   Sammanfattning : Many satellites in LEO use a GNSS-based navigation system, taking advantage of the GNSS constellations in MEO to enhance navigation capabilities. The thesis work focused on developing the software enabling GNSS-based navigation for Hemeria's future small satellites operating in LEO. LÄS MER

3. 2. Analysing space dependencies - Methods and factors for method development

   Master-uppsats, Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

   Författare :Theodor de Sousa; [2022]
   Nyckelord :Vital societal functions; critical infrastructure; interdependency; dependency analysis; space services; space infrastructure; GNSS; PNT; ICT; method development; Technology and Engineering;

   Sammanfattning : Vital societal functions and critical infrastructure rely to an increasing extent on services from space, such as navigation and positioning systems, timekeeping, and communications. However, understanding of space service dependencies is low among practitioners and society at large, with research on societal space dependency being limited as well. LÄS MER
