The Bangladesh Navy does not have a tactical communications system as used by other navies and begins a procurement process through international bidding based on the features and capabilities they have observed in NATO LINK-22s.

Tecnobit offers you an innovative system complete with a new ad-hoc protocol called Opelink (NO-OTAN) and secure encryption, to solve this gap between your naval, air and ground units.


Systems are to be integrated on sixteen platforms, including nine surface ships, two submarines, two maritime patrol aircraft and three land stations including the Navy Headquarters in Dhaka. As well as training and coaching of personnel in Spain and on-site.


Based on the Openlink system, a complete system based on a specific Data Link Processor and operator consoles is developed for the Bangladesh Navy, which we call Bangla-22, which allows the exchange and sharing of tactical data from the local sensors of each platform with the rest of the units.

It also incorporates an encryptor, considered a benchmark in secure communications to protect voice and data. Communications between units will be via HF and VHF radio and there will also be provision for satellite connection.


Several tactical communications systems have been developed, implemented and are operational, meeting the highest expectations of the customer, who has launched a new expansion program to incorporate more units to the system and expand its capabilities by integrating other sensors and including satellite communication.

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.
