Question

Name India’s first Indian Remote Sensing Satellite.
A) IRS-1A
B) CARTOSAT
C) RESOURCESAT
D) IRS-P3

Answer 1

Hint: First Indian Remote Sensing Satellite was a partly operational and partly experimental project to establish Indian satellite imaging expertise. Satellite to provide images for a number of land-based applications, such as agriculture, forestry, geology and hydrology.The long-term aim of the project was the development of indigenous remote sensing capabilities.

Complete answer:
Remote sensing is a science in which information on objects or areas can be collected from a distance, normally airplanes or satellites. Remote sensors can be active or passive. In response to external stimuli, passive sensors respond.

Option A. IRS-1A: IRS-1A was successfully started on March 17, 1988 from the Soviet Cosmodrome in Baikonur in a polar sun-synchronous orbit of the first sequence of indigenous state-of-the-art Remote Sensing Satellites into polar sun-synchronous orbit.
-IRS-1A is fitted with three cameras, LISS-1, liss-2A and lis-2B, each with a swath width of about 140 kilometers (87 mi), with resolutions of 72.5 meter (238 ft) and 36.25 meter (118.9 ft) respectively. It was conducted by Indian space research organization (ISRO).
-IRS-1A is the first’s Indian remote sensing satellite. Hence, this option is correct.

Option B. CARTOSAT: The satellites of the Indian Space Research Organization are a set of Indian optical earth observation satellites (ISRO).

-The sequence Cartosat is a part of the Remote Sensing Program of India. They are used for the control, protection and monitoring of Earth's resources. CARTOSAT is not the first’s Indian remote sensing satellite. Hence, this option is incorrect.

Option C. RESOURCESAT: Resourcesat-1 (also called IRS-P6) is an Indian space research organisation's advanced remote sensing satellite (ISRO). Resourcesat-1 is the 10th satellite ISRO of the IRS range.
It not only aims to continue with IRS-1C and IRS-1D remote sensing services, both of which have long survived their planned mission lives, it also greatly increases data qualities. RESOURCESAT is not the first’s Indian remote sensing satellite. Hence, this option is incorrect.

Option D. IRS-P3: IRS-P3 was an earth monitoring project under the Indian Space Research Organization program of the National Natural Resources Management System (NNRMS) (ISRO).
-The mission's objectives were to process and interpret data generated from its two payloads, the Wide Field Sensor (Wifi) and the Deutsche Aerospace Centre's Modular Optoelectronic Sensor (MOS).
-IRS-P3 is not the first’s Indian remote sensing satellite. Hence, this option is incorrect.
-IRS-1A is the first sequence of indigenous Remote Sensing Satellites.
Hence, Option A. IRS-1A is the correct answer.

Note:
i) Professor P. R Pisharoty is the father of Indian remote sensing and one of the most distinguished Indian meteorologists of international repute.
ii) As balloonists took pictures of the ground using the newly invented photo-camera, remote sensing started in the 1840s. The popular pigeon fleet operating as an innovation in Europe may have been the most novel platform at the end of the last century.
iii) Evelyn Pruitt, geographer for the United States The first to coin the word 'remote sensing' was the Office of Naval Research.
