First Israel Multinational BMD Conference Directorate of Missiles, DRDO, India Site selection for Sensor deployment Identification of site is very important step towards planning for Test Range. This factor plays a very critical role in Range budget calculation. Site should be chosen in such a way that instrument deployed at the specified location could cover the maximum possible range of Missile flight and provide the desired data & information to the designer. All instruments like Radar, EOTS, Telemetry Station, and High speed Camera has to be positioned accordingly. Range Network May 06, 2010
First Israel Multinational BMD Conference Directorate of Missiles, DRDO, India Electro Optical Tracking System Concept of line-of-sight tracking and Real-Time image processing, enables the system to provide the precise trajectory information of the target right from take-off till the imaging limit in Infrared Band (3 -5 micro/8 -13 micr). Object detected by EOTS Electro Optical Tracking System • • IR imaging camera. It detects the object within a rectangular marked region sometimes called as gate, locks-on and tracks the detected object. The system tracks the object by the principles of real time image processing. reference point of boresight (central sensor axis). These angular deviations termed as error signal for the closed loop control. The closed loop control in order corrects the pedestal movement in each video field/frame to maintain the object in the center of the field of view (FOV). May 06, 2010
First Israel Multinational BMD Conference Directorate of Missiles, DRDO, India Radar Systems Radar System Radar system is capable to measure, Slant Range, Radial Velocity, Azimuth & Elevation angles in real time. Range Radar aims at providing real time location’s information for all sorts of flight trials. May 06, 2010
First Israel Multinational BMD Conference Directorate of Missiles, DRDO, India Telemetry Systems Telemetry plays a crucial role during any test launch campaign Phase III: This phase includes Sensor checks, Telemetry Encoder, Transmitter & Ground System Compatibility Checks. Phase IV: This Phase covers Integrated System Health Checks, Range Integration Checks Real Time Launch: During real time, telemetry accomplishes Tracking, Data acquisition, Storage, De-commutation, Processing, Distribution and Display.

First Israel Multinational BMD Conference Directorate of Missiles, DRDO, India Range Integration Checks Once Test planning is done, all the instruments, sensors and experts are in place, then Range integration check is done. A count down document is prepared and all the events as per the document is exercised. This exercise consists the events of Missile launch and the Test Range role. Each person and machine is geared up for the final test flight once this test is successfully completed. Mission Activities • Post Mission Activities • After the flight test is completed, post flight analysis has to be done to examine the data collected from the various tracking stations and reaching at a proper conclusion. • All the data related to the test and evaluation is handed over to the designer for their further perusal and analysis, which helps the designer to incorporate necessary modifications in the design.
