Location is a key requirement when attempting to monitor and map the spread of a disease and GNSS is one of the main tools supporting this. Galileo, currently embedded in over 1.3 billion smartphones and devices worldwide, is helping to increase GNSS accuracy and availability, especially in urban areas. Since the outbreak of the coronavirus earlier this year, many apps have been developed that use GNSS location to monitor the global spread of the virus and to map outbreaks of the COVID-19 disease. GNSS-apps are also proving their usefulness by helping people to implement social distancing in queues and other public spaces.
