EOS-01 (formerly known as RISAT-2BR2 [3] ) is an X-band, synthetic-aperture radar (SAR) based all weather Earth imaging satellite built by the Indian Space Research Organisation (ISRO) for tasks pertaining to forestry, agricultural and disaster management. [4] It is a part of India's RISAT series of SAR imaging spacecraft and would be third satellite in the series including RISAT-2B, RISAT-2BR1 with 120° phasing. [5] EOS-01 has been developed at the cost of roughly ₹ 125 crore (equivalent to ₹147 croreorUS$18 million in 2023). [6]
EOS-1 (RISAT-2BR2) has been launched on board a PSLV-DL PSLV-C49 launch vehicle on 7 November 2020 along with 9 foreign satellites. The satellite was although earlier scheduled for first half of 2020, impact of COVID-19 pandemic in India affected ISRO's activities and delayed a number of programs by months and it was first launch mission of ISRO in 2020. Due to fears of infections amid pandemic, gathering of staff and media were dismissed for this launch. [7]
As per reports on 29 October 2020, RISAT-2BR2 was renamed as "EOS-01" per new naming criteria adopted by ISRO. [8] [9]

Radar Imaging Satellite 1 or RISAT-1, was an Indian remote sensing satellite built and operated by the Indian Space Research Organisation (ISRO). The second RISAT satellite to be launched, it used a C-band 5.35 GHz synthetic-aperture radar (SAR) for Earth observation.
IRNSS-1E is the fifth out of seven in the Indian Regional Navigational Satellite System (IRNSS) series of satellites after IRNSS-1A, IRNSS-1B, IRNSS-1C and IRNSS-1D. It is one among the seven of the IRNSS constellation of satellites launched to provide navigational services to the region. The satellite was placed in geosynchronous orbit. IRNSS-1E has been successfully launched into orbit on 20 January 2016
EOS-04 or Earth Observation Satellite - 04 is an Indian Space Research Organisation Radar Imaging Satellite designed to provide high-quality images under all weather conditions for applications such as Agriculture, Forestry & Plantations, Soil Moisture & Hydrology and Flood mapping. It is a follow on to RISAT-1 satellite with similar configuration. The satellite is developed by the ISRO and it is the sixth in a series of RISAT satellites.
PSLV-C38 was the 40th mission of the Indian Polar Satellite Launch Vehicle (PSLV) program and its 17th mission in the XL configuration. PSLV-C38 successfully carried and deployed 31 satellites in Sun-synchronous orbit.
