The UK space sector had an annual growth rate of 3.3% from 2014 to 2017 and the government has expressed ambitions to grow the sector to 10% of the global space economy by 2030. Participation in EU space programmes has provided UK based organisations with data, work contracts and funding. This POSTbrief focuses on three of the key EU space programmes that the UK has participated in.

Galileo will provide navigation, timing and positioning information for a wide range of applications, including the emergency services and aviation. The UK has received around 20% of the work contracts for the development of this system. The Government are not pursuing further involvement after the transition period because the EU will not allow them continued knowledge of the security sensitive parts of the system. Instead, the Government has proposed the development of a sovereign UK navigation system.

Copernicus is the EU’s Earth observation system which provides data and services for tackling climate change and monitoring agriculture, amongst many other things. The UK’s involvement in this programme following the transition period is uncertain at the time of writing and will depend on the outcome of negotiations. UK based academia and industry stakeholders are strongly in favour of continued UK participation.

EUSST is a programme which monitors space debris and active satellites orbiting the Earth to protect satellites from damaging collisions. It is likely that UK participation in this programme will cease following the transition period but access to services provided by the programme may be negotiated.

This POSTbrief provides a technical overview of each of Galileo, Copernicus and EUSST and the involvement of the UK in these programmes to date. The future of each of the programmes is discussed in the context of Brexit, as well as in light of the impact of emerging technologies and requirements.

  • Genome edited animals

    Genome editing, also known as gene editing, encompasses a broad range of techniques that allows targeted changes in the DNA of animals (and plants). The Genetic Technology (Precision Breeding) Bill 2022 -2023, due for Second Reading in the House of Lords on 21 November 2022, intends to change the regulatory definition of certain genome-edited animals.

  • Automation in military operations

    Advances in robotics and digital technologies, such as artificial intelligence (AI), are enabling greater levels of automation across many sectors, including defence. The UK Government expects automation to be crucial to maintain military advantage in the future. In June 2022, the Ministry of Defence published its Defence AI Strategy, which sets out how it plans to adopt and exploit AI; automation was cited as a key application. This POSTnote discusses current and future applications of automation and AI, their impact on militaries and global stability, and the challenges around their development and implementation.
