Royal Aeronautical Society Lecture: Stop Counting Satellites - from spacecraft to outcomes

This Royal Aeronautical Society lecture explores how space underpins modern life in ways that are often invisible, from communications and navigation to timing systems, environmental intelligence and public safety. Rather than focusing only on the number of satellites launched, the talk examines the outcomes that space systems are meant to deliver and asks how those outcomes can be sustained when something goes wrong.

The lecture looks at space as an interconnected system made up of orbital assets, ground systems, software, data, infrastructure, institutions and people. Through examples including resilient timing, collective satellite behaviour, offshore observation and lifeboat navigation, it considers shared dependencies, recovery when protection fails, and how research becomes enduring operational capability.

It also introduces the idea of Assured Space as a way of judging whether a space-enabled service can continue despite disruption.
