Description: 

Smallsat DTN is an OPS-SAT experiment awarded funding trough ESA’s OSIP, OPS-SAT campaign. The aim of the project is to investigate the benefits of CFDP and Bundle Protocol for satellite operations and their possible applications in the optical communications links, of the future ESA mission of OPS-SAT 2. The Flight Campaign of the project completed in a three-day span, successfully demonstrating the implementation of a LEO DTN network, spacecraft remote control and configuration over Bundle Protocol and CFDP imagery data distribution over multiple passes from the ground segment. Finally, benefits of DTN networking on optical links, in cloud blockage, complete miss of a pass and Variable Data Rates scenarios (relevant to OPS-SAT 2 future ESA mission) were also demonstrated.
