Drones to keep tabs on light pollution
Astronomers at Nottingham Trent University have developed a light, low cost system, deployable on a drone, that could help everyone monitor and control light pollution.
Astronomers at Nottingham Trent University have developed a light, low-cost system, deployable on a drone, that could help everyone monitor and control light pollution. The team, led by undergraduate student Ashley Fuller, is presenting its work at the National Astronomy Meeting at the University of Nottingham.
Excessive light is a pollutant in its own right, as is the energy, and carbon footprint, needed to generate it. The cultural and scientific impact is very visible, and recent studies confirm that light pollution prevents a third of the global population from seeing the Milky Way.
Dark skies are preserved in some designated areas, with parks, islands and other reserves offering places in the UK and around the world where the night sky is still relatively pristine. All these places, though, need continuous monitoring.
The Nottingham Trent University team is presenting a new mount and operational platform carrying a Sky Quality Monitoring device (SQM), which operates autonomously and can be used to map the sky without any specialist training. Ashley worked on its development for a final year project, with Dr Daniel Brown and Dr Rob Morris, of the University's School of Science and Technology.
The night sky is a vital part of our heritage, and one we should strive to protect
The new monitoring system is based on a microcontroller and standard servo motors, and the data it gathers is stored on an SD card. Ashley and the team see it being used by, for example, national park rangers carrying out their work on site. Crucially, it is light enough to be mounted on a drone, which will take the device to inaccessible areas, making it a lot easier to create a comprehensive map.
Ashley said: “The night sky is a vital part of our heritage, and one we should strive to protect. With a drone-mounted autonomous system, we can quickly gather the evidence we need to show where the problem is worst, and on a more positive note, find out where people can see the best views of the stars.”
The team would like to see the new light pollution monitoring system, with its straightforward and low-cost design, being taken up by schools and colleges. As an astronomy project, it could inspire young people to develop the skills in IT, electronics and physics that are needed for sustainability and that are so much in demand in the wider economy.
Notes for editors
The RAS National Astronomy Meeting 2016 (NAM 2016) takes place this year at the University of Nottingham from 27 June to 1 July. NAM 2016 brings together more than 500 space scientists and astronomers to discuss the latest research in their respective fields. The conference is principally sponsored by the Royal Astronomical Society, the Science and Technology Facilities Council and the University of Nottingham.

The Royal Astronomical Society (RAS), founded in 1820, encourages and promotes the study of astronomy, solar-system science, geophysics and closely related branches of science. The RAS organizes scientific meetings, publishes international research and review journals, recognises outstanding achievements with the award of medals and prizes, maintains an extensive library, supports education through grants and outreach activities, and represents UK astronomy nationally and internationally. Its more than 4,000 members (Fellows), a third based overseas, include scientific researchers in universities, observatories and laboratories as well as historians of astronomy and others.
Nottingham Trent University’s five-year strategic plan, Creating the University of the Future , has five main ambitions: Creating Opportunity, Valuing Ideas, Enriching Society, Connecting Globally, and Empowering People.
The Queen's Anniversary Prize for Higher and Further Education was awarded to Nottingham Trent University in November 2015. It is the highest national honour for a UK university and recognises the institution’s world-class research. Pioneering projects to improve weapons and explosives detection in luggage, enable safer production of powdered infant formula, and to combat food fraud, led to the prestigious award.
The University of Nottingham has 43,000 students and is ‘the nearest Britain has to a truly global university, with a “distinct” approach to internationalisation, which rests on those full-scale campuses in China and Malaysia, as well as a large presence in its home city.’ (Times Good University Guide 2016). It is also one of the most popular universities in the UK among graduate employers and the winner of ‘Outstanding Support for Early Career Researchers’ at the Times Higher Education Awards 2015. It is ranked in the world’s top 75 by the QS World University Rankings 2015/16, and 8th in the UK by research power according to the Research Excellence Framework 2014. It has been voted the world’s greenest campus for four years running, according to Greenmetrics Ranking of World Universities.
Impact: The Nottingham Campaign, its biggest-ever fundraising campaign, is delivering the University’s vision to change lives, tackle global issues and shape the future.
The Science and Technology Facilities Council (STFC) is keeping the UK at the forefront of international science and has a broad science portfolio and works with the academic and industrial communities to share its expertise in materials science, space and ground-based astronomy technologies, laser science, microelectronics, wafer scale manufacturing, particle and nuclear physics, alternative energy production, radio communications and radar. STFC's Astronomy and Space Science programme provides support for a wide range of facilities, research groups and individuals in order to investigate some of the highest priority questions in astrophysics, cosmology and solar system science. STFC's astronomy and space science programme is delivered through grant funding for research activities, and also through support of technical activities at STFC's UK Astronomy Technology Centre and RAL Space at the Rutherford Appleton Laboratory. STFC also supports UK astronomy through the international European Southern Observatory. Follow STFC on Twitter via @stfc_matters
