Ground-Based Landing Systems enabling all-weather aircraft landings hero image
Overview

We deliver expertise in ground-based landing systems that allow aircraft to land in all-weather conditions.

SNC’s Ground-Based Landing Systems enable safe, reliable aircraft landings in all-weather conditions, including low visibility, cloud cover and low ceilings known as Instrument Meteorological Conditions (IMC). Designed for both crewed and uncrewed platforms, these systems operate under Instrument Flight Rules (IFR) using radar, differential GPS and hybrid sensing technologies.

‍

Our portfolio spans precision approach radars and instrument approach guidance to full automatically controlled landings and rollout systems that support diverse mission environments.
