Geostationary satellites orbit the Earth at the equatorial plane at an altitude of approximately 35,786 kilometers, allowing them to match the Earth's rotation and remain fixed over a single longitude. This unique position makes them ideal for telecommunications, weather monitoring, and broadcasting services, as they provide consistent coverage over specific areas.

Aviation safety encompasses the measures and regulations implemented to ensure the protection of passengers, crew, and aircraft from accidents and incidents. It involves a systematic approach to risk management, emphasizing the importance of technology, human factors, and regulatory oversight to maintain and improve safety standards in the aviation industry.

Aviation Safety

Maritime navigation is the process of planning and controlling the movement of vessels from one location to another across the sea, relying on a combination of traditional techniques and modern technologies to ensure safe and efficient voyages. It involves understanding and applying principles of chart reading, celestial navigation, and electronic systems like GPS to avoid hazards and optimize routes.
