“…almost the starting point of bringing a big amount of rather online flexibility to already installed planning software components. By now, they provide a huge scope of functionality that has been created for the TerraSAR-X/TanDEM-X MPS 10,11 and constantly extended in these times. With the extension of the algorithm suite and the urge to freely combine rather small snippets to bigger algorithms (see chap.…”

The Firebird mission comprises the two spacecraft TET (launched July 22 nd 2012) and BIROS (launch foreseen for May 25 th 2016), both carrying a combined infrared-optical camera system as primary payload as well as several additional hard-and software experiments. Our Mission Planning team at the German Space Operations Center (GSOC) is responsible for generating conflict-free timelines for commanding payload and so-called background sequence operations for both spacecraft in accordance with all given spacecraft and ground-related constraints and customer requirements. Therefore, a Mission Planning system has been prepared and is continuously developed further with continuously changing space segment capabilities throughout the different project phases. The paper at hand describes the main components and their set-up, e.g. the semi-automated planning tools and the newly implemented interactive order interface for the customers. Furthermore, the decision to which extent a combined system is set up for both spacecraft as well as the advantages of being able to rely on a generic, configurable tool suite, modeling language and scheduling algorithm assembly are discussed.

“…When modeling the resource energy , the designer has to take into account that the devices that store energy (e.g., batteries) can store up to a maximum amount of charge; when the state‐of‐charge of a battery reaches 100%, energy in excess will be lost. Typically, satellite MPS encompass resource models to represent power, energy and memory (data storage) (e.g., Refs. , , , , , , ). Some missions have been seen to include complex models to represent thermal or attitude as a resource.…”

While monolithic satellite missions still pose significant advantages in terms of accuracy and operations, novel distributed architectures are promising improved flexibility, responsiveness and adaptability to structural and functional changes. Large satellite swarms, opportunistic satellite networks or heterogeneous constellations hybridizing small-spacecraft nodes with high-performance satellites are becoming feasible and advantageous alternatives requiring the adoption of new operation paradigms that enhance their autonomy. While autonomy is a notion that is gaining acceptance in monolithic satellite missions, it can also be deemed an integral characteristic in Distributed Satellite Systems. In this context, this paper focuses on the motivations for system-level autonomy in DSS and justifies its need as an enabler of system qualities.Autonomy is also presented as a necessary feature to bring new distributed Earth observation functions (which require coordination and collaboration mechanisms) and to allow for novel structural functions (e.g. opportunistic coalitions, exchange of resources or in-orbit data services).Mission Planning and Scheduling frameworks (MPS) are then presented as a key component to * Corresponding author.

An exhaustive knowledge classification explores the design aspects of MPS for DSS, and conceptually groups them into: components and organizational paradigms; problem modeling and representation; optimization techniques and metaheuristics; execution and runtime characteristics; and the notions of tasks, resources and constraints. This paper concludes by proposing future strands of work devoted to study the tradeoffs of autonomy in large-scale, highly dynamic and heterogeneous networks through frameworks that consider some of the limitations of small spacecraft technologies.
