Mission Avionics

• Indigenously developed Mission Computers (MC) for Su-30 MKI, Jaguar and MiG 27 upgrade and the prestigious Light Combat Aircraft (LCA).

• Advanced COTS components and technologies have been used in these MCs to provide these aircraft with state-of-the-art computers.

• MC with a performance of over 50 MIPS, hosts ARINC 429 & 1553 B channels.

• Radar Computer (RC) Controls the phased array radar of the Su30-MKI and also functions as the Radar Data Processor.

• Display Processor (DP) Generates anti-aliased computer images to drive four colour Multi Function Displays (MFD), Head Up Display (HUD), Colour and Monochrome Symbol Generators.

• A Core Avionics Computer developed using MC, RC, DP modules and used for the MIG 27 Upgrade.

• Because of its modularity it has been adapted for an identical computer (JMC) for the NAVWASS Jaguar Upgrade.

• Avionics software is developed in a cost-effective PC based networked software development environment with the software development tools and Real Time software platform.

Defensive Avionics

Survivability of military aircraft in the modern combat scenario of sophisticated radar guided air defence weapon systems particularly that of strike aircraft can be enhanced only by equipping them with electronic armor consisting of advanced Electronic Warfare Systems.

• The systems may consist of a combination of Electronic Support (ES), Electronic Attack (EA) and Electronic Protection (EP) systems.

• Development of Versatile Radar Warning Receivers (RWR), Podded jammers and integrated EW suites for military aircrafts.

• The Radar Warning Receiver – Tarang, intercept and identify airborne and ground based acquisition, target tracking and missile guidance radars in multi octave frequency bands.

• The system provides audio and visual warnings in order to alert the pilot to imminent threats.

• The RWR system integrates High Accuracy Direction Finder, Digital RF Memory, Video Processor, Advanced Wide Band Receiver, Microwave Antenna Select Switch, Front End Amplifier etc.

• The integrated EW suite - Tempest, performs the basic functions of threat identification and effective countermeasure action

• Provides man-machine interface in the form of an integrated display/control unit based on Active Colour Matrix LCD Display

• Systems are flight line programmable giving the operational crew enough flexibility to optimize the system configuration.

• Compatibility with on board Multi Mode Radars (MMR), Self Protection Jammer (SPJ) and other avionics through innovative techniques in spectral, temporal and spatial management.

• The system's operational software is based on object-oriented technology and ensures smooth upgrades and reliable performance.

Ground Support Equipment (GSE) • ergonomically designed mission planning stations and mission data loaders • Systems carries out Built-In-Test (BIT) during power-on, periodically during normal

operation without interfering with the system operation and on initiation by the operator.

• Test results, threat activity, system responses and pilot operations are logged into the system with time stamp.

Dare is developing important EW systems such as

• EWSFA (EW Suite for Fighter Aircraft) for LCA and Mig-27

• MAWS (Missile Approach Warning System) for Helicopters and Aircraft

• Self Protection Suite for AEWS (Air-borne Early Warning System) that includes Dual

Color MAWS, RWR/ESM, Laser Warning System and CMDS

Test & Evaluation Facility for Airborne EW System

Range On Wheels (ROW): This facility has been developed for evaluation of installed specifications of airborne EW Systems and for fine tuning electronic attack techniques. This Mobile Range consists of representative threat radar (PRATHIDVANTHI), a reference radar (DRUVA), a Slaved System (DASA), a Data Acquisition Station (SANGAM), a Mission Control Station (SANCHALlKA) and a Generator Vehicle (SHAKTHI).

Range can be used for Avionics, Weapon and EW system test and evaluation. Range is also useful for studying aerodynamic data in real time for aircrafts, helicopters and un-manned vehicles. Range is used by DRDO, Defense Services, HAL and BEL. The range can be offered for civil industry to test their products on requirement basis.

SANGAM, built on a 40 feet trailer, has four independent cabins and a service bay which houses support facilities. The vehicle is fully air-conditioned and has UPS. SANGAM provides laboratory environment and houses data acquisition systems, data analysis facilities, real time telemetry, communication, video recording and displays, central timing and a differential GPS base system. SANCHALIKA is a mission control vehicle, where all the activities of flight trails can be monitored and directed. It has a unique configurable display system, using which effective presentations can be made. This vehicle is fully air-conditioned and has UPS and communications systems. DASA is a slaved pedestal system comprising a servo pedestal, a transmitter antenna, transmitter system, a receive antenna and a receiver system. The servo pedestal is salved to one of the tracking radars. This station will facilitate radiation of programmed threat signals towards the EW aircraft under evaluation and also in the measurement of RF power from the on-board electronic attack systems. SAKTHI vehicle houses a 100 I0JA, 3 phase generator. Power is routed to the vehicle through a distribution system.
