Dr Peter Christopher - University of Nottingham

Research Fellowships 2024

My researchDr Peter Christopher’s work at the University of Nottingham is on developing portable, low-cost modules for satellite-ground laser communications (SGLCs). The Royal Academy of Engineering’s Research Fellowship supported work will enable ultra-fast internet connections in locations including disaster zones, remote installations, ships, aircraft, and future deep-space missions to the moon and beyond. It also has the potential to provide internet access for the 2.9 billion people remaining without reliable internet access and help level the global playing field in education, innovation, and research.

SGLCs are on the cusp of transforming the space and telecoms industries as they allow for data links more than 100 times faster than current satellite radio technologies, including those used by Starlink and OneWeb. Compared to satellite radio, SGLCs use less power; do not interfere with other transmissions; do not use valuable radio spectrum; do not require complex international legislation; have lower hardware costs; produce fewer carbon emissions; and are point-to-point, increasing security. 

Critically, they will enable ultra-high-speed telecommunications anywhere in the world at the expense of only the initial satellite constellation and local ground station, bringing universal internet access closer to reality.

Digital connectivity and internet access have been identified as major factors in reducing global income disparity and gender inequality while promoting education and social mobility. Infrastructure costs are perhaps the greatest challenge to universal internet coverage and Dr Christopher’s research aims to help develop the technology necessary to make cheap, portable ultra-fast internet available globally. This will support decentralisation of industry and commerce by reducing reliance on expensive fibre infrastructure and co-localisation. It will also help developing regions and economies to compete in data-intensive fields more easily.

In addition to connecting remote communities, SGLCs also present a crisis response opportunity, allowing for rapid deployment of terminals to disaster regions.
