AGENDA


They mainly collect and maintain all the knowledge related to spacecraft M&C

(e.g. TM/TC) for allowing:

• On board SW development

• System AIT

• Delivery of data for in-flight operations

SPACECRAFT REFERENCE DATABASES (SRDBs)


Verify that the SRDB data delivered by the Space Segment (Prime) to the

Ground Segment (Operations) are valid and complete according to the ESA

project requirements.

SRDB DATA


The TEC-SW-SRDB projects support includes:

• The verification of the compliance of the delivered data with the applicable

ICDs

• The verification of the compliance of the delivered data with the applicable

validation rules

• The identification of the changes occurred among deliveries

• The impact analysis of occurred changes for non-regression tests

TEC-SW SRDB PROJECT SUPPORT (cont’d)


TEC-SW-SRDB Applications are the main means for this project support.

Several Applications have been developed during the last years complying with

the project specific data requirements.

This experience has identified for this type of applications:

• Main functional requirements

• High-level architecture

Many Product Areas, one for each SRDB data delivery

One Administration Area, managing all SRDB data deliveries


For each project a specific TEC-SW-SRDB application is developed:

• based on the same Architecture

• implementing the same type of functionalities (Import, Export, Consistency

checks, …)

BUT

• with data models that differ i.e. project specific

• resulting in project specific interfaces (Import, Export, MMI, …)

CONCLUSIONS

AGENDA


ESA-ESTEC needs to:

timely and cost effectively (i.e. in line with the project schedule and constraints)

produce means to assess the SRDB data quality by automatically

generating the TEC-SW-SRDB applications in compliance with the

project specific model requirements.

CONCLUSIONS

AGENDA


Through the years, many TEC-SW-SRDB applications (e.g. SSM, METOPDB,

SSDB, CSDB, FEDs, VIDB) have been developed in support to projects such as

METOP, VEGA, IOV, Sentinels, EarthCare, FOC.

The SIB TEC-SW-SRDB application is the result of this evolution:

• Moving from a client-server to a three-tier Deployment

• Fully model-driven application specification, design and development:

– SIB Application Framework Software, able to adapt its behaviour to the

input model

– SIB MMI automatically generated according to the input model

SPACE SYSTEM BASE (SIB) APPLICATION


Classic three-tier deployment allowing:

• Seamless remote access

• No client installation (standard Internet browsers)

• Performance isolation and optimization on server tiers
