In the context of spaceflight, a satellite is an artificial object which has been intentionally placed into orbit. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon.
In the maritime context, "Satellite" refers to a variety of satellite-based technologies and systems that are used to improve communication, navigation, and safety at sea. Here are some examples:
Global Positioning System (GPS): GPS is a satellite-based navigation system that is widely used in the maritime industry for accurate positioning and navigation.
Automatic Identification System (AIS): AIS is a system that uses satellites to track the location, speed, and other information about ships in real-time. This information is used to improve navigation safety and to prevent collisions at sea.
FleetBroadband: FleetBroadband is a high-speed satellite-based communication system that allows ships to stay connected to the internet and to communicate with the shore while at sea.
Weather Forecasting: Satellite data is used to provide weather forecasting and oceanographic information to ships at sea, which can help them avoid dangerous weather conditions.
Other similar things to "Satellite" in the maritime context might include:
- Radar: Radar is a technology that uses radio waves to detect the location, speed, and direction of objects, including ships and other vessels.
- Sonar: Sonar is a technology that uses sound waves to detect the location, speed, and depth of objects in the water, including fish and other marine life.
- EPIRB: An Emergency Position Indicating Radio Beacon (EPIRB) is a distress beacon that uses satellite technology to alert search and rescue authorities in the event of an emergency.
- Navtex: Navtex is a system that uses radio waves to broadcast weather forecasts, navigational warnings, and other important information to ships at sea.
