A Land Earth Station (LES) is a ground-based facility that serves as a crucial link between satellites and terrestrial communication networks. In the Inmarsat system, LES receives signals from Mobile Earth Stations (MES) onboard ships and aircraft, processes them, and forwards them to the appropriate recipient. LES facilities handle various types of maritime communication, including distress alerts, navigational updates, weather warnings, and commercial messaging. These stations ensure that communication between vessels and land-based authorities remains seamless. LES also plays a role in network management, assisting Network Control Stations (NCS) in maintaining connectivity and troubleshooting technical issues. The efficiency of an LES directly impacts the reliability of satellite communication, making it an essential part of global maritime operations. Many Inmarsat services, such as Inmarsat C and Enhanced Group Call (EGC), rely on LES to transmit messages. Regular maintenance and upgrades of LES infrastructure help ensure stable and secure maritime communication. Without LES, ships would face significant communication challenges, especially in remote oceanic areas. This system remains an indispensable part of maritime safety, supporting seamless global communication for commercial and emergency applications.
