Satellites: Satellites are the most commonly used remote sensing platforms. These are instruments that revolve around the earth and capture data from above the atmosphere to observe land, oceans, and atmosphere.
Aircraft: Aircraft is another platform used in remote sensing that involves collecting data from the atmosphere. Aircraft are used for collecting data from specific locations, typically lower altitudes than satellites.
Drones: Drones or unmanned aerial vehicles (UAVs) are another remote sensing platform used for collecting aerial data. Drones come in various sizes, from small handheld devices to large flying machines.
Ground-Based Sensors: Ground-based sensors include various instruments like temperature sensors, rainfall sensors, weather stations, and others, which are used to collect data from the surface of the earth.
Balloons: Weather balloons are used to measure atmospheric data like temperature, pressure, and humidity at specific heights.
Ships and Boats: Ships and boats equipped with various sensors are used to collect data on the ocean, including currents, temperature, salinity, and others.
Buoys: Buoys are floating instruments that are equipped with sensors to collect oceanographic data at specific areas.
Ground Stations: Ground stations are used to receive, process, and transmit data from satellites and other remote sensing platforms.
Rockets: Rockets are also used to collect remote sensing data, especially from the upper regions of the atmosphere.
