NPO Impulse: Ladoga

2019: Representation of a system of a short-wave radio communication Ladoga

On June 28, 2019 the Ruselectronics holding provided to State Corporation Rostec the system of a short-wave radio communication Ladoga which provides uninterrupted information transfer at distance to 3,000 km in the conditions of a heavy interfering situation and also radio-electronic suppression (RAP).

The system developed by NPO Impulse (enters into Ruselectronics), is intended for reliable service of information on communication channels in KV (short-wave) range - 1.6-30 MHz. It provides a stable and uninterrupted relation at a speed up to 19,200 bits/sec. in a difficult interfering situation in the presence of the high level of natural and industrial noise makers and also in conditions of REP due to adaptation in all short-wave range without preliminary sounding. A system automatically distributes a frequency resource between participants of network without operator intervention.

High reliability of a radio communication between remote subscribers in the conditions of noises is implemented by means of continuous reorganization of the transferring and receiving device on group of operating frequencies, optimal for this timepoint.

The foreign systems with pseudorandom reorganization of operating frequency have a progressive tense of synchronization at the beginning of information exchange. In the system of development of NPO Impulse this shortcoming is absent – synchronization happens only once at power supply inclusion then a system automatically supports synchronization in the radio silence mode within 30 days. Thanks to it data transmission begins without delay – right after obtaining the order.

One more advantage of a system in comparison with the analogs which are available in the market is that in it along with transfer of the current information the quality of passing of a signal at alternate frequencies is controlled.

Technical means of the Ladoga system can be placed on stationary, moving, offshore or air objects. A system can be used by bodies of the Ministry of Emergency Situations, the Ministry of Internal Affairs and also any other organizations in situations of failure of the existing communication system and also in the areas which are not equipped with means of communication such as Far North, - told in Ruselectronics. – Besides, a system can be applied to providing with communication marine and river transport, remote meteorological stations, geologists, builders gas - and oil pipelines, railway tracks.
