Spacecraft data:

Description:

• SNUSAT 1 is a 2U QB50-KR02, from Seoul National University.
• SNUSAT 1b is a 2U QB50-KR03, from Seoul National University
• SNUSAT-1 / 1b (Seoul National University Satellite 1), is a South Korean 2U-CubeSat designed by the Seoul National University participating in the QB50 project. It carries the Flux-Φ-Probe Experiment (FIPEX) as the primary payload for the QB50 project, measuring lower thermosphere constituents at altitudes starting from 350 km and down as the orbit decays due to atmospheric drag. The secondary mission is validation of fault-detection, isolation and recovery algorithm developed by Seoul National Unit and imaging space environment.
