Paper Category: testing dual comm s-band systems colocated on the same CubeSat bus and for an intersatellite link demonstration

The ALIGN (Autonomous Laser-based Intersatellite Gigabit Network) mission comprises a pair of 6U CubeSats equipped with FOCUS (Free-space Optical Communications Unit for Space), an experimental payload demonstrating high-data-rate optical intersatellite links in Low Earth Orbit (LEO) and advanced hybrid optical/radio intersatellite communications. Each satellite implements a dual RF-link architecture: the Radio Ground-to-Satellite Link (RGSL) for…
