New Alternatives to GPS could Be Jamming- and Spoof-Proof

this yearTwo companies-Sanat Clara, based in California Anilo optical It is based in Montreal Fotonic Silicone Photonik (OSCP)-Own New foot gyroscope–onchip navigation Systems, Allowing An accurate address and follow the distance without satellite signals.

This is amazing Self -deficiency mobility Increasing importance today, because GPS It is vulnerable to Jamming and deceptionWhich can disrupt the movement or provide misleading site data. These problems were well documented in conflict areas, including Ukraine and The Middle EastWhere she faced great military operations GPS to intervene. For dronesWhich depends on GPS to identify, the loss of the signal can be disastrous, which makes them unable to move and sometimes lead to accidents.

optical Gyroscope It has long been seen as a technique that transmits an alternative to the global satellite Navigation systems. Large -sized units such as laser gyroscope It was about Since the 1970s. However, reducing these devices to the size of the chips was much easier than doing it.

Optical gyroscopes produced the beginning In the mid -seventies It has faced difficulties in maintaining the visual signal strength needed to sensitize the exact rotation. Reducing them make the signal ratio to noise worse. Therefore, most accurate electronic devices were followed Reduction The path described by the More Law, the light -based gyroscopes remained huge, and hungry.

If you are driving 100 km, the distance measurement of the system will be accurately 100 meters away, or 0.1 percent of the cut distance. ” –Mario Banchia, Anilo Optical

This was even the case of things CaltechElectrical engineering And professor of medical engineering Ali Hajimiri Its team achieved a breakthrough that overcame the previous restrictions of size and accuracy. in 2018 paperAnd described how they created a small solid status enough to suit the rice. Like optical gyroscopes that appeared before, this gyroscope benefited Sagnac effectThe principle of French physicist for the first time in 1913 George Sagaak.

Sagnac effect occurs when the light beam is divided into two parts and sent in two opposite directions along a circular path. If the device rotates, one beam reaches the detector before the other, allowing the exact measurement of the angle of rotation. Because this method does not depend on external signals, it is fortified Electromagnetic interventionVibration, and Electronic attacks Via an open communication channel – clarify the ideal solution for the applications where GPS is unreliable or completely rejected.

By entering a noise disposal technology, Hajimiri and his colleagues enabled the creation of a light gyroscope. Optical fibers Giroskop and comparable in terms of allergies.

This optical gyroscope is the chip -based pocket -based pocket size of Aneello Photonics is of the same precision as loose versions.Anilo optical

Anello and OSCP enter the market

Less than a decade of hajimiri penetration, ANELLO Photonics and OSCP are now looking to reshape the navigation market through its gyroscope systems. They have made more improvements that allow more miniaturization without reducing the effectiveness of the gyroscope. Low -loss Anilo nitrid Wave Allow the light to spin longer inside the gyroscope, improve signal strength and reduce the accumulation of errors. Anilo techniques suppress other noise sources, so smaller Wave Still lighting is less – and therefore a dim sign – sufficient for precise circulation readings.

The result, he says Mario PeniciaANELLO CEO, was shown on Ces In 2024 and earlier this year. Paniccia explains that his company Self -insufficient measurement units (IMUS), which consists of three gyroscopes dependent on chips and additional ingredients, commensurate with sift From the person’s hand. It provides high accuracy for multiple applications, including agricultureAs self -judgment must maintain the straight grooves for up to 800 meters. He says the longest distances are not a problem with the navigation system. “If you are driving 100 km, the distance of the system will be accurate to 100 meters, or 0.1 percent of the cut distance,” Paniccia says.

OSCP also makes steps in miniature navigation technology. in Ces 2025Oscp founder and CEO Kazim Zandy A multi -promotional embezzler revealed IMU This is half the size of its predecessor. “He is not only smaller, but also more efficient in energy and the lowest cost,” Zandy said at the Las Vegas technology fair. “These gyroscopes can provide a dead account with the site’s accuracy into the centimeters.”

IMUS is designed from Angelo and OCSP to work alongside GPS, and the site’s inputs are constantly monitoring. If GPS intervention is discovered, artificial intelligence (AI) within the system of any of the company automatically converts the movement control to the gyroscope. “If you, for example, in New York,” Paniccia explains, “Jeruscacues indicate that you have traveled 100 meters forward, but GPS says you are now in Texas, Algorithms Learn to control the port to [gyroscope]”

According to Paniccia, the latest ANELLO system is specially designed for uninhabited underwater vehicles and surface cars that operate in the widening of the open ocean, as there are no features to help move. “In the ocean, everything looks as it is,” he says. In the maritime area, where the mobility currents make more complicated than tracking the site on the ground or in the air, Paniccia says that the ANELLO website error is similar to 3 or 4 percent of the cut distance.

Paniccia says a future can be combined with miniature gyroscopes into portable devices FirefightersAllow them to move through smoke filled Buildings Where stairs and abroad are no longer visible. “You will be basically an electronic compass,” he says.
