N3SS
N3SS [CNES]
N3SS (Nanosat 3U pour la Surveillance du Spectre) is an in-orbit demonstrator developed to perform planetary surveillance of the civilian radiofrequency spectrum in the L and S bands and to analyze sources of jamming. Its objective is also to provide in-orbit validation of the very small, very low-mass satellite design developed using the “design to cost” approach.
The flight segment is based on a 3U CubeSat with strong heritage from the EyeSat platform. It is equipped with a miniaturized prototype payload instrument. CNES is responsible for the system and satellite development and also in charge of the in-flight operations of the satellite. U-Space is the prime contractor for the platform development and the satellite AIT/AIV.
