Satellite communication is the process of transmitting and receiving information using artificial satellites orbiting the Earth. It allows for long-distance communication across vast geographical areas, overcoming limitations of terrestrial networks. Key Characteristics / Core Concepts Geostationary Orbit (GEO): Satellites positioned above the equator, appearing stationary from Earth. Medium Earth Orbit (MEO): Satellites orbiting at a … Read more
Navigation is the process of finding your way from one place to another. It involves planning a route and then following that route to reach a destination. Key Characteristics / Core Concepts Route Planning: Determining the optimal path to a destination, considering factors like distance, time, and obstacles. Wayfinding: Using cues and signs to follow … Read more
Marine navigation is the process of planning and executing a safe and efficient voyage for a vessel on water. It involves determining the vessel’s position, planning a route, and monitoring progress to reach a destination. Key Characteristics / Core Concepts Position Fixing: Determining a vessel’s precise location using various tools and techniques. Route Planning: Choosing … Read more
Geodesy is the science of accurately measuring and representing the Earth’s shape, size, and gravity field. It’s essentially the science of precisely mapping the Earth. Key Characteristics / Core Concepts Earth’s Shape: Geodesy deals with the Earth’s not-quite-perfect sphere shape, accounting for its oblateness (flattening at the poles). Gravity Field: Geodesy measures variations in Earth’s … Read more
Geomatics is the science and technology of gathering, analyzing, and managing spatial data (data related to location). It combines aspects of surveying, mapping, geographic information systems (GIS), and remote sensing to create a comprehensive understanding of the Earth’s surface and its features. Key Characteristics / Core Concepts Utilizes various technologies like GPS, LiDAR, and drones. … Read more
