On Wednesday 28 August, the Queen Elizabeth Prize for Engineering exhibited a new, interactive activity at the Science Museum Lates in London. Visitors had the chance to take part in a GPS-inspired scavenger hunt around the museum, using engineering skills to navigate to hidden checkpoints and win prizes.
The key to finding the checkpoints was trilateration – the process used by GPS satellites to pinpoint locations. When finding a location on a sat nav or Google Maps, satellites send out signals to the receiving device, e.g. a phone, on Earth. If you know what time a signal left a satellite and reached the phone, the distance from the satellite to the phone can be calculated. Data from four satellites is combined to find the location of the phone. Imagine a spherical radius around each satellite – the receiver location is where the four spheres intersect.
QEPrize winners Hugo Fruehauf and Bradford Parkinson recently appeared on BBC Inside Science to discuss their incredible, world-changing innovation: the Global Positioning System. Both engineers made a crucial contribution to the development of the revolutionary system, which opened up navigation to people all around the world. In February 2019, Bradford and Hugo, along with Richard Schwartz and James Spilker, Jr, were awarded the Queen Elizabeth Prize for Engineering for their pivotal roles in creating GPS.
The third episode of the Create the Future podcast is out now! Joining us this month to discuss what our future cities might look like are Larissa Suzuki, senior product manager for automatic machine learning at ORACLE, and honorary associate professor at UCL; and Andrew Comer, director of the cities business unit at BuroHappold Engineering.
In this month’s episode, Smart Cities: all hype or a platform for change?, we look back on the technological and economic successes of the 2012 Olympic Games; debate the implications of using people’s data to improve city infrastructure; and highlight the need to ensure that smart city technology is developed to be inclusive, not a commodity.

People often associate engineering with bridges and buildings, but, in fact, engineering is all around us. From sustainable coffee cups and people-powered pavements to new medical technologies, quantum computers, and the internet of things, there is a huge range of engineering wonders that we encounter in our day-to-day. The sheer variety of these innovations never fails to amaze me, but two of my favourites are an incredible paint called Inesfly, and a videogame called MalariaSpot. Both of these – while entirely unknown to most – save thousands of lives from insect-borne diseases every year.
The future of the human race relies, in part, on water sustainability. Malthusian theorists predict water will become the most valuable commodity traded and accessible to only the highest bidders; while this might sound farfetched and dystopian, consider that freshwater scarcity affects approximately 4 billion people globally, according to the United Nations World Water Development Report 2019.
A prevalent misconception is that water shortage only truly affects resource-poor parts of the world. When you think of a water shortage in the UK, for example, you picture hosepipe bans affecting the growth of people’s lawns and flowerbeds. While this might be annoying for some, it certainly doesn’t compare with other environmental issues such as the amount of plastic in our oceans and the rising temperature of the planet.
In March 2019, water scarcity hit UK headlines when Sir James Bevan, chief executive of the Environment Agency, warned that England will run short within 25 years. There are similar estimates elsewhere in the world; according to The Guardian, 50% of the world will be living in water-stressed areas by 2025.
In conversation with Keshini Navaratnam, Anuradha TK, Geosat Programme Director at the Indian Space Research Organisation (ISRO), discusses a breadth of topics from the key considerations for communications in space and the interplay between form and function in satellite design, to the excitement for India’s first crewed space flight in 2022, the role of AI in space exploration, and the inspiration behind her journey into engineering.

UNESCO’s recent decision that 4 March will henceforth be celebrated as World Engineering Day for Sustainable Development was a significant moment for both early-career and established engineers alike. Starting in 2020, the annual celebration will present a global opportunity to celebrate the profession and encourage the next generation of engineers to solve the challenges of the future. Our previous article on the announcement can be found here.
We sat down with WFEO President Dr Marlene Kanga, who led the initiative, to hear her response to the announcement:
“Engineers have a hand in designing, creating, or modifying nearly everything we touch, wear, eat, see, and hear in our daily lives.”– American Society of Engineering Education
