Remote Sensing Satellites And Their Uses

Remote sensors which provide a global perspective and a wealth of data about earth.

Remote sensing satellites and their uses. Remote sensing satellites e g. Remote sensing instruments are of two primary types active and passive. Nasa observes the earth and other planetary bodies via remote sensors on satellites and aircraft that detect and record reflected or emitted energy. It is important for business tourism and other important industries.

Goes12 13 14 and 15 are used to forecast and monitor weather. Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance typically from satellite or aircraft. Characterization of satellite remote sensing systems. Applications of remote sensing satellites.

In this process remote sensing technology is used to observe surface color and temperature to derive areas full of fishes. It helps in observing the flow of ocean currents and circulation. Remote sensing is the acquiring of information from a distance. Active sensors provide their own source of energy to illuminate the objects they observe an active sensor emits radiation in the direction of the target to be investigated.

Remote sensing is used in numerous fields including geography land surveying and most earth science disciplines for example hydrology ecology meteorology oceanography glaciology geology. The irs system is the largest constellation of remote sensing satellites for civilian use in operation today in the world with 11 operational satellites. It is used to gather information and imaging remotely. It also helps in determining soil moisture and can estimate crop production.

All these are placed in polar sun synchronous orbit and provide data in a variety of spatial spectral and temporal resolutions. With the help of active and passive sensors of remote sensing satellites land use pattern can be mapped. Remote sensing is being used for forecasting weather since 1975. Remote sensing is the examination of an area from a significant distance.

Reconnaissance satellites can pick up and record radio and radar transmissions while passing over a country and they can be used as an orbital weapon by placing warheads on a low orbit satellite to be launched at a ground target. Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object and thus in contrast to on site observation especially the earth. Remote sensing is observing and measuring our environment from a distance. The spatial resolution specifies the pixel size of satellite images covering the earth surface.
