Roselectronics: Noise-proof equipment for control of robotic equipment

2023: Introduction of interference-proof equipment to control robotic equipment

The Roselectronics holding of Rostec State Corporation has demonstrated interference-proof equipment for controlling robotic equipment, in particular unmanned aerial vehicles. The solution is able to integrate into self-organizing wireless mesh networks that form an autonomous information space. This allows you to transfer data in real time without the Internet and binding to cellular networks at a distance of up to 5 km. The equipment is part of the software and hardware complex for monitoring the ice situation in the water area of ​ ​ the Northern Sea Route. Rostec announced this on June 22, 2023.

The system consists of a radio modem, amplifier and antenna, which are mounted on the drone. All devices are small in size, for example, the dimensions of the modem are only 130x75x30 mm. The equipment can operate in a wide frequency range, from 500 MHz to 3500 MHz, and also withstands the harsh northern climate.

Russia has been increasing its presence in the Arctic from year to year. This is a strategically important territory for us both in terms of natural resources and in terms of the defense of the northern borders of Russia. The stability of equipment in this region should be maximum. One of the solutions that Roselectronics presents helps protect drones from interference. For this, the technology of pseudo-random tuning of the operating frequency is used. The method allows you to use one or different frequencies for control and data transmission. Thanks to this, the control of the drone remains stable, even if it completely refuses interference at one of the operating frequencies, "said Oleg Yevtushenko, executive director of Rostec.

As part of the hardware and software complex, the equipment is responsible for transmitting commands from the operator to the drone and receiving information about the ice situation from a special radar station. To transmit commands in the modem, noise-proof low-speed communication channels are used - up to 200-300 Kb/s. To broadcast live streaming video and send telemetry data, the device uses high-speed channels that support speeds up to 25 Mbps.

The equipment was developed within the framework of scientific and technical cooperation of PJSC Intelltech"" VNII "Vega" and (included in Roselectronics).

The equipment is a radio-protected universal means of communication and control of unmanned aerial vehicles. At the same time, the equipment is intended not only for use as part of robotic complexes and UAVs, it can also be used in telecommunications, navigation and remote sensing of the Earth. As of June 2023, the decision is being tested as part of the Aeromobile Pilot cyber physics platform, designed to monitor the water area of ​ ​ the Northern Sea Route. Our company is ready to start mass production of equipment, - said Mikhail Vinokur, General Director of Inteltech PJSC.
