Remote Sensing Platforms and Its types
The document discusses various remote sensing platforms including air-based and space-based systems, highlighting their importance in data acquisition for applications like meteorology and resource mapping. It categorizes air-based platforms into free and tethered balloons, aircraft, helicopters, drones, and sailplanes, while detailing their operational parameters. Space-based platforms are classified into geostationary and sun-synchronous satellites, with descriptions of their orbits, purposes, and resolution capabilities.

Satellites – Usein Natural resource mapping, meteorological and communication applications Free flying orbiting vehicles whose motion is governed by gravity and atmosphere based Kepler’s Law Entire earth or designated portion can be suitably covered at specified intervals Least affected by disturbance in atmosphere and hence their orbits can be properly defined Also helpful in viewing extraterrestrial bodies Types (i) Geostationary Satellites (ii) Sun Synchronous Satellites
- 18. Geostationary Satellites Also knownas Earth Synchronous Satellites and the orbit in which these satellites move is called geosynchronous or geostationary satellite Placed at a distance of 36,000km above the equator At this altitude the orbital speed of the satellite is the same as that of the Earth’s rotation speed. Satellite cover the same area continuously over they are flying and information transmission is rapid Spatial resolution is poor (1 km) Used for Weather forecasting and Communication Purposes

Sun Synchronous Satellites ProvideGlobal coverage with high resolution Used for applications in resource surveys and monitoring Also called natural resource or polar satellites Move in low earth orbit at 800-1000km altitude over or near the north and south poles. The orbit is known as polar or sun synchronous orbit, coinciding with the plane of the sun. Normally passes a particular place at the same local time after a regular interval of time, providing repetitive coverage of the place.
