In the space community, there is a strong interest in formation flying or swarm missions with small satellites. This could open the door to new exciting applications in earth observation, telecommunication or in-orbit servicing. Such missions are expected to have important benefits in terms of low system and deployment costs, distributed sensor capability or high reliability due to redundancy. In order to take advantage of a swarm configuration, a communication concept is required, which deals in a generic way with specific space environments and is able to cope with frequent topology changes. Up to now, space communication has only addressed static inter-satellite links (ISL), mainly based on proprietary protocols. In this paper, we propose to adopt well-known terrestrial communication standards. Such standards have been proven to be well conceived for a wide range of applications. WiFi is one prominent representative of such candidates which includes the ability of ad-hoc networking in order to provide decentralized and distributed wireless networks. Space specific requirements demand minor adaptions of the communication protocols. COTS components are also suitable for such protocols with minor changes. This paper studies these adaptions in depth, both in theory and by simulations and is therefore an important step towards its realization. To our knowledge, there is currently no suitable communication technology which has been adapted for swarm missions with small satellites.
Swarm missions are a promising approach for novel space applications, increasing operational robustness and flexibility. The communication within swarms is one main field of research in the project “BayKoSM - Bayerische Kompetenzen für Schwarm-Missionen”, which will make contributions to different technological areas of swarm missions. Swarms of small satellites in low earth orbits will be used to execute cooperative tasks. Hereby, new challenges to communication networks are arising which require investigation of specific protocols and communication devices. This paper analyses different communication and energy issues for an implementation of a swarm mission in space.
An accurate forecast of flare and coronal mass ejection (CME) initiation requires precise measurements of the magnetic energy buildup and release in the active regions of the solar atmosphere. We designed a new space weather mission that performs such measurements using new optical instruments based on the Hanle and Zeeman effects. The mission consists of two satellites, one orbiting the L1 Lagrangian point (Spacecraft Earth, SCE) and the second in heliocentric orbit at 1AU trailing the Earth by 80° (Spacecraft 80, SC80). Optical instruments measure the vector magnetic field in multiple layers of the solar atmosphere. The orbits of the spacecraft allow for a continuous imaging of nearly 73% of the total solar surface. In-situ plasma instruments detect solar wind conditions at 1AU and ahead of our planet. Earth-directed CMEs can be tracked using the stereoscopic view of the spacecraft and the strategic placement of the SC80 satellite. Forecasting of geoeffective space weather events is possible thanks to an accurate surveillance of the magnetic energy buildup in the Sun, an optical tracking through the interplanetary space, and in-situ measurements of the near-Earth environment.
