e Concurrent Design Facility beyond phase A: project manager perspective Dr. Anton B. Ivanov Adrien Corne EPFL Space Center (eSpace) e Outline • Our setup • Our projects • My perspective - use of CDF tools for programmatic documentation - use of CDF tools for Validation and Verification activities - model validation 2 e “V-Model” of Systems Engineering Stakeholder     Systems  Engineering   Lifecycle     Analysis Overview Management Requirements   System   Commissioning   Defini<on Safety Opera<ons System  Architecture   Verifica<on  and   Concept  Genera<on Valida<on,  Change  Mgt Tradespace  Explora<on   System  Integra<on   Concept  Selec<on Interface  Management Concurrent  Engineering   Mul<disciplinary  Op<miza<on 3 e “V-Model” of Systems Engineering Stakeholder     Systems  Engineering   Lifecycle     Analysis Overview Management Requirements   System   Commissioning   Defini<on Safety Opera<ons System  Architecture   Verifica<on  and   Concept  Genera<on Valida<on,  Change  Mgt Tradespace  Explora<on   System  Integra<on   Concept  Selec<on Interface  Management Concurrent  Engineering   Mul<disciplinary  Op<miza<on 3 e CDF at the Space Center 4 e CDF at the Space Center 4 e CDF at the Space Center 4 e Implementation approach • In order to prepare an initial design of a system we need - models that describe behaviour of various components (often these models depend on one another for parameters) - databases containing components - models + databases = system - all inside J-CDS (now RHEA) CDP infrastructure ‣ now moving towards Open Concurrent Design Tool (OCDT) • Models - we have created all models for a small satellite - models are implemented in an engineering software set - MATLAB for AOCS, payload analysis - CATIA or SolidWorks for mechanical properties - ESATAN/ESARAD for thermal analysis - AGI STK for mission simulation, power and data budget calculations 5 e CubETH: GNSS experiments in 1U Angular norm speed 2009-->2012 • Key science and technological objectives 600 BGDyrOo T2 0O0n9 Gyro post 2011 Rate from audio 500 - Precise Orbit Determination (GPS, GLONASS and Galileo demo) 400 - Experiments: radio occultations, reflectometry, air density g/s de300 - Satellite structure manufacturing for easy assembly 200 100 - Microelectronics demonstration: ultra low-power AOCS 0 0 200 400 600 800 1000 [days] - Distributed ground stations for command and download SwissCube heritage: almost 5 years of operations Cubesat Overview Volume 1U (10x10x10cm) Mass 1.3 kg (per standard, TBC) Power 1.7 W (SwissCube) Project Partners Data rate 9600 bps Payload ETHZ, HSLuzern, HSRapperswil Payload 11 uBlox GNSS receivers Systems Engineering EPFL 6 antennas AIT EPFL Operations Distributed Ground Stations Orbit 500km, SSO, 2AM/2PM Industrial partners uBlox, RUAG, Saphyrion, CSEM Launch 2016 (TBC) Academic partners LEMA, RISD, 6 e CubETH: GNSS experiments in 1U Angular norm speed 2009-->2012 • Key science and technological objectives 600 BGDyrOo T2 0O0n9 Gyro post 2011 Rate from audio 500 - Precise Orbit Determination (GPS, GLONASS and Galileo demo) 400 - Experiments: radio occultations, reflectometry, air density g/s de300 - Satellite structure manufacturing for easy assembly 200 100 - Microelectronics demonstration: ultra low-power AOCS 0 0 200 400 600 800 1000 [days] - Distributed ground stations for command and download SwissCube heritage: almost 5 years of operations Cubesat Overview Volume 1U (10x10x10cm) Mass 1.3 kg (per standard, TBC) Power 1.7 W (SwissCube) Project Partners Data rate 9600 bps Payload ETHZ, HSLuzern, HSRapperswil Payload 11 uBlox GNSS receivers Systems Engineering EPFL 6 antennas AIT EPFL Operations Distributed Ground Stations Orbit 500km, SSO, 2AM/2PM Industrial partners uBlox, RUAG, Saphyrion, CSEM Launch 2016 (TBC) Academic partners LEMA, RISD, 6
