Interactive map will show real-time pollution levels in London

21 July 2016: Inmarsat satellite connectivity will help build the world’s first detailed air pollution map, covering Greater London.

Internet of Things (IoT) platform company Drayson Technologies is partnering with Inmarsat and courier company Gophr to capture real-time data on pollution levels in the capital. A recent report from the Royal College of Physicians (RCP) and the Royal College of Paediatrics and Child Health (RCPCH) estimated that around 40,000 deaths a year in the UK are linked to air pollution.


Fifty bicycle couriers will be equipped with CleanSpace Tags – portable air pollution smart sensors created by Drayson Technologies – and LoRa™ long range trackers supplied by Inmarsat, enabling carbon monoxide levels to be collected on the move, at breathing height.

View exposure

The data will feed into the Air Map, an interactive map that will show the pollution levels at the location of each courier, in real time. With the couriers predicted to travel over 17,000 miles across London each month, the amount of indoor and outdoor air pollution data collected will be on a scale that has never been achieved before. The collected data is anonymised and fed into the CleanSpace mobile application allowing users to view their exposure to air pollution.

The LoRa trackers will track the location of the Gophr couriers via satellite without having to use mobile location based services which drain battery life. This provides more accurate readings on the move, with the need for fewer access points to cover the whole area of a city.

The CleanSpace Tag is the first product to be powered by Freevolt™, a revolutionary technology launched by Drayson Technologies that harvests and recycles wasted wireless signals to power low-energy devices so their batteries never need changing.

Addressing issue

Gophr and Inmarsat are the first partners announced in Drayson Technologies’ plan to create the world’s most advanced air pollution map of a city. Further organisations, groups and individuals will be equipped with CleanSpace Tags in the coming weeks and months in order to collect data, gather insights and help address the issue of air pollution in the capital.

Greg Ewert, President for Enterprise Markets, Inmarsat said: “Air pollution is a global problem, contributing to about 40,000 early deaths a year in the UK alone. Creating an accurate air pollution map at breathing height will contribute to the better understanding of how to combat this issue and improve air quality in London. This is the first example of a public LoRa network in London and we hope this partnership with Gophr and Drayson will be the first of many city air pollution projects.”

Lord Paul Drayson, Chairman and CEO, Drayson Technologies, said: “The CleanSpace network aims to provide the world’s most advanced air pollution map using thousands of personal sensors powered by Freevolt. This partnership brings together the combined expertise and commitment of Drayson Technologies, Gophr and Inmarsat so that people in London can see the air they breathe and help to create not just a smart city, but a smarter society.”
