Company Presentation
OHB Sweden
Part of OHB Group Specializes in
Small Satellite Systems Attitude and Orbit Control Subsystems (AOCS) Propulsion Subsystems
On-going projects Small GEO AOCS and Electric Propulsion (telecom) European Data Relay Satellite AOCS (telecom) Electra AOCS and Electric Propulsion (new all-electric telecom platform) Solar Orbiter AOCS and Propulsion (ESA M-class scientific mission) Innosat/MATS (latest Swedish National Research Satellite) Several studies within Formation Flying, high-altitude GNSS navigation, propulsion technologies

Technology Needs
Telecommunication Satellites Trends within telecom:
Telecommunication Platforms with Electric Propulsion only for Comple Transfer Phase (low-thrust transfer) On-Station Operations
On-board GNSS navigation for efficient transfer and on-station control Co-location of several satellites within same operational slot
On March 11 2016, The OHB Group, SES, and ESA signed the contract for Electra – a European fully electric telecommunication platform
OHB Sweden Contributes with Electric Propulsion and AOCS
A strong need for OHB Sweden to develop strategies for autonomous co-location of telecommunications satellites with on-board GNSS and Electric Propulsion

Technology Needs
Formation Flying OHB Sweden has unique knowledge within Formation Flying and Rendezvous from the PRISMA
mission OHB Sweden conducted dedicated GNC-experiments within Passive formations, Forced Motion,
Autonomous Rendezvous, Orbit Safety Multi-spacecraft formations are expected to be an important component in future space systems and
more than two spacecraft was originally on the wish-list for PRISMA Multi-spacecraft formations is a natural extension from the dual-spacecraft PRISMA mission and OHB
Sweden needs to gather further knowledge in this area in preparation of future formation flying applications
The following areas have been selected for study: Failure tolerance and guidance architectures Multi-agent performance enhancement mechanisms Optimal and robust reconfiguration
All three areas are strongly interrelated and treat problems that will be necessary to tackle for any future Multi-Spacecraft application:
How will the formation be controlled? How can the participants cooperate in the best way? How is this done while maintaining mission safety?
