The US military develops microchips that can navigate without GPS

The microchip developed by the US military has 3 gyroscopes, 3 accelerometers and a master clock. This microchip can replace the GPS system, and will breed a series of small devices that can navigate by themselves. The microchip can be used for small projectiles, allowing them to find targets when GPS is damaged or unusable

Hong Kong time, April 21 , according to foreign media reports, for most of us, GPS (Global Positioning System) has become a part of our daily life, our mobile phones, cars, ships and aircraft rely on satellite networks Find their location. Now, the US military has developed a microchip that is less than 1 cent in size, which can be tracked without expensive satellite networks.

This microchip is equipped with 3 gyroscopes, 3 accelerometers and a master clock, which can accurately lock its position with the help of computer software. The U.S. military research institute, the Defense Advanced Research Projects Agency (hereinafter referred to as DARPA) said: "With these tools, we can track the flow direction and speed of the chip. Because of its small size, this chip can be used in almost any device and will It has a great influence on its weight or shape. "

The size of the microchip developed by the US military is only 10 cubic millimeters, and the size is less than the Lincoln Memorial on the back of the 1 cent coin. It is equipped with 3 gyroscopes and 3 accelerometers, each corresponding to a direction axis, and also equipped with a high-precision master clock. This microchip is of great significance for the development of small drones and robots, as well as projectiles that can self-adjust the flight path. In addition, they can also be used as a "backup" after a fault in a higher-power positioning system. Because of its small size, this microchip can even contain bullets and small missiles.

DARPA project leader Andrey Skell said: "The structural layers and integration packages of microchip sensors are made of silicon materials. This chip is small in size and powerful, and can be dispatched when GPS is temporarily unavailable or restricted. Useful for personal tracking devices, portable navigation equipment, small-diameter projectiles, and small aviation platforms. "
