Some systems have been supplied to M/s. Bharat Electronics Limited. Some Oceonographic systems have been supplied for scientific research purposes.

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

Power supplies of various ratings for Air, Naval ground based and space applications are developed. Products are implemented in VPX, VME, cPCI and custom form factor designs.
Most products qualified to requirements of MIL-STD-461C and MIL-STD-810D or the equivalent JSS 55555 are designed and manufactured. Airborne versions are designed to meet MIL-STD-704D. Specific design constraints are handled with respect to long time storage life and suitability for air cooled or conduction cooled applications. Designs suitable for high power supplies of various ratings for Air, Naval, Ground based and space applications are developed. Products are implemented in VPX, VME, cPCI and custom form factors designs.

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 VHF/UHF Search Receiver, HF Search Receiver, Monitoring Receiver & Jammers.

The Second Launch Pad Count Down system is implemented using VXI hardware designed by Data Patterns specific to the application requirements, featuring a redundant system handling upto 14000 I/O points.

The ATE monitors various aspects of the launch vehicle during this count down phase and assists in automating launch process. This product has been very reliable in operation since 2001. The ATE consists of precision analog input signal conditioners and digitizers and discrete as well as relay logic. One of the specialised modules used for fail/safe automation is an analog comparator which is programmable to carry out safety monitoring, independent of the software for fail/safe operation purposes. This world class system was implemented by Data Patterns against strong competition and proved it's reliability over many launches of the PSLV and GSLV from the Launch Pad.

Data Patterns has designed Fire Control Systems for Missiles, Decoys for Ground, Air and Naval Applications.

Go No Go Testers are developed in portable formats. Typically these are utilized at 'I' Level and 'O' Level test requirements and clear the aircraft LRU for flight.

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 has designed prototyped, qualified and manufactured a wide variety of products intended for airborne applications in manned and unmanned aircraft. Ranging from smaller unmanned vehicles and missiles to manned fighter aircraft, Data Patterns has the largest number of qualified LRUs designed in India from a single source. Incorporating the latest techniques from thermal engineering and mechanical ruggedisation, Data Patterns' products are ideally designed for the application. A captive manufacturing facility enables production with reliability. At the same time, planning and preparing for obsolescence management and providing long term support for manufacturability is the key philosophy with respect to the avionic product lines.

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.

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.

Data Patterns designed and built the BrahMos Missile Checkout Equipment based on the requirements and support of DRDO and BrahMos. This unit validates the complete performance of the Missile through interfacing with it's umbilical and maintenance connections. The shelter mounted checkout equipment is utilized to test the articles on the field during it's life cycle, thus ensuring readiness for launch on demand. It comprises the power supplies, I/O interfaces, specific to type test equipment and VME based systems. This system has been designed for transportability and roadability as per the operational requirements.

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.

The Power Module Checkout ATE is developed for testing DC-DC Power modules typically utilized in India's space program. The DC-DC converters are exhaustively tested for all design parameters including supply voltage range, line and load regulation, efficiency, ripple, noise, transient response and so on. Special power sources and loading mechanisms are deployed to enable testing of various types of power modules.
