The smarter space missions become, the more ‘housekeeping’ data they generate. In theory, this is good news, enabling greater oversight for ground controllers. But with communication links limited in capacity, floods of this telemetry data risk crowding out payload data – the scientifically or commercially valuable information the mission is there to provide. A new ESA-patented data compression method, soon available for use by all missions, helps prevent this from happening.
