CASTeC for constellation monitoring2023-11-07T14:27:54+01:00
A complete tool to automate constellation monitoring from early identification of anomalies in the satellites to fault isolation. CASTeC supports Satellite Controllers in the identification of critical operative conditions affecting service performance and mitigation strategies definition.
As of today, the increasingly high number of flying satellites will make impracticable for Satellite Controllers (SCs) to monitor effectively the health status of satellites, especially in large constellations. Therefore, an emerging need for automation in the identification of critical operative conditions is shared by the operators, along with the need of discovering additional knowledge exploting the telemetry data. CASTeC is the right solution for addressing these needs.
CASTeC (Context Aware Spacecraft Telemetry Checking) is a software tool improving constellations monitoring and diagnostics, performing:
Automatic identification of anomalous telemetries and relevant events that require investigation by SCs.
Early detection of anomalies in the behaviour of the satellites/constellation.
Automatic identification of correlated telemetries and events.
CASTeC providespredictive alertson the status of the satellites constellations, based on a detailed analysis of each single telemetry of the constellation
CASTeC identifiesrelevant eventsfrom the degree on anomaly detected
CASTeC supportsevents troubleshootingby guiding the SC in the identification of potential cause-effect relations among events.
Ease of deployment
CASTeC is a software module that can beeasily interfaced with different ground segment operations platforms.
No need for experts’ knowledge
The implemented algorithmsdo not need experts’ knowledgeon Artificial Intelligence to be configured, but only limited information and knowledge to define the relevant operative conditions of the satellites.
CASTeC characterises the expected behaviour of satellites based on an innovative method developed by SATE, namedFETCH(FEaTure CHeckability)
FETCH extracts the features of the raw telemetries time series that are “checkable” in a specific context, thereby characterising their expected behaviour
Automatic definition of checks to be applied to telemetries that are “parameter-specific” and “context-specific”
The advantage of FETCH with respect to a conventional AI is that it is fully interpretable, thus the reasons for the anomalies identified can be explained and understood by SCs.
CASTeC is a software module that can be easily interfaced with Ground Segment operations platforms.
CASTeC is delivered as a service with different service options. It is provided on cloud or, upon request, on customer’s premises.
The web-based Human Machine Interface implementation allows the installation of CASTeC on a shared (or external) machine and the investigation of the telemetry from any different location, through a web browser.
CASTeC can be used as standalone tool or integrated with other end users’ tools, through specific APIs, according to their needs.
