Spacecraft name	Delfi-Twins
Type	PocketQube
Units or mass	PocketQube 3p
Organization	Delft University of Technology
Institution	University
Entity type	Academic / Education
Country	Netherlands
Oneliner	Demonstrate formation flying and advanced space traffic management capabilities
Description	The satellites will be initially deployed in a docked configuration and separated on command, allowing ground-based optical and radio networks to track the separation event in real time. The formation will be established using deployable wings to control drag, maintaining a baseline distance of approximately 100 km between the satellite Equipped with on-board GNSS receivers, the mission aims to achieve sub-meter-level orbit knowledge, which will be validated by ground-based laser reflector tracking. Additional payloads include a miniaturized radiation detector and other novel sensors, all developed in-house by students and researchers at TU Delft.
