The Plant "Neptune" was founded in 1944, as the enterprise on the production of dispatch-mine communication equipment. Starting from 1952, the Plant "Neptune" has been the leading enterprise in the field of development and production of special communication equipment.
Nowadays, the plant produces high quality equipment by the modern circuit technology using up-to-date circuit engineering solutions. The output meets the best world analogues and even surpasses it in certain factors. Products are supplied to 14 countries of the world. The equipment is protected with 105 inventions.
One of the main kinds of the plant products is a range of special purpose equipment:
- automated sound ranging complex with increased efficiency of reconnaissance (1B33);
- complex of data transmission devices.
The automated sound ranging complex with increased efficiency of reconnaissance is designed for investigation of enemy's fire positions of artillery weapons and mortars and for the attendance of the own artillery. This complex consists of three base points and one central post placed on the base of the ZIL-131 cross-country vehicle. The complex provides: - definitions of target rectangular coordinates in the determined area of reconnaissance;
- targets ranging fire;
- shooting on a defeat control;
- locating of sound frames for fire transferring on target;
- simultaneous reconnaissance and attendance of the own artillery fire;
- fire attendance of a battery or a battalion.
The complex of data transmission devices consists of the ID - 010 device, fault protection device (AI - 014), signals transformation devices (IA -010, IA - 020), AI - 010 rack, interference removal filters (BLF - 11, DS - 031), AT - 3028M device.
Besides the special equipment, the plant for many years has been producing the equipment for high-voltage electricity transmission lines operation that provides dispatchers service communication, transmission of the data over high-voltage electricity transmission lines condition, connection of line protection devices.
Nowadays, the enterprise produces a complex of VOSP - 480 (optical fibers transmission system, 480 channels) equipment in the construction "Euro-mechanica" - ETSI Standard (ETS 300 119-4) that meets international requirements in the branch of telecommunications.
Products of the plant were repeatedly demonstrated at the international exhibitions and fairs, awarded with 81 medals and 24 prizes. For the high products quality the plant was awarded with international prizes: Paris-25 - International Prize (1997), Brussels - High Quality (1998), Madrid - "Golden Arc of Europe" (1998).
