Home Minister Amit Shah extends his congratulations to ISRO on the successful launch of the Earth Observation Satellite-8.
New Delhi [India], August 16 : On Friday, Union Home Minister Amit Shah extended his congratulations to the Indian Space Research Organisation (ISRO) following the launch of the Earth Observation Satellite-8 (EOS-8) from the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh.
In a message on the social media platform X, he stated, "Congratulations to ISRO on the launch of SSLV-D3. This mission will improve Earth's sustainability by aiding environmental monitoring and disaster management."
He also emphasized the leadership of Prime Minister Narendra Modi, noting, "This achievement reflects Bharat's dedication to humanity under the guidance of PM Shri Narendra Modi Ji."
Earlier in the day, ISRO successfully launched the Earth Observation Satellite-8 (EOS-8) from the Satish Dhawan Space Centre.
ISRO's message on X highlighted that "The third developmental flight of SSLV was successful. SSLV-D3 accurately placed EOS-08 into its orbit. This concludes the SSLV Development Project by ISRO/DOS. With technology transfer, Indian industry and NSIL India will now handle SSLV production for commercial missions."
The six-and-a-half-hour countdown for the launch began at 2:47 am. This was the third and final developmental flight of the SSLV-D3/EOS-08 mission, with the spacecraft designed for a mission duration of one year.
The main goals of the EOS-08 mission include designing and developing a microsatellite, creating payload instruments compatible with the microsatellite bus, and incorporating new technologies for future operational satellites, as noted in an ISRO release.
The EOS-08, built on the Microsat/IMS-1 bus, carries three payloads: the Electro-Optical Infrared Payload (EOIR), the Global Navigation Satellite System-Reflectometry Payload (GNSS-R), and the SiC UV Dosimeter.
The EOIR payload is designed to capture images in the Mid-Wave IR (MIR) and Long-Wave IR (LWIR) bands both day and night, for uses including satellite-based surveillance, disaster monitoring, environmental observation, fire detection, volcanic activity observation, and industrial and power plant disaster monitoring.
The GNSS-R payload showcases the use of GNSS-R-based remote sensing for applications like ocean surface wind analysis, soil moisture assessment, cryosphere studies over the Himalayan region, flood detection, and inland waterbody monitoring.
The satellite is set to operate in a circular low-earth orbit (LEO) at an altitude of 475 km with an inclination of 37.4°, and has a mission life of one year. The satellite weighs approximately 175.5 kg and generates about 420 W of power.
It interfaces with the SSLV-D3/IBL-358 launch vehicle. EOS-08 represents a significant step forward in satellite mainframe systems, including an integrated avionics system known as the Communication, Baseband, Storage, and Positioning (CBSP) Package, which consolidates multiple functions into a single, efficient unit.
This system features cold redundant systems using commercial off-the-shelf (COTS) components and evaluation boards, supporting up to 400 GB of data storage.
Additionally, the satellite is equipped with a structural panel embedded with a PCB, an embedded battery, a Micro-DGA (Dual Gimbal Antenna), an M-PAA (Phased Array Antenna), and a flexible solar panel, all crucial for demonstrating on-board technology.
