Introduction
The main systems of the ground segment infrastructure (e.g. SCOS-2000, SIMSAT, Station Computer, Ground Station’s Systems, etc) include a variety of Man-Machine interfaces.
Currently, each individual product has its own specialised approach.
Different technologies, different look-and-feel.
EGOS Purpose
Some background information. What is EGOS ?
common approach to data systems infrastructure development.
common set of services used by all ESA Ground Segment applications.
distributed development of a suite of commonly usable new / adaptive middleware software tools
Reduction of development costs on infrastructure and mission specific developments.
Enables interoperability across systems.
Enables common software maintenance policy and a long-term maintainability of the Ground Data Systems.
Reduces the familiarization efforts
EGOS elements and the EUD role
EGOS User Desktop OBJECTIVES
To provide the EGOS applications with a standard interface to the operator, that is decoupled from the base “underlying” system’s processing layer
Achieving a harmonised implementation of the MMI capabilities (display of data, user’s inputs etc).
To standardise the look & feel of all EGOS applications.
To provide the standard interface for interaction with the EGOS framework.
EUD Features
The EUD provides the Presentation layer to the EGOS applications.
The initial EUD implementation foresees communication with the EGOS System via CORBA messages: this allows the presentation layer to be present locally or remotely with seamless interfacing.
The EUD architecture allows also different communications technologies (e.g. http-based protocols)
The data contents of the displays is done via text configuration files (XML).
EUD Software Architecture
EUD consists of:
EUD Framework : provides generic runtime environment for EUD displays, and the means to interface the any EGOS system
Displays library : a set of display plug-ins which provide the specific GUIs (e.g. ANDs, messages displays etc).
EGOS UD Top-level architecture Framework
Service Proxy Home
Within the Framework, the communications with the underlying system are managed via the Service Proxy Home.
The Service Proxy Home abstracts the communication with the processing layer.
It provides the EUD Displays with the necessary logic for accessing the EGOS services.
ServiceProxys and EGOS services
EUD deployment scenarios
Diverse deployment scenarios:
Communication via CORBA messages: the EUD can run either locally or remotely with respect to the busyness logic of the EGOS system
Communications via http protocol: the EGOS system is remotely distributed
EUD deployment scenarios EGOS System in a standalone environment EGOS System in a distributed environment
EUD deployment scenarios EGOS System remote distributed environment
TECHNOLOGY
The EUD is based on the Eclipse platform
Java technology for platform-independent applications
EUD Technology
Eclipse features:
open-source, platform-independent, written in Java, for building "rich-client” applications.
It runs on multiple operating systems, so it is adaptable to different operational requirements within the ESOC ground segment.
native look and feel on major platforms (e.g. Linux, Solaris and Windows) thanks to the SWT graphic library, standardized component model, extensibility and integrated update mechanism.
Allows easy tailoring and extension of the basic platform, by means of plug-in (e.g. in the EUD the Displays and the Service Proxy, according to the operational requirements).
Eclipse Plug-in Architecture
Eclipse has an open architecture based on plug-ins which are built on a platform runtime
The plug-ins are layered through extensions to lower-level plug-ins providing new functionalities for the underlying plug-ins.
The plug-in is the mechanism of extensibility in the Eclipse platform. New plug-ins can add new functionalities to existing plug-ins.
The plug-in is the smallest unit of the Eclipse platform function that can be developed and delivered separately.
The platform runtime core implements the runtime engine that starts the platform base and dynamically discovers and runs the plug-ins.
The following figure illustrates the different plug-ins layers
Eclipse Plug-ins interactions
Eclipse’s Workbench, Perspectives and Views
Workbench – it is a plug-in which implements the user interface and defines a number of extension points that supports other plug-ins contributions
Perspectives – A perspective is a set of views or editors disposed in the workbench window. It defines the initial visibility, the layout and the action visibility
Views and Editors – are the draggable parts that make up the bulk of a workbench window’s contents, through the perspectives. They are visual elements that work as containers of widgets (buttons, tables, etc)
EUD Displays
The initial EUD design foresees a basic set of Displays (Views): ANDs, Message Display, Navigation Tree, Task Display etc).
In the next project phase, more sophisticated or system-specific displays will be developed (scroll display, history display, mimic capability) etc.
The new Displays will be plugged-in

EUD preliminary look and feel
The EUD Launcher
The EUD Launcher: specific tailoring of the EUD framework, for controlling and monitoring multiple EGOS systems from a centralised position;
Start-up and Shut-down EGOS systems;
Monitor and Control EGOS systems, via a set of dedicated displays.
The EUD Launcher
Project Status
EUD Phase 1 (in 2006) :
SW Requirements Specification- SW Req. Review;
SW Design Document – PDR;
Prototype.
EUD Phase 2 (in 2007-2008):
Consolidation of Phase 1 results;
Delta -SW Design Document – Delta PDR;
SW Detailed Design and Coding;
FAT and first SW delivery by June 2008;
Integration into SIMSAT for validation.
Functionality in Preparation
A comprehensive Mimic capability is under definition, and will be added to the basic EUD
It will be developed based on Eclipse native tools (e.g. GEF)
It will be plugged-in to the basic EUD project as any other component

The EGOS User Desktop is defined as a part of the E more
The EGOS User Desktop is defined as a part of the EGOS (ESA Ground Operation Software) project and provides the building blocks and the framework to support the user with front-end for monitoring and controlling of applications. The main systems of ground segment infrastructure (e.g. SCOS-2000, SIMSAT, Station Computer, Ground Station Systems, etc.) include a variety of applications that support the user while monitoring and controlling the status of the system. Currently, each individual product has adopted its own specialised approach and tools for the monitoring and control aspects. less
