Optimisation tools have a strong heritage within space mission design, allowing higher performance and/or enabling missions that would otherwise not be possible. However due to the disparity of design and modelling tools across the different design domains, such optimisation is typically only performed at subsystem / domain level (e.g. trajectory or control optimisation). ;The integration of system-wide design information into a single digital system model, affords a new opportunity for optimisation at the system-level.

Additive Manufacturing (AM) is starting to be used for space applications. For future missions, many components could be manufactured using AM, also including primary structures or other mission-critical parts such as RF hardware. Final products such as feed components, beam forming networks, low and high power filters and RF harness can benefit from the advantages provided by AM. The overall maturity of this manufacturing technique has been increased in the last years offering a great variety of materials, processes and post-processes required to achieve the final part.

Plastic packaging is the most common packaging technology in commercial and automotive markets. The technology has evolved considerably, reducing the different failure modes initially associated with plastic packages. The apparition of Enhanced Plastic (plastic packages with added quality assurance requirements and extended testing is increasing the acceptability of these devices.

Currently two Global Navigation Satellite Systems (GNSS) are fully operational. These two systems are the US GPS and the Russian GLONASS. However, the number of available GNSS in 2020 will grow up to four operational systems and the number of available GNSS satellites will be over 120 for potential users. Each GNSS will have at least three civil frequencies and more than two types of new GNSS signals. The complexity for processing of GNSS signals will increase substantially and the aspect of Interoperability will gain on importance for all GNSS users.

Anomaly detection in time series is an active area of research in which multiple classic and machine learning algorithms were proposed. However, satellite telemetry is a special case of time series characterized by high dimensionality, missing data, and – most importantly – limited information about known anomalies. The leading approach for time series anomaly detection (TSAD) in satellite telemetry is to establish a normality model based on available nominal telemetry periods and search for significant deviations from that model in the test data.
