Description
The objective of the activity is to develop and validate resource management algorithms for hybrid satellite systems (i.e. systems with spacecraft in both GSO and NGSO orbits) and fixed user terminals that can connect to multiple spacecraft simultaneously using active antennas. This will allow the most efficient allocation of resources across system assets. The algorithms will be validated in a software testbed.
Targeted Improvements: Enabling global management of resources across hybrid satellite communication systems not existing today.
Description:
With the emergence of NGSO constellations, several operators are or will shortly be operating several GSO and NGSO satcom systems simultaneously. Nowadays, the different systems operate independently and the user terminalscan connect only to one. However, the progress in active antennas augur multi-beam user terminals capable of connecting to multiple GSO and NGSO systems at the same time. This would enable a satellite network to work as a system-of-systems with GSO and NGSO components. Such system is also known as a hybrid satellite system.
The Radio Resource Management (RRM) is a critical component of any satellite network that decides how it will deliver the different services to the different users. This becomes even more critical for hybrid networks where each service may be delivered by different means. For example, a User Terminal could download a software update broadcasted from a certain GSO satellite, while being simultaneously connected to an NGSO satellite for a low latency service and to a different GSO satellite for a file transfer. In this scenario, the RRM is crucial for the efficient and effective use of the system resources, balancing the load across the system components and maximising the overall throughput. However, an RRM capable of managing resources across GSO and NGSO components of a hybrid system does not exist.
The activity will therefore develop and validate the RRM of a hybrid satcom system with fixed user terminals. The algorithms will decide which component or components (GSO or NGSO) will provide each of the services for each user according to their load, the required Quality of Service (QoS) and the available resources, and will configure such components accordingly. The RRM algorithms will be implemented in software and their capabilities will be demonstrated in a software emulator.
