KRET: Navigation system for drones

2021: Creating a navigation system for drones without GPS and GLONASS

At the end of May 2021, KRET announced the creation of a high-precision navigation system for unmanned aerial vehicles. According to the developers, their technology allows drones to fly autonomously - the coordinates and parameters of the movement of objects are determined even in the absence of ground, sea or space landmarks.

According to the Rostec press service (this state corporation includes the KRET holding), the inertial navigation system, which is the development of KRET, carries out a general geographical orientation and determination of the location of the drone relative to a given trajectory or target, including moving objects. The developers claim that free-form inertial systems are characterized by lower weight and dimensions compared to platform ones, as well as the ability to work under significant overloads.

KRET has developed a navigation system for drones without GPS and GLONASS

According to the head of KRET JSC Nikolai Kolesov, the created navigation system can work using GPS or GLONASS, in combined mode or autonomously. The error of the systems is less than 1% in normal operation and less than 2% in autonomous operation, he said.

It is noted that the system was created on the basis of developments that were previously used mainly in aircraft engineering.

Based on the tremendous experience of creating on-board equipment for airplanes and helicopters, these systems are distinguished by reliability, highest accuracy and versatility. They allow the drone not to depend on ground landmarks and weather conditions, "said Oleg Yevtushenko, executive director of Rostec.

Navigation systems have already been tested on prototypes of Russian drones and have proven their high effectiveness. The technology will begin to be used in 2021. At the same time, it is not reported which drones will receive it as a basis.^[1]
