The UK has launched its Titania military satellite to strengthen its ability to monitor activity on Earth, while preparing trials of a separate sensor network to detect potential threats in orbit.
The two initiatives form part of more than 3 billion pounds ($4 billion) allocated to defense space capabilities over the next four years.
UK Space Command will operate the spacecraft under the ISTARI program, which seeks to develop satellites and support ground infrastructure to collect intelligence from space.
The spacecraft was designed and built in Hampshire through a partnership between the Defence Science and Technology Laboratory and BAE Systems under a 9.5 million pounds ($12.8 million) contract.
Weighing 100 kilograms (220 pounds), Titania circles Earth every 90 minutes at a speed of around 27,000 kilometers (16,777 miles) per hour. It joins Tyche as part of the UK’s growing military surveillance constellation.
Additional satellites are planned through separate projects involving Surrey Satellite Technology Limited and Airbus Defence and Space.
UK Tests Sensors to Monitor Threats in Orbit
Alongside Titania’s deployment, London is establishing Project Inaros to test ground-based sensors that could help detect unusual or potentially hostile activity near British satellites.
The trial will place three sensors at locations in the UK, Australia, and Cyprus.
British-Australian company Optera developed the technology in partnership with the National Security Strategic Investment Fund.
Known as neuromorphic sensors, the devices detect changes in light using an approach inspired by biological vision. The trials will assess whether they can track movement in space and contribute to a future early warning system.
Data gathered through Inaros will support UK Space Command units responsible for space operations, threat warning, and satellite protection.
The goal is to help safeguard satellites that provide critical services, including navigation, communications, and missile warning.
