Communication is one of the core business activities of ASELSAN. In fact, the first product of ASELSAN in the early 80’s was a conventional military radio family. After that by means of our own R&D activities, we realize the design and the production of Frequency Hopping Radios, which is a standard Tactical Area Communications equipment of Turkish Armed Forces and exported to more than 10 countries armed forces. ASELSAN is also producing Tactical Area Communications System, Satellite Communications Systems, Tactical Communication Products and Crypto and Information Security Products. Today, ASELSAN is one of the few companies in the world, who realizes the design, production and delivery of the next generation Software Defined Networking Radios (SDNR) which are developed to satisfy the tactical and strategic radio communication requirements in the land, airborne and naval platforms. Software Defined architecture of the radios provides a high protection capability against electronic warfare applications. Besides the standalone systems, we are also providing our customers with complete system solutions. For example, ASELSAN provided the Turkish Armed Forces with TASMUS, which is fully mobile and flexible communications architecture that covers any type of communications such as voice, video and data. Main aim of TASMUS is to create a real time picture of the tactical area and to manage necessary real time data communication between the sensors, weapons and command control centre. TASMUS also enables the all army units to be continually tracked and controlled from a command control centre.
