Geostationary Orbit (GEO)
In the maritime context, a Geostationary Orbit (GEO) is a circular orbit approximately 35,786 kilometers (22,236 miles) above Earth's equator and following the direction of Earth's rotation. An object in such an orbit has an orbital period equal to the Earth's rotational period, known as a sidereal day, and thus appears motionless, at a fixed position in the sky, to ground observers. This makes GEO satellites ideal for maritime communication, weather monitoring, and navigation. They provide a constant line of sight to a specific geographical area, enabling continuous data transmission and reception. In maritime operations, GEO satellites are used for high-speed data transmission, real-time weather updates, and precise navigation. They play a crucial role in enhancing the safety, efficiency, and effectiveness of maritime operations. However, due to their high altitude, there can be a slight delay in signal transmission, which needs to be considered in time-critical maritime operations.
