Rostec has created new high-speed radio modems for drones and robots; they will allow organizing a reliable radio channel between mobile and stationary objects for control and information exchange at a distance of up to 300 kilometers. This was reported in the state corporation itself.
Roselectronics Holding of the Rostec State Corporation has created small-sized radio modems for civilian drones, robotic systems and aviation. They provide high-speed, noise-free radio communication over a distance of up to 300 kilometers and can transmit video in up to 4K format in real time. The devices will be presented for the first time at the Army-2022 forum,” Rostec said in a statement.
Broadband radio modems allow you to organize a reliable radio channel between mobile and stationary objects for control and information exchange. Thanks to this, operators can receive large amounts of data in real time, as well as high-resolution video from UAV surveillance equipment and robotic complexes.
“The new radio modems can operate in the range from 50 MHz to 12 GHz and are characterized by increased noise immunity. Their weight does not exceed 400 g. Thanks to this, the devices can be used in drones and robotic devices with a high-speed data transmission channel, for example, for telemetry of oil and gas facilities, transmission of information from various sensors to control rooms, during topographic surveys or during search and rescue operations, - said Oleg Yevtushenko, Executive Director of Rostec.
The equipment has the function of cognitive radio and uses the method of pseudo-random frequency hopping (PRFC). This allows devices to select the optimal frequencies for operation and avoid interference. As part of Roselectronics, the development is carried out by the Nizhny Novgorod Research and Production Enterprise Polet.
“Radio modems can work with different types of antennas, and the operating frequency range can vary depending on customer requirements. The products implement a number of technologies that provide them with a competitive advantage in the market. In particular, the use of error-correcting coding and technologies based on neural networks allow devices to operate below the noise level, ensuring high reliability of radio communications,” said Aleksey Komyakov, CEO of Polet Research and Production Enterprise.
