MeluXina To Improve Satellite Performance

Research partners SnT and SES have received access to supercomputer MeluXina to optimise satellite performance.

Chosen among several national and international applicants for early access to MeluXina, the SnT-SES project was recognised as having a high potential impact on society, science and the economy. This is a timely announcement for Luxembourg-based SES, which is beginning to operate its fully-digital satellites.

With space innovation becoming increasingly important for the economy, it comes as no surprise that one of the selected MeluXina projects is related to satellite performance optimisation.

According to the press release, the resource allocation for satellite communications project will focus on “modelling and optimising performance and radio spectrum usage for broadband satellite communications systems.”

As satellites continue to deliver a wealth of content and connectivity services to millions of users simultaneously, “resources such as spectrum and transmission power need to be continuously allocated in the most optimal way to maximise the system performance,” the press release continues.

“Groundbreaking Advances”

In collaboration with one of its industry partners, SES has recently made “groundbreaking advances” for large-scale optimisation across its new satellites. Access to MeluXina couldn’t come at a better time.

“In order to optimise the performance of our innovative, next-generation satellites, we have to use software-based systems with complex algorithms, and run hundreds of tests before our new satellite systems are operational,” explains Ruy Pinto, CTO of SES.

Together with SES, SnT has made great use of MeluXina’s outsized computational powers to push forward Luxembourgish spacetech.

“MeluXina’s computational power enabled the project team to scale up the complexity of their work, investigating optimisation scenarios that would not be realistic to consider with normal computers,” concludes SnT director Professor Björn Ottersten
