The Scan Mirror Test system is used for validating the linearity of the Scan Mirror Mechanism that is deployed on-board satellites. The system was a custom turnkey project in the electro optics domain. Scan Mirror is swept linearly by a mechanical scanning gimbal and this allows the optical sensor to take large field exposures of the target using a single dimensional array sensor on-board the satellite. The linear mechanical movement is important for achieving an imaging linearity of the satellite, utilizing a complete non contact electro optic technique. The test system utilizes a thermovac compatible 22Mpixel camera and a pulsed laser source to monitor the movement of the scan mirror and thereby compute the movements linearity. Micro radiant level resolution is achieved through pixel level estimation algorithms.

Data Patterns has developed the required expertise to design and maufacture BLDC Motor drivers used in close loop position control applications primarily for actuator control and Thrust vector nozzles and control surface (FINS) for missile and Torpedo applications. Multiaxis gimbals are developed for specific requirements. These products are supported by test systems for electro Hydraulic and Electro mechanical actuator testing

The Digital Flight Control Computer is a Quadruple Redundant Flight Control Computer designed by DRDO and ADE and manufactured by Bharat Electronics Limited. Data Patterns has designed and manufactured the Automated Test Equipment required for the validation of this DFCC. Segregated into an Analog Test System and Digital Test System, relevant boards can be plugged in on the front of the ATE and tested for full functional performance. Specialised adaptors enable probing of the backplane signals and also carry out measurements on the board by manual probing for debugging requirements.

Data Patterns utilizes Fibre Optic Communication for high speed data transfer requirements. Protocols such as Serial FPDP, Aurora, PCI Express, Gigabit Ethernet are implemented on Fibre Optic Medium. Solutions using DWDM and EDFA components for high density fiber optic communications solutions are implemented

Based on order from the Navy, Data Patterns developed the complete Automated Test Equipment required for validating all the Line Replaceable Units (LRUs) utilized in the Seaking Helicopter. The upgrade was carried out at multiple Naval bases in India. This engineering effort was fully validated and approved by the Quality Control Agencies for testing the flight critical LRUs and functioning of the LRUs on the aircraft. Data Patterns is one of the few companies in the world who has carried out the implementation of a full aircraft LRU Test system.

The FPGA Mezzanine Card is used by Data Patterns to implement signal interface with external world compatible FPGAs mounted on the FMC carrier there are primarily used for high speed analog interface for digitization (ADCs) and waveform generation (DACs). This form factor is also utilized for special IO Interfaces such as various avionic protocols and buses. FMC IO signals may be routed via front panel connectors or through Mezzanine connectors that route the signal back to the carrier board for routing through rear IO of the Chassis. The system interface is designed for routing to FPGAs using a VITA 57 0.05 Pitch Terminal Array Assembly. Signal Conditioner Card (SC) Data Patterns utilize a custom form factor connector suitable for use as a plugin modules on carriers in cPCI, VME or VPX standards specially designed for slow speed precision signals. Switched Mezzanine Card (XMC) XMC switched Mezzanine Card form factor is used for providing cross-platform functional solutions usable on cPCI, VME and VPX systems, primarily focused on PCI Express based interface. The XMC is derived from the PMC form factor. A very broad range of IO functionality is provided through XMC modules.

Data Patterns has designed and manufactured Fibre Optic Gyro based Inertial measurement units for under water applications with all algorithms including Kalmann filters and co-ordinate transformations implemented.

VXI stands for VME eXtensions for Instrumentation. It is an open standard first developed by five leading Test and Measurement companies in 1987 to standardise a backplane capable of developing open, interchangeable instrument modules that could be used to build Automatic Test Equipment (ATE). Data Patterns designs and markets a wide range of VXI modules, some of which are listed below. Due to the use of the latest technologies, Data Patterns VXI modules offer the highest IO density available in the industry today. Further enhancements of functional capabilities are achieved by the use of VXI IP carriers and VXI M Module carriers. This extends standard functions available from Data Patterns in these mezzanine architectures to the VXI platform. Data Patterns' VXI modules are utilized in high reliability applications such as Count Down Checkout System for the First and Second Launch Pads at Satish Dhawan Space Centre SHAR operated by Indian Space Research Organisation (ISRO)

These products are implemented through modern high speed digitizers and digital to analog converters and are backed by FPGA based processing that implements baseband tuning and high speed I&Q vector generation algorithms. These find application in real-time signal processing, electronic waveform generation, digital tuners, and communication products.

Data Patterns has developed a line up of State of the Art Integrated solutions for spectrum monitoring, wideband searching, ECM & ESM, direction finding for Airborne and Ground Mobile Applications standard Products include VHFUHF Search Receiver, HF Search Receiver, Monitoring Receiver & Jammers.

• The INTU system consists ofProcessor module,INTU Interface Module,Light-up module

Instrument Test Unit For Advanced Inertial Sensors (INTU) is used for testing and evaluation of Ring Laser Gyro (used in GSLVPSLV launch vehicles), that detects the angular displacement during rotation. The INTU receives displacement signals from the sensor (RLG) to evaluate the sensor characteristics and also generates signals required towards initiating the action of the sensor. This system contributes to the successful launch of many of India's rocket launch vehicles including the Polar and Geostationary Satellite Launches, the Chandrayan and the Mars Orbiter missions.
