TechDemoSat-1 & NovaSAR-S Lily Dodemant / Peter Fletcher UKSA Ground Segment Team 6th June 2012 http://www.bis.gov.uk/ukspaceagency
TechDemoSat-1 Objectives A technology demonstration satellite project part-funded by the UK Technology Strategy Board (TSB) and the South East England Development Board (SEEDA) TechDemoSat-1 will be a combined orbital testbed and showcase for some of the UK s most promising space technology It will provide participating organisations early flight heritage overcoming a traditional barrier to market acceptance Includes commitment to host a sensor for a UK schools experiment
TechDemoSat-1 Implementation Project lead by Surrey Satellite Technology Ltd (SSTL) Mini-satellite based on the SSTL-150 platform (as used for RapidEye) Will carry nine payloads with additional innovative subsystem designs Particular emphasis has been placed on enabling the operation of individual payloads with minimal system contention Launch date currently scheduled for early 2013 Three year mission
TechDemoSat-1 Payloads Four separate suites of instruments: Maritime SSP: Sea State Payload (SSTL) Space Environment MuREM: Miniature Radiation Environment and effects Monitor (SSC) ChaPS: Charged Particle Spectrometer (MSSL) HMRM: Highly Miniaturised Radiation Monitor (RAL) LUCID: Langton Ultimate Cosmic ray Intensity Detector (Langston Star Centre) GARASH: Gradiometer And RAdiation SHield (RAL) Air and Land Monitoring CMS: Compact Modular Sounder (Oxford University and RAL) Platform Technology De-orbit sail (Cranfield University) CubeSAT Attitude determination and Control Subsystem (ACS) (SSV)
UK mission: led by Industry, part funded by UKSA, Technology Strategy Board (TSB) & Industry S-band SAR Low cost lightweight small satellite 3-satellite constellation to achieve global daily coverage Project KO: Q4 2011 Launch: 2014 Mission lifetime: 7 years NovaSAR-S
NovaSAR-S applications Flooding Disaster Monitoring NovaSAR airborne payload demonstration - Forestry Forestry Crop monitoring and classification Land cover & land use classification Ice Monitoring NovaSAR airborne payload demonstration - crop classification Maritime Ship detection Ship wake detection Oil spill detection SAR & AIS data combination
NovaSAR-S mission highlights (1/2) SSTL-300 bus avionics, SSTL bus, Astrium payload Small secondary payload being considered (AIS?) Direct in orbit tasking & encrypted data downlink Designed to operate independently or in a constellation Optimised for shared launch Range of modes from high resolution to wide area coverage
NovaSAR-S mission highlights (2/2) Major milestones completed: Airborne trials validating S-band imagery NovaSAR airborne payload demonstration - ship detection Spacecraft Preliminary Design Review Payload demonstration producing inverse SAR image of International Space Station GoogleEarth
NovaSAR airborne payload demonstration NovaSAR-S applications & service development Level 1 Single Look Complex systematically generated Higher level products & value-added services: Commercial tools (migration of algorithms) Open access for non-commercial applications development Collaboration with Satellite Applications Catapult Centre for commercial applications development
NovaSAR-S & TDS-1 Ground Segment Primary facilities hosted by ISIC s Operations Centre at Harwell, UK: Ground station antennas (S and X-band) Spacecraft operations (NovaSAR only) Payload operations Data processing & archiving (raw & L1 SLC) Service interface SSTL/DMCii facilities used as backup For NovaSAR: 15% of capacity will go to UK government Method for capacity sharing TBC (depends on future partners)
TechDemoSat-1 & NovaSAR-S as precursors TechDemoSat & NovaSAR concepts will provide ongoing stimulus and support to science and commercial development Closely linked to Satellite Applications Catapult centre (announced January 2012) that will provide UK businesses, including SME s, unique access to advanced systems for data capture and analysis to support the development of new services delivered by satellites
