Bharat Electronics Limited is a state-owned aerospace and defense company in India, with around nine factories and many regional offices around the country. They were founded in 1954 in Bangalore, Karnataka, and has its headquarters today in Bengaluru, Karnataka. They are a major company who specialize in all sorts of military equipment from various sectors and uses. In this article, we will focus on one of them.
Defense Communication Products
Regarding communication devices used on the battlefields and in bases, BEL produces dozens of different products, and we will explore several sections.
1. Radios, Base Stations, Repeaters
Medium Power HF SSB Manpack Radio (LHP 265DI)
This advanced device provides a complete solution for all short range communication needs among the HF brand. It gives you voice data, telegraphy, and flash messaging. The radio is compatible with different antennas. It meets JSS 55555 L3/N3 specifications. The features of the device include:
DSP Based Tactical HF Radio, 100 preset channels, selectable digital squelch, selective calling, dual frequency operation, compact, lightweight and modular construction, built-in options, best call (FAST ALE), vocoder based Digital encryption, secure high-speed data modem up to 4800 bps, frequency hopping.
2. Satcom Solutions: S/C/ Extended C/KU Band
Satcom Messaging Terminal
This is a compact hand-held communication system, which provides secure location reporting, short messaging, navigation, and distress communication. It can be deployed in under a minute, making it perfect for defense forces. Its features include:
Secure data transfer, built-in security, separate AC/DC adaptors, built-in GPS, alphanumerical 3×6 keypad, and a 2.8” display.
C-Band Earth Station Antenna (ESA)
This 11-meter antenna is used for satellite communication operation all around the world. It uses multi-piece stretch-formed panels, which are mounted on the elevation-over-azimuth positioner. This device has no troubles in windy conditions, as it is a high-performance solution, meeting ITU requirements. It can be paired with most fixed structures. The features of this station antenna include:
High performance, low side lobes, precise surface, high stiffness, low cross polarization, and aluminum multi-panel construction.
Transportable Satellite Terminal (TST)
The motorized auto tracking sitcom terminal is primarily made for vehicle-adapted application and use. As such, it is highly mobile and therefore presents a wide variety of situations where it is useful. The most important features are:
Secure data, voice and video communication, MFTDMA satellite access technology, single vehicle configuration, 1.8m/2.4m dish type antenna, on the pause communication, tail/road transportable, mesh/star/hybrid network topology, and redundancy of critical subsystems for a critical mission application.
3. Radio Relays (FH, HC)
Point to Multi-Point Radio
This radio can either work as a base station or a remote station. The former is capable of communicating with up to six remote stations, as it uses the beam-switching antenna. The latter uses the parabolic reflector antenna for reliable service. It also offers both the Indoor and Outdoor units. The features of this radio include:
Multiple access, FEC scheme for an error-free transmission, full duplex communication, IPV4 user interface, built-in crypto and FH, redundancy at the base, auto frequency evasion, automatic power control, and auto beam learning.
4. Tank Communication Radios (CNR)
Tank Intercom System (R 174 – MK II)
This tank communication system is designed for the communication between tank crew members, as well as between crews of different tanks, all through radio technology. It is compatible with Radio Sets R-173, CNR, STARS-V and TADIRAN. Its features are:
Internal two-way communication between six users at the most, external two-way communication, listening to ring tone from radio, internal circular two-way communication between all users, ringing external user over the radio, the special audio tone for laser warning signals, and facility for selecting and controlling audio leaks.
5. Strategic Communication
Digital Mobile Radio Relay (DMRR)
This multi-layer communication system provides last mile connectivity over radio/fiber link/sitcom, using NLDSP point of presence. This is an integrated, shelterized, and quick to deploy mobile communication system on wheels. The features include:
IP based Network for voice and data, hydraulic stabilization on the all-terrain vehicle, self-sufficient power system, centralized network management system, intrusion prevention system, and data security with IP Bulk encryption.
