ASCOSA study
Customer/Partner
ESOC
Description
During the last few years the Spacecraft Control and Operations System (SCOS) has been improved and consolidated by adding new functionalities and revising existing ones. While these improvements have made the system more powerful, they have added extra complexity, making the maintenance more difficult.
The ASCOSA study (Analysis of SCOS-2000 Architecture) aimed to define a partitioning of the kernel into subsystems with well-defined interfaces, in order to reduce the complexity and make the maintenance of the existing code easier. The starting point consisted in an assessment and evaluation of the architecture and development environment of v2.3e based on specific ISO 9126 quality metrics. Several deficiencies and sources of potential problems have been uncovered.
Based on the evaluation, the study has addressed the partitioning for both the architecture and the development environment. In terms of architecture, slight and medium changes have been proposed, as well as possible scenarios for evolving the system.
Concerning the partitioning of the development environment a layering scheme has been proposed, taking into consideration the need to minimize the impact of refactoring the system, as well as the requirement of assuring a modular environment with reduced complexity. The implementation of this partitioning shall take place in future versions of SCOS-2000, namely version 3.1.

SCOS-2000 Produtization
Customer/Partner
ESOC
Description
SCOS-2000 spacecraft control system framework is the third generation of Mission Control System developed by ESA/ESOC after MSSS and SCOS-I. Since then, a number of missions have been supported and the software has been continuously improved.
So far SCOS-2000 software is being developed based on ESOC environment and constraints. In view of a wide distribution of the software within the European Space community (SCOS Community), a set of improvements has been identified to maintain SCOS-2000 quality and allow an easy access to the SCOS technology for new projects.
SCOS-2000 Produtization aims to promote of SCOS-2000 and the related software infrastructure as a software "product". The project includes the execution of a general software quality improvement, the development of user/customer oriented documentation, the production of packaging and marketing materials targeting SCOS-2000 customers and the improvement of the maintenance process.
A web site with discussion forums, a knowledge based system, mailing lists, FAQ, general documentation, etc shall be also developed to promote the product within the SCOS community.

Engineering Support to European Technology Harmonization of the Ground System Software
Customer/Partner
ESOC
Description
Over the past years efforts have been made in Europe to harmonize the space technology with the objective to have more cooperation and specialization, and strengthen the competitiveness of the space industry. The roadmap of the Harmonization for 2003 includes Ground Systems Software, initially restricted to Mission Control and EGSE and then broadens to include the other ground system components (Flight Dynamics, simulators, Data archiving and mission planning).
The objective of the project is to provide engineering support to the Steering board of the Ground System Software during first phases of the harmonization roadmap.
The engineering support of the 1st phase foresees a preliminary analysis of the Ground Segment requirements, forwarded by the consolidation of this data into high level requirements and services and the definition of a reference architecture. The reference architecture is described using the RM-ODP framework. RM-ODP is a standard for modelling distributed open systems architectures, using an object-oriented and structured approach, which has been issued by the International Telecommunications Union (ITU-T) and the International Organization for Standardization (ISO).
The 2nd phase is dedicated to producing interfaces between the key components identified in the architecture.
