On 4 October 2023 the FyCUS 23 pseudosatellite flew from the León aerodrome in the gondola of a B2Space stratospheric balloon and reached an altitude of 19 km.
Students built the vehicle, avionics, sensors, software and a ground station with a two-motor automatic tracking antenna, partly 3D printed, in about six months. The experimental payload can take images or make measurements, and the platform can serve as a test bed for companies, for example for agricultural mapping or sensor testing.
