OceanSat-1
Oceansat-1 was the first Indian satellite built specifically for oceanographic applications.
The satellite was launched by ISRO’s PSLV-C2 on 26 May 1999 from the first launch pad of Satish Dhawan Space Centre in Sriharikota, This satellite is the 8th satellite of the IRS satellite series of India. It was the third successful launch of PSLV.

SCATSAT-1
SCATSAT-1 carries a Ku-band scatterometer similar to the one on Oceansat-2.
The satellite was launched in 2016 after SCAT (Scanning scatterometer) on Oceansat-2 became dysfunctional after its life span of four-and-a-half years.
OceanSat-3
Oceansat-3 Expected launch date between August–September 2022.
The satellite will provide continuity to operators of OCM and enhanced ability in other applications by way of simultaneous Sea Surface Temperature (SST) measurements.
