An integrated CNS solution for low-altitude aircraft
The ANTENNAE project is developing an innovative integrated CNS solution for aircraft operating at low altitude The ANTENNAE project explores the applicability of 3GPP 5G and next-generation hybrid terrestrial and non-terrestrial networks for providing Communication, Navigation, and Surveillance (CNS) services to aircraft operating at low altitude. The ANTENNAE project is exploring a 3GPP-compliant integrated CNS solution for Innovative Air Mobility (IAM), including piloted and U-space operations at low altitude. The solution will support safe low-altitude air traffic by providing reliable, affordable communication, navigation, and surveillance services to ensure strict adherence to flight paths, real-time traffic separation, and robust airspace boundary protection. Why legacy CNS is not enough for low-altitude aviation CNS is designed to provide three separate services: “C” – Communication, “N” – Navigation, and “S” – Surveillance. However, all three services rely on one common thing: wireless network infrastructure and its coverage. We need radio signals for the timely exchange of information between aircraft, between aircraft and the ground, and sometimes between ground systems. Global Navigation Satellite System (GNSS) signals help aircraft safely navigate …
