A US military space-plane, the X-37B orbital test vehicle, is due to embark on its eighth flight into space on August 21 2025. Much of what the X-37B does in space is secret. But it serves partly as a platform for cutting-edge experiments.

One of these experiments is a potential alternative to GPS that makes use of quantum science as a tool for navigation: a quantum inertial sensor.

Satellite-based systems like GPS are ubiquitous…
