Capabilities used

  • Systems engineering.
  • Design and development of on-board electronics.


The Spanish Navy needed to modernize, with new equipment that would provide it with new technological capabilities. It needed to be upgraded with a multitude of state-of-the-art equipment, such as air and surface radars, missile launching systems, artillery, sonar, electronic warfare equipment, optronic surveillance systems, among others.

Tecnobit, thanks to the knowledge acquired by its international programs in IR technology, began the development and design of its own optronic systems on a 4-axis stabilized platform with the ARGOS system.


Development of a 4-axis stabilized electro-optical system with the following characteristics:

  • Alignment of sub mRad sensors.
  • Day and night observation/surveillance with detection, recognition and identification capabilities.
  • Standard configuration with three sensors:
  • FLIR CASTOR MWIR high resolution camera.
  • High resolution color CCD and continuous zoom.
  • Eye safe" laser rangefinder.
  • LOS and working point can be integrated with other navigation and surveillance systems. Possibility to slave the system to other sensors to facilitate target identification.
  • Automatic tracking of maritime, air and land targets.
  • Automatic scanning of predefined zones in scan mode.
  • Video recording from the control panel.
  • Navalized" system, operable in extreme environmental conditions.
  • Possibility of incorporating automatic alarms for the appearance of targets.
  • Up to three operator connections, local control or external system.


The ARGOS optronic system is developed, specially designed for detection, recognition, identification and interception applications, as well as navigation assistance in poor visibility or night conditions. For this purpose, in addition to the IR sensors, it has an automatic tracking capability that allows the target to be "tracked" so that it can be followed so that it is not lost from the field of view at any time.

Design, development, production, installation and service support of 4-axis stabilized optronic systems for surveillance and observation functions.


Since 2003, when the first optronic system was installed in the Santa María Frigate, the first optronic systems have been continuously expanded to include the number of units installed in almost all ships in service of the Spanish Navy, reaching 29 ships with Tecnobit optronic systems and also in shore stations that support the security tasks of the Spanish coasts and in surveillance operations both in national territory as well as in other countries.

In addition, Tecnobit - Oesia Group carries out the integral support of its systems, which guarantees the optimal fulfillment of the optronic systems' life cycle with services adaptable to the specific needs of each equipment, assuring the maximum operative availability at any time and place.


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.
