Why in news
The Indian Space Research Organisation (ISRO) on August 16 launched the EOS-08 Earth Observation Satellite onboard the Small Satellite Launch Vehicle (SSLV)-D3 from the Satish Dhawan Space Centre in Sriharikota
EOS-08
EOS-08 is ISRO’s latest Earth Observation Satellite
Launched by the Small Satellite Launch Vehicle (SSLV)-D3.
Objectives :
designing and developing a microsatellite,
creating payload instruments compatible with the microsatellite bus,
incorporating new technologies required for future operational satellites.
EOS-08 Satellite Overview:
Bus: Built on ISRO’s Microsat/IMS-1 bus.
3 Payloads:
EOIR (Electro Optical Infrared): Captures images in Mid-Wave IR (MIR) and Long-Wave IR (LWIR) for surveillance, disaster monitoring, and environmental studies.
GNSS-R (Global Navigation Satellite System-Reflectometry): Used for ocean surface wind analysis, soil moisture, cryosphere studies, flood detection, and inland waterbody detection.
SiC UV Dosimeter: Monitors UV irradiance and serves as a radiation alarm for the Gaganyaan Mission.
Technology Demonstrations:
Integrated Avionics System:
Communication, Baseband, Storage, and Positioning (CBSP) Package.
Structural Panel: Embedded with PCB.
Micro-DGA: Dual Gimbal Antenna.
M-PAA: Phased Array Antenna.
Flexible Solar Panel.
Nano Star Sensor.
Mission Configuration:
Circular Low Earth Orbit (LEO) at 475 km altitude with a 37.4° inclination.
Mission Life: 1 year.
Additional Payload: SR-0 DEMOSAT developed by Space Kidz India.
SSLV Features:
Capability: Launches Mini, Micro, or Nano satellites (10 to 500 kg) into a 500 km orbit.
Design: Three-stage launch vehicle with all-solid propulsion stages and a liquid propulsion Velocity Trimming Module (VTM) as the terminal stage.
Benefits: Low cost, quick turnaround, flexibility for multiple satellites, and minimal infrastructure requirements.
