Oceansat-3 Introduction

ISRO has launched the EOS-06(Oceansat-3) satellite on 26 Nov 2022 in a polar sun-synchronous orbit at 740km altitude. EOS-06(Oceansat-3) is the third-generation satellite in the Oceansat series. This is to provide continuity services of Oceansat-2 spacecraft with enhanced payload specifications as well as application areas.

EOS-06(Oceansat-3) has three main instruments, 13-band advanced Ocean Colour Monitor, Ku-band Scatterometer and a 2-channel Sea Surface Temperature Monitor. ARGOS is the fourth provided by French Space Agency (CNES). Unfortunately, the SSTM developed a technical problem in scan mechanism and therefore, not in operation at present.

Payloads on EOS-06(Oceansat-3) are :

  Ku-band Scatterometer (SCAT-3)

 13-band Ocean Colour Monitor (OCM-3)

 2-band Sea Surface Temperature Monitor (SSTM)

 ARGOS by CNES French Space Agency

Applications planned using EOS-06(Oceansat-3) datasets are as follows :

  • Marine Resource Management
  • Carbon & Nitrogen Cycling in Ocean
  •  Phytoplankton biodiversity
  •  Zooplankton & secondary pro
  •  Algal bloom detection and monitoring
  •  Climate change studies
