N3SS Mission

The N3SS mission (Nanosat 3U for Spectrum Surveillance) is a pioneering initiative by U-Space, aimed at enhancing the monitoring and management of the radio frequency (RF) spectrum from space. Launched in October 2023, this CubeSat-based demonstrator is specifically designed to detect and localize sources of RF interferences. The mission seeks to address the growing need for secure and interference-free satellite communication systems. Positioned in a 564 km low Earth orbit, N3SS serves as a critical step in safeguarding RF-dependent infrastructures, contributing to global communication resilience and security.

Client's Needs

For the N3SS mission (3U Nanosatellite for Spectrum Surveillance), U-Space aimed to create a technological demonstrator capable of detecting and locating interferences in civilian communication systems, especially those relying on satellite navigation like GPS. The satellite needed to operate in the L (1–2 GHz) and S (2–4 GHz) bands, which are critical for applications such as LTE networks, radar systems, and military communications. The mission demanded compact, high-performance antennas capable of functioning in the challenging conditions of space while meeting the size and weight constraints of nanosatellites.

Why Anywaves

U-Space selected Anywaves due to its recognized expertise in designing and manufacturing high-performance miniaturized antennas for nanosatellites. Anywaves’ antennas, designed to withstand the harsh environment of space, met the mission’s requirements for compactness and efficiency. Additionally, Anywaves’ ability to provide customized solutions allowed seamless integration of the antennas into the N3SS 3U CubeSat platform.
