Indian Remote Sensing satellites provide remote sensing services to India. Data from these satellites are used for various applications like crop production estimation, drought monitoring, land use mapping, and more. The Cartosat-1 satellite has panchromatic cameras with a spatial resolution of 2.5 meters. It collects data that is processed and analyzed to derive information about vegetation, water bodies, and other landscape features with various applications such as malaria risk mapping. Remote sensing technologies allow analyzing large regions from space and measuring energy beyond human vision to enable global monitoring.

3. DEFINITION:-
Remote sensing is the science and art
of obtaining information about an
object, area or phenomenon through
the analysis of data acquired by a
device that is not in contact with the
object, area or phenomenon under
investigation.

REMOTE SENSING PAYLOADS :
The payload performs the function of imaging
an area along the track and transmits the data
for ground processing .
Each Panchromatic camera consists of three 3
mirror off-axis all reflective telescope with
primary, secondary and tertiary mirrors .
The configuration of the electro-optical module
of the camera is given in Fig .

satellite, etc.)
5. Sensors :(Device to detect electro-magnetic radiation) (camera, scanner,
etc.)
6. Detectors: (Handling signal data) (photographic, digital, etc.)
7.Processing :(Handling Signal data) (photographic, digital etc.)
8. Institutionalisation: ( Organisation for execution at all stages of remote-sensing
