Wireless power beaming will provide auxiliary power to increase the baseline efficiency of small satellites in lower Earth orbit
The University of Surrey and Space Power are tackling the problem of powering satellites in Low Earth Orbit (LEO) during their eclipse period when they cannot see the sun. By collaborating on a space infrastructure project, the joint team will develop new technology which uses lasers to beam solar power from satellites under solar illumination to small satellites orbiting closer to Earth during eclipse. The wireless, laser-based power beaming prototype will be the first developed outside of governmental organisations and is aiming for commercialisation by 2025.
Wireless power beaming is a critical and disruptive technology for space infrastructure and will provide auxiliary power to increase the baseline efficiency of small satellites in LEO. The technical side of the project will use the highly specialised laser laboratories and optical systems developed at the University of Surrey’s Department of Physics and Advanced Technology Institute, which are world leaders in the development and implementation of laser and photovoltaic-based technologies. The first Space Power product will be designed as a plug-and-play system for satellite manufacturers to include in their offering to their LEO constellation customers.
Without new power technologies like this, which will enable small satellites to function all the time, more satellites are needed, with the resultant costs, launch emissions and contribution to space debris. As humanity finds more ambitious and useful tasks for small satellites, the problem grows.
