Recently the Earth Observation Satellite (EOS-04) of the Indian Space Research Organization and two other small satellites (INSPIREsat-1 and INS-2TD) were successfully placed in the desired orbit by PSLV-C52 rocket.
It was the 54th flight of the Polar Satellite Launch Vehicle (PSLV) and its 23rd most powerful XL-version with six strap-on boosters.

Earth observation satellites are satellites equipped with remote sensing technology, which collect information about the physical, chemical and biological systems of the Earth.
Many Earth observation satellites are deployed in sun-synchronous orbit.
Other earth observation satellites launched by ISRO include RESOURCESAT-2, 2A, CARTOSAT-1, 2, 2A, 2B, RISAT-1 and 2, Oceansat-2, Megha-Tropiques, Saral and SCATSAT-1, INSAT-3DR, 3D included.

EOS-04:

EOS-04 weighs 1,710 kg and is designed to provide high quality images in all weather conditions with a mission duration of ten years for applications such as agriculture, forestry and plantation, soil moisture and hydrology, and flood mapping has been done.
It will complement the data from RESOURCESAT, CARTOSAT and RISAT-2B series satellites, which are already in orbit.
The first satellite in the series of these satellites – EOS-01 was launched in November 2020 and is still in orbit. EOS-02 will be launched on a new launch vehicle named SSLV (Small Satellite Launch Vehicle), while the launch of EOS-03 failed in August, 2021.
It will be placed in a Sun-synchronous polar orbit of 529 km. It is a radar-imaging satellite, making it a part of the ‘RISAT’ series. Today Current Affairs.
It will replace RISAT-1, which was launched in the year 2012, but has not been functional since last few years.
RISAT Synthetic Aperture Radar is used to obtain high-resolution images of the land.
A major advantage of radar imaging over optical instruments is that it is unaffected by weather, clouds or fog or lack of sunlight.
It can capture high-quality images in all conditions and at all times, making it perfect for surveillance.

INSPIREsat-1:

INSPIREsat-1 is part of a group of satellites planned under the International Satellite Program in Research and Education, which includes the Small-Spacecraft Systems and Payload Center (SSPACE), University of Colorado (US), Nanyang the Technological University (NTU) consists of the Small-Spacecraft Systems and Payload Center (SSPACE), Singapore and the National Central University (NCU), Taiwan. The Hindu Analysis.
INSPIREsat-1 carries two scientific payloads with a mass of 8.1 kg and a one-year mission with the aim of improving the understanding of the dynamics of the ionosphere (part of Earth’s upper atmosphere) and the coronal heating processes of the Sun.

INS-2TD:

INS-2TD is a technology demonstrator for the first India-Bhutan joint satellite to be launched in March 2022.
The two countries signed a space agreement last year, under which Bhutansat or INS-2B would be launched by PSLV rocket in March 2022.
INS-2TD’s thermal imaging cameras are for Earth observation, such as estimating land and water surface temperatures and identifying forest and tree cover.

India currently has 53 operational satellites, of which 21 are earth observation and the other 21 are communication based.
Eight are navigation satellites, while the remaining three are science satellites.
