SAMMANFATTNING
Ericsson Erisoft AB are developing the Command & Control software for ERIEYE - an Airborne Early Warning and Control (AEW&C) system produced by Ericsson Microwave Systems AB. The system is very successful and is currently the only European-built system to enter into NATO service.

The ERIEYE system is mounted aboard an aircraft and consists of a radar and a number of consoles where operators interact with the software. Some of the information presented for the operator is shown in the form of tabular data. Currently there are a number of performance issues related to these tables which need to be solved. Furthermore, the current code base is difficult to maintain, which causes inconsistency between tables and makes changes and enhancements hard to implement.

This Master's Thesis suggests solutions to the problems posed and provides useful data and advices for further development. While these are aimed at the tables in particular, they may well be applicable to other parts of the system.

The analysis and research done show that the problem with performance and maintainability can be solved. By doing a redesign of how the tables are implemented they can be made to handle data in a much more optimized way. The design also allows new tables to be constructed and integrated with ease. Performancewise, the bottleneck that still persists lies on the graphical side and is ultimately caused by the external soft- and hardware on the receiving end. Fortunately, there are methods to overcome even these limitations.

In order to demonstrate the results, a prototype was built based on the selected solutions. This prototype has since then evolved into a more mature version, and is now part of an ERIEYE system for the Hellenic Air Force in Greece.
