Same Problem Needs the Same Solution: AYESAŞ

UPGRADING THE LEGACY COMMAND CONTROL SYSTEM

AYESAS We are developing trust with every line

AYESAS, an abbreviation of Aydın Yazılım ve Elektronik Sanayi A.Ş., has an excellent reputation in the defence industry with its software and electronics based activities with a history that began with the Command, Control and Communications System for Turkey’s national air defence system.

It has gained significant experience and built unique capabilities in the areas of real time software development (command control, radar integration, tactical data link and avionics software), mobile defence electronics equipment production and system integration including shelter design & installation. Furthermore, it becomes a company that can provide a whole solution including the all life cycle activities of a product such as depot level maintenance, logistics support and upgrading the systems with balancing the evolving operational requirements and current state of the art technology.

The system designed & developed by AYESAS in the early 1990’s, receives plot information from multiple radars, establishes tracks and correlates them with information received from the tactical data links. The air picture is displayed on a Situational Awareness Display for the use of the Operator.

Advanced identification feature allows the system to provide hostile/friend information regarding tracks. The system performs automated threat evaluation for targets using available airbases, intercepts and Surface to Air Missile (SAM) sites.

We have further enhanced the command control competencies, skills and capabilities by participating various radar and communication systems integration projects in Turkey and in various NATO countries. Those projects include the automation of manual radars, radar integration, converting radar specific messages to the generic message set, delivering the messages to command control centers via common interface and remote controls of radars. Currently this accumulated knowledge is being used in various projects of Turkish Armed Force and our customers are completely satisfied for the aspects of quality, cost and schedule performance. We obtain a profound knowledge of our application domain and architecture. Our experience shows that capable domain architecture practice provides the foundation for software reuse, and benefits from capable requirements determination and specification practice.

Capabilities, competencies and experiences in the command control domain can be further divided into three main subsections as follows;

• Command and Control Systems including multiple radar tracking, identification and control, intercept geometries, SAM intercept calculations and decision support systems, simulation, recording and playback, real time embedded software development, fire support automation, technical and tactical fire control and geographical information systems.

• Radar Integration Systems necessitates graphical user interface, real time plot analyses, remote control and monitoring of multiple radars, real time transmission of radar data to command control systems, message protocols for air defence radars and software tool kit for new radar integration.

• Tactical Data Communication Systems that requires real time data transmission for the TADIL A (Link-11), TADIL B (Link-11B), TADIL J, ATDL-1, NATO Link-1, Link-16 Protocols including the adaptable mission computer interface.

• Tactical Display Software with reach Graphical User Interface supporting various GIS formats including S-57 maps for Naval applications.

Currently, AYESAS is in the stage of preliminary study on how to modernize and upgrade a command control system that employs early 1990’s technology. Since the systems are complex and expensive, their operational life should be further extended. That means some obsolete components and systems that are no more supported by the vendors should be replaced, software should be migrated to the new processing environment that is suitable for employing new software technologies, upgrade target operating systems and utilize new graphic intensive human machine interfaces.

Applying middleware to separate the application software from the hardware platform is the important step for the upcoming modernizations and new software features implementation.

Developing and maintaining such a large software intensive systems requires;

• The development processes have to be predictable with respect to cost, schedule and quality; • Productivity has to be measured persistently throughout the all life cycle activities (requirements, specification, design, code, test, and operations), • Traceability has to be established and sustained among life cycle artifacts, • Statistical process control in the management and engineering has to be applied.

To meet the above objectives; we understand our own current practice which is based on performing persistent measurement of our productivity through all life cycle activities. We have established and sustained traceability among life cycle artifacts including requirements, specifications, designs, code, and test procedures.

AYESAS Software Group has been appraised at SEI SW-CMM Level 3 on May 1st, 2003. Our process improvement effort continues since then and we are planning to have an appraisal for SEI CMMI Level 5 in Q2 2007.

Today, our software engineering processes are proven and customized for RTCA DO-178B and MIL-STD-498 (as well as IEEE 12207 which replaces it), as well as certified by both ISO 9001:2000 and NATO AQAP 160 systems.

Aydın Yazılım ve Elektronik Sanayii A.Ş. (AYESAŞ) has been serving Turkish and international customers in Aerospace and Defense (A&D) Industry since 1990. Starting with the establishment of a Command-Control- Communication-Computer- Intelligence (C4I) system as Turkey’s national air defense system called Turkish Mobile Radar Complexes (TMRC) Program; AYESAŞ developed highly specialized Software, Hardware and Production expertise in C4I Systems, Avionic Products, and Electro-Mechanical Systems.
