  1. Avionics System Design. Also Avionics Upgrade System design.

 

Avionics System Design:

 The complex modern avionics system plays an important role in increasing the effectiveness of a flying machine to achieve its mission. The Avionics system is designed to meet the mission requirement under the given operating environment and constraints. The design involves the hardware architecture, selection of suitable sensors, cockpit displays, controls, switches, mission computer, software architecture and Software Requirement Specification (SRS) generation. Also involves, error budgeting of sub systems, sensitivity analysis and algorithm development.

 

Avionics Upgrade System design:

 All the services mentioned under the Avionics System Design can be extended for Avionics Upgrade of existing aircrafts.
  1. Fixed base Flight Simulator and MMI/Pilot Vehicle Interface (PVI) evaluation Tool

 

A full size cockpit with functional displays and controls are driven through a real time simulation system. This will have a 3 window outside imagery visual either projected on a screen or reflected through collimating mirrors. This will be a tool for evaluating the Pilot Vehicle Interface (PVI) for an aircraft under development or upgrade, and for training the pilot and the maintenance crew.

 
  1. Navigation systems (Inertial sensors based or GPS or combination of both) for land vehicles or aircrafts

 

Navigation systems are built with suitable sensors to provide, position information, guidance to destination, interfacing with moving map displays or DMG (digital map generators) with displays, repeater units for the driver in case of tanks. These systems are custom built by developing the software.

 

 

  1. Telemetry Systems

 

Total solutions provided for telemetry including supply and integration of Bit Synchronizers, Frame and Sub Frame Synchronizers, Simulators, Analog to Digital Multiplexers, Intelligent Digital to Analog converters and Communication controllers.  Powerful software available from the Park portfolio of products meeting all the stringent needs of the application makes the total system at par with any system available internationally.
  1. Man-Machine-Interface (MMI) design

 

This is applicable to many systems, where a man is, using a complex system, performing a critical operation especially in defense applications. A rapid prototyping or a simulated facility is used for this, which can be configured for different applications and various critical and emergency conditions. The design will encompass ergonomics, logical grouping of controls/displays, workload measurement, ambient condition effects and percentile assessment.

  1. Algorithm development for weapon aiming

 

Algorithms for weapon aiming calculations are developed and verified using real time software simulators. This will include the dispersion of the inputs and the system errors for finding the CEP of the target hit.

 

  1. Fire Control Systems for Tank Guns

 

The gun mounted on the turret having degrees of freedom 360 in azimuth and about + 60 to – 20 in elevation attains an effective capability to aim and hit the target even while moving over a rough terrain. This is achievable by a suitable Fire Control System, which would stabilize the gun towards the target irrespective of the movement of the tank. The system takes positional, velocity and attitude information along with attitude rates to stabilize the gun towards the target. A computer performs the complex algorithm to calculate the drive input to the turret and barrel motors.

 
  1. Development of Automatic Test Equipment (ATE) and Developing test programs for ATE

 

Large number of complex systems and their electronic modules are to be tested for the serviceability and diagnostics for repair in depots of the defense services. The turn around time is of paramount importance. This is achieved through intelligent Automatic Test Equipments. The systems under tests are complex in nature having intelligent microprocessors and the electronic modules are of highly dense digital, analog or hybrid boards requiring multipurpose ATE. The ATE’s are built to cater the testing and diagnostic needs of these complex boards.

 

For developing the Test Programs a thorough knowledge of the system/module under test and the ATE itself. The test coverage should be 100 %, at the same time keeping the test pattern generation to reasonable size with guided probing into the board. ATE test programs are developed using a simulator in case of digital boards and tuned to match the actual hardware board. Suitable signature analysis is incorporated to make the diagnosis faster to find the fault and

 rectify.
  1. Development of Special Purpose Test equipment

 

The modern defense services use very complex, intelligent computer based systems. Though the supplier provides specially designed test equipment along with the system, soon the test equipment becomes unserviceable due to lack of spares and obsolescence. Hence, the Special Purpose Test Equipments are designed using standard PC with PC bus compatible add-on cards. Special interface requirements are met with FPGA and EPLD. This approach greatly reduces obsolescence and spares problems.

 

  1. Antenna control system for tracking fast moving targets like, missiles, rockets, aircraft etc.

 

A suitable drive unit with precision tracking control system for positioning the radar antenna in azimuth and elevation has been designed for fast moving targets like missiles, rockets, aircrafts, etc. for an angular velocity and acceleration of 28 degrees/sec and 28 degrees/sec/sec. The data collected from different subsystems are recorded and presented in real time in a user friendly GUI.
