Infrared Search and Track System – Infrared Search and Track (IRST)


Eurofighter Typhoon / Frigate F-110


Aerospace and Defense | Naval

Capabilities used

  • Systems engineering.
  • Image processing algorithms.
  • Detection and tracking algorithms.
  • Real-time processing.
  • Graphic representation systems.
  • Artificial Intelligence (AI).


For three decades TECNOBIT- Oesia Group has been designing and developing Infrared Search and Tracking Systems, more commonly known by its acronym IRST (Infrared Search and Track).

IRST systems are based on a series of electro-optical sensors providing the platform with a system capable of detecting and tracking multiple targets automatically from their thermal emissions, without emitting any radiation, which significantly increases the stealth capability of the platform.


During this stage and through our participation in various programs, TECNOBIT- Oesia Group has developed all the technological blocks of the IRST systems including:

  • Optronic sensors.
  • Real-time processing system.
  • Image processing algorithm.
  • Algorithm for detection and follow-up.
  • User interface.


Our infrared search and tracking solutions are present in airborne platforms, Eurofighter Typhoon, and naval platforms, F-110 Frigate.

Firstly, our participation in the EUROFIRST consortium participated by Selex ES (Italy), Tecnobit (Spain) and THALES Optronics (UK) meant the participation in the Eurofighter Typhoon program for the development of the PIRATE, which allowed Tecnobit to be at the forefront of Spanish companies in the development of infrared search and track systems.

The PIRATE not only provides thermal imaging (FLIR), but also incorporates IRST capability, automatic target search and detection, making it the most advanced sensor on the market. TECNOBIT-Oesia Group's responsibility in this project includes the development and production of video chain processing electronics and the image processing algorithms. The responsibility of TECNOBIT-Oesia Group in this project includes the development and the production of all the electronics that compose the video chain and part of the tracking electronics including the image processing algorithms.


Thanks to our successful participation in the design and development of the PIRATE FLIR, TECNOBIT- Grupo Oesia was selected, in collaboration with INDRA, to undertake the design and development of the IRST system for the next generation of the Spanish Navy's F-110 frigates. This new project, in which we are responsible for developing the image processing and detection algorithm, the processing core and optronic blocks for both detection and identification, represents a technological milestone at national level, since for the first time IRST systems will be incorporated to our naval platforms, which will significantly improve the capacity for autonomous surveillance in a maritime environment.


Family of SATCOM On The Move (SOTM) terminals for vehicular installation and stable mobile connection

SGoSat is a family of high-tech SOTM (Satellite Comms On The Move) terminals that are installed in a vehicle, providing the ability to target and maintain a stable connection to the satellite when the vehicle is in motion in any type of conditions.

The SGoSat family is composed of versatile terminals, which can be installed on any type of platform: trains and buses, military and/or government vehicles, aircraft, ships, etc. Originally designed for the military sector, SGoSat terminals are extremely reliable and robust, integrating high-performance components that comply with the most stringent environmental and EMI/EMC regulations. The product uses low-profile, high-efficiency antennas and a high-performance positioning and tracking unit, allowing the terminal to be operated anywhere in the world.

In order to meet the diverse needs of its customers, INSTER has developed single band and dual band terminals in X, Ka and Ku frequencies.

The SGoSat family of terminals can also be configured with a wide range of radomes (including ballistic options) to suit customer requirements.
