Low Earth Orbit (LEO)
In the maritime context, Low Earth Orbit (LEO) refers to the placement of satellites at an altitude between 160 to 2,000 kilometers above the Earth's surface. These satellites are primarily used for data communication, such as GPS navigation, weather monitoring, and maritime communication. LEO satellites have a shorter communication delay compared to satellites in higher orbits due to their proximity to Earth, making them ideal for real-time communication necessary in maritime operations. They are also used for maritime surveillance, tracking ships, and monitoring sea traffic to prevent collisions and accidents. Furthermore, LEO satellites play a crucial role in distress and safety systems, such as the Global Maritime Distress and Safety System (GMDSS), which uses these satellites to relay distress signals from ships to rescue coordination centers. In summary, Low Earth Orbit (LEO) is a critical component in maritime navigation, communication, safety, and surveillance systems.
