The KRET holding company of the Rostec State Corporation will supply unique platform-free inertial navigation systems for domestic unmanned aerial vehicles. The advantage of the development is high accuracy and the possibility of autonomous operation. The system can determine the coordinates and parameters of the movement of objects even in the absence of land, sea or space landmarks.
For use in domestic drones, developments that were previously used mainly in aircraft construction were adapted.
Navigation systems provide the definition, complex processing and transmission of flight and navigation data. At the same time, inertial and satellite information is transmitted simultaneously via separate channels.
"Our developments in the field of creating inertial navigation systems can be called unique. Based on the vast experience of creating on-board equipment for airplanes and helicopters, these systems are characterized by reliability, the highest accuracy and versatility. They allow the drone to not depend on ground landmarks and weather conditions, " said Oleg Yevtushenko, Executive Director of Rostec, as quoted by the press service of the corporation.
The inertial navigation system provides general geographical orientation and determines the location of the UAV relative to a given trajectory or target, including moving objects.
Free-form inertial systems are favourably distinguished by their lower weight and dimensions compared to platform systems, as well as the ability to operate under significant overloads.
"In navigation systems, it is possible to work on GPS or GLONASS, in combined mode or independently. At the same time, the error of the systems is less than 1% in normal operation and less than 2% in autonomous operation, "said KRET CEO Nikolay Kolesov.
In 2020, these navigation systems were tested on prototypes of Russian drones and proved their high efficiency. The first samples of the latest navigation systems will be delivered for use on Russian drones in 2021.
