The «Ruselectronics» holding, part of the «Rostec» State Corporation, presented the new «Lemma» satellite radio station at the «Army-2024» forum. This device, designed for installation on mobile objects, provides reliable communication on the move and has no domestic analogues. The «Lemma» radio station can become indispensable in emergency rescue operations, as well as operational search and special events.
One of the key features of «Lemma» is the use of a phased antenna array (PAA), which made the device compact: the height of the antenna unit is only 20 cm. The radio station can be installed on the roof of any vehicle, including cars, using standard railings. To protect against wind loads that occur during movement, the device is equipped with a radio-transparent fairing.
The antenna module of the radio station is capable of automatically pointing at the satellite and tracking its signal, ensuring stable communication on the move. In addition, a manual antenna guidance mode is provided. The radio station operates in the C and X bands, supporting interaction with spacecraft such as «Yamal» and «Express-AM».
An experienced sample of the station was presented at the forum, fully developed without the use of imported components. The development of this satellite radio station was carried out by engineers of NPP «Radiosvyaz», and all key components, including the PAA, were created by specialists of the enterprise.
The General Director of NPP «Radiosvyaz», Rinat Galeev, noted that the unique feature of «Lemma» is its ability to provide communication on the move, continuously keeping the antenna directed at the satellite. This device is especially useful for transmitting data and coordinates in remote areas where there is no telecommunications infrastructure.
