2 SpaceNews Home Page November 2017 In-orbit debris removal SSTL-Astroscale collaboration MOU 1-metre colour video from space 5 12 satellite initial constellation Human and Robotic Exploration Commercial Services Lunar Services Partnership ESA, SSTL, GES Disruptive, innovative service companies partner with SSTL 2

3 2018 Launches: Another exciting year for SSTL! Carbonite-2 LEO P1 VNIIEM x 4 Remove Debris SSTL-S1 NovaSAR STSAT VESTA FormoSat-7 x 6 ELSA-d Target Diversity of spacecraft and missions from 3U to ~400kg 3

4 CubeSat Valuable Capability, Utility & Purpose Industry disruption Market-driven response Transition from toys to tools Increasing access to space Big Data analytics and distribution channels Internet everywhere, Internet Of Things Stimulating and Leveraging technology developments Cubesat standards accepted and used Low cost of entry for short lifetime missions Validation of technologies and mission concepts Catalyst for platform and payload innovation Miniaturisation Cubesat subsystems and deployers Payload interfaces Relatively inexpensive components Small size & mass low launch cost Demonstrators and proof of concept Fractionated systems & constellations The problem: Mission limitations due to CubeSat form factor 4

5 Our customers need More The performance of a 100kg+ satellite in 20kg-40kg The performance of a 150kg+ satellite in 50kg Longer Lifetime (5-7 years) Low-cost manufacture, launch & operations Increased payload capacity (mass and volume) Smaller and lighter High accuracy AOCS knowledge, stability, accuracy Increased power generation and storage Better downlink rates Faster processing and data storage Propulsion options for station keeping, phasing, orbit-raising Low Cost doesn t necessarily translate to High Customer Value 5 Small satellites need to enable sustainable business models

6 SSTL-42 Flexible Baseline Configurations Standard Power Variant <40kg platform Payload OAP >15 W continuous 25% power increase possible with 1-axis tracking arrays Up to 75 kg payload mass 55 x 55 x ~60 cm High Power Variant <50kg platform Payload OAP >80W continuous 25% power increase possible with 1-axis tracking arrays Compatible with km altitude orbits Compatible with a wide range of launchers, including PSLV, Falcon-9, Falcon Heavy, Soyuz S-Band Uplink 19.2 kbps S-Band TTC Downlink 38.4 kbps S-Band Payload Downlink 4 Mbps X-Band Payload Downlink 400 Mbps Payload Data Storage 256 Gbyte Dedicated payload radiator Reliable, accurate AOCS; options includes star tracker, propulsion Flexibility allows tailoring for customer-specific needs in LEO 6

7 Highly-integrated avionics make it possible The Core Data Handling System (CDHS) The Core DHS Effect Dual-redundant functionality in a single unit On-Board Data Handling Flight Software: platform & payload health, operational & mission tasking Attitude and Orbit Control System Telemetry and Telecommand RF Supports different payload interfaces UKDMC-2 CoreDHS Significant mass, power, volume, real estate savings from CoreDHS, Payload Chain Card and half-size BCM & PDM 7 Engineered for automated manufacture and test Lower Costs

8 Next: More Miniaturisation and Automation Standard Power Variant High Power Variant Payload OAP >15 W continuous Payload OAP >80W continuous Up to 75 kg payload mass External: 550 x 550 x ~600mm Internal: 200 x 200 x 200mm Payload bay with central recess for internal mounting of a telescope or a high-dv system Compatible with a wide range of launchers, including PSLV, Falcon-9, Falcon Heavy, Soyuz Customers benefit from SSTL s industrial approach

9 SSTL s proven approach to mission success UoSAT-1, 1980 Challenging cost targets Delivering performance associated with more expensive systems In-depth knowledge of using COTS components RapidEye, 2008 UoSAT-12, 1999 SNAP-1, 2000 GIOVE-A, 2005 Leveraging new developments in technology and processes Offering flexible, reconfigurable avionics Building on in-orbit Heritage and Endto-End system engineering Industrialisation of production Developing smaller, more resourceefficient systems Designing for mission lifetimes that enable Return On Investment SSTL-42: Continuing to deliver More for Less DMC3, 2015 Carbonite-2, 2018 Telesat LEO P
