Which activities are IRS satellites used?

Explanation: Indian Remote Sensing Satellite (IRS) is used for monitoring and management of natural resources (e.g. locating ground water resources, mineral exploration etc.) and Disaster Management Support.

What is the full form of IRS in remote sensing?

Following the successful demonstration flights of Bhaskara-1 and Bhaskara-2 satellites launched in 1979 and 1981, respectively, India began to develop the indigenous Indian Remote Sensing (IRS) satellite program to support the national economy in the areas of agriculture, water resources, forestry and ecology, geology.

What is feature of IRS?

Characteristics of IRS Satellites: The quality of data acquired by earth surface observation satellites depends on the sensors used in the satellites. The four major characteristic features of sensors are spatial resolution, spectral resolution, radiometric resolution and temporal resolution.

What is remote sensing satellite?

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). Cameras on satellites can be used to make images of temperature changes in the oceans.

Which orbit type are most remote sensing satellites in?

-polar orbits
Most of the remote sensing satellite platforms today are in near-polar orbits, which means that the satellite travels northwards on one side of the Earth and then toward the southern pole on the second half of its orbit. These are called ascending and descending passes, respectively.

In which activities are Indian remote sensing IRS satellites used?

a Indian Remote Sensing IRS satellites are used in Assessment of crop productivity Locating groundwater resources and Mineral exploration. This system was launched in 1979 and 1981. This system is used in agriculture water resources forestry and ecology geology marine fisheries and coastal management.

In which of the activities are Indian remote sensing satellite used?

Indian Remote Sensing satellite is used for various applications like pre-harvest crop area and production estimates, drought, and irrigation monitoring, assessment based on vegetable conditions, flood risk zone mapping and flood assessment, Hydro-geomorphologic maps for locating underground water resources for …

Which type of satellite is IRS?

Indian Remote Sensing Satellite System
The Saga of Indian Remote Sensing Satellite System. IRS-1A, the first of the series of indigenous state-of-art operating remote sensing satellites, was successfully launched into a polar sun-synchronous orbit on March 17, 1988 from the Soviet Cosmodrome at Baikonur.

Which type of satellite is INSAT?

geostationary satellites
The Indian National Satellite System or INSAT, is a series of multipurpose geostationary satellites launched by ISRO to satisfy the telecommunications, broadcasting, meteorology, and search and rescue operations. Commissioned in 1983, INSAT is the largest domestic communication system in the Indo-Pacific Region.

What is GIS GPS and remote sensing?

Remote sensing is a GIS data collection and processing technique. GPS (global positioning system) is a way to assign a location to a point on the Earth. Remote sensing is the use of sensors on board either planes or satellites to collect data usually in a grid like pattern of pixels called raster data.

What are the different types of remote sensing instruments?

Overview Remote sensing instruments are of two primary types: 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.

What are the different types of IRS-IA sensors?

IRS-IA has two types of imaging sensors, one with a spatial resolution of 72.5 meters and designated as LISS-I and other with two separate imaging sensors designated as LISS-IIA and LISS-IIB with a spatial resolution of 36.25 meters each.

What do you need to know about remote sensing?

After reading this article you will learn about:- 1. Principles of Remote Sensing 2. Types of Remote Sensing 3. System Overview. Remote Sensing (RS) is generally defined as the science of collecting and interpreting information about a target without being in physical contact with the object under study.

How big is IRS-1A Indian Remote Sensing Satellite?

IRS-1A (Indian Remote Sensing Satellite-1A) The spacecraft bus is box-shaped (1.6 m x 1.6 m x 1.5 m) with two solar panels (8.6 m 2) as shown in Figures 1 and 4. The S/C structure is made of aluminum/aluminum honeycomb. The satellite is three-axis stabilized utilizing a zero momentum system.
