The European SSA Programme - Definition

The Space Situational Awareness (SSA) is defined as a comprehensive

knowledge, understanding and maintained awareness of:

the population of space objects;

the space environment;

the existing threats/risks.the existing threats/risks.

Advanced Software Technologies for the European Space Situational Awareness| GSAW 2010 | Page. 2

The European SSA Programme - Objective

Support the European independent utilisation of and access to space

Provide timely and quality data, information, services and

knowledge regarding the environment the threats and theknowledge regarding the environment, the threats and the

sustainable exploitation of the outer space surrounding the Earth


The European SSA Programme – Phased Approach

Phase-1: The SSA preparatory programme, 2009 - 2011 Specification of the System Requirements and the Architectural Design for the

future European SSA System

Deployment and operation of SSA Precursor Services

Phase-2: The SSA full programme, 2012 -2020 Deployment and operation of the full European SSA system Deployment and operation of the full European SSA system

SSA Data Systems - Objectives and Constraints

Rapid provision of SSA precursor services, already in 2010

Federation of existing assets Integration of legacy applications

Provision of timely (highly available) and quality (QoS) services Primarily focus on web-based service provision Primarily focus on web based service provision

Handling of classified data and system critical applications Implementation of strict security and safety requirementsp y y q

Geographically distributed setup for sensors and the data centres
