From Perspective to Future Baseline |
|
Since the beginning of development in 1988, the SASS-C software has been under constant evolution to cope with supplementary user requirements, to cover surveillance technology upgrades and to follow software technology changes.
In order to prepare SASS-C for the next decade, important software re-engineering has been undertaken in conjunction with functional upgrades, with the aim to introduce up to date technologies in all relevant fields while enhancing system quality. The main functional upgrades relate to the introduction of Aircraft Derived data (Mode S and ADS), and multilateration technology in the Surveillance environment.
The SASS-C software re-engineering is referred to as modularisation and was commenced at the end of 2003. the objective is to have a full evaluation of: It consists in migrating upgraded functionality into four different independent suites, interoperable through common interfaces called CSDF (Common Surveillance Data Format).
The four suites are briefly described below:
|
|
|
|
- MAS (Multi-Source Acquisition Suite) is the front element of SASS-C handling Surveillance Data from various sensors. The functionality comprises decoding, recording and replay, statistics computation and display capabilities.
- TRES (Trajectory reconstruction and Evaluation Suite) is the core suite of SASS-C, carrying out the reconstruction of reference trajectories from the input data, and doing the evaluation of Surveillance constituent’s performance.
- SMART (Simulator for Multi-radar Analysis from Realistic Traffic) is an upgrade of the present real-time simulator generating Surveillance data reports by sampling simulated aircraft trajectories.
- SCAS (Surveillance Coverage Analysis Suite) comprises RASCAL and CAPT (Coverage And Planning Tool for ADS-B and TIS-B), a new tool to aid in the positioning of ADS-B and TIS-B ground stations by assessing various communication load scenarios.

The new generation of SASS-C made up with the complete set of Suites is expected to be available by the end of 2010.
