as magnetic anomalies in the National Oceanic and Atmospheric Association previously mapped. After he defined the anomaly, he can use it as a navigation. At present, ships and planes do not use magnetic anomalies for navigating, since most magnetic sensors measure only the field power and not the direction of the field, says Dimiario. But his team's apparatus can evaluate both. Because it does not require a satellite function, this quantum sensor is less vulnerable to hacking.
So far, Dimaro and his team studied the possibilities of navigating the sensor in flight, the New Jersey Motor Jeep and the Chesapeque Gulf. Finally, DiMario wants to reduce the cylinder size of the hockey puck, where it can be used for any type of transport as an independent check-in GPS.
DiMario and his team are not the only ones to bet on the quantum tracking. The physicist Azur Hansen works in the National Institute of Laboratory of Laboratory Technologies and Technology by Quantum Groscope, which will feel the rotation of the movement. For example, pilots, for example, use gigroscope type to maintain planes and airplanes to navigate. But the current gyroscopes drift, looks like how quickly the clock is even more wrong as time passes. Drift is important that pilots should be given gyroscopes, largely automatic process, every hour or so. Automatic reset works well, except when it breaks. Quantum gyroscopes may be more reliable, as they do not approach all, says Hansen: their fundamental components are atoms and not warp on time.
The Hansen apparatus corresponds to the tablet, the size of the two-sized microframe. Inside the glass, which is less than the sugar cube, eight million Ruby atoms. The laser atoms push the atmosphere to carry more waves than in the basin rather than the discrete particles. The collision arise from a ripple pattern that when imaged, it looks like a bunch of strips. If the Chamber rotates, the stripes will be destroyed. The number of strips shows you the rotation level; And the variations in the sample represent the strength of the Earth's gravitational field. Together with this torque information and earth-level measurement can also be a navigation tool, says Hansen. Like the diamond magnetometer, it can also be used as a GPS reserve system.
The researchers are also observing quantum sensors for other types of measurements. NIST chemist Jay Hendrix developed a pressure sensor that uses the fundamental properties of helium atoms that the aircraft's pilots ultimately use the tall measurement. The sensor works with a laser laser in a glass glass filled with helium gas that changes the laser color from the outside pressure. They used the version of this device to pressure the national standard of pressure that aviation companies use to calibrate all pressure sensors. Boeing and Lockheed Martin have both expressed interest in the device.
However, production issues are important for quantum navigation tools and after the market's preparedness, their ideal goals are still unclear. "They work, but we still need an engineer that they are really difficult," says physicist Paul Kayas in the Sandia National Laboratory. "Just because this quantum does not mean it's better."
Hansen admits that cuts and tune these devices are likely over the years. His group hopes that its gigroscope has been in the market for decades to provide more secure navigation protocols in land, air, sea and space. "I'm not sure the average person will appreciate the quantum-nest," says Hansen. "I do not think they will notice the change."
Even though quantum navigation can not correct the accuracy of the current instruments, you may not need it, just like your tornado canned pastry is not needed than handmade fur. "In the real world, if I can get GPS precision 200 meters away, it would be a huge success," said Diamore Magnatometer. He hopes that along with the commercial version of its equipment, navigational systems of ships and aircraft still use GPS in the first place. Quantum sensors work back, rain or brilliantly.
