For band 6, the center wavelength is shifted from 670 nm to 620 nm to improve the reflectance from suspended sediments; for band 7, the center wavelength is shifted from 760 nm to 740 nm to avoid oxygen absorption. OCEANSAT-2 Announcement of Opportunity- modified version March 2008 orbital period is 99.31 minutes and the repetevity cycle is 2 days.
Quicklook display, browse generation, calibration analysis and ADIF (Auxiliary Data File) generation will be carried out here. The OCM data will be transmitted on the I-channel, while the OSCAT / ROSA data will be transmitted on the Q-channel. A new algorithm for total suspended matter (TSM) concentration estimation has been used for OCM-2, which makes use 620 nm band.
OceanSat-2 will play an important role in forecasting the onset of the monsoon and its subsequent advancement over the Indian subcontinent and over South-East Asia.
- LAC (Local Area Coverage): 360 m (cross-track) x 236 m (along-track)
The main objectives of OceanSat-2 are to study surface winds and ocean surface strata, observation of Oceansat-2 will carry three payloads for ocean-related studies, namely, Ocean Colour Monitor-2 (OCM-2), a The scientific payload contains three instruments. OceanSat-2 Launched: 2009 Organisation: ISRO - India Launched 23 Sep 2009 Designed to provide service continuity for operational users of the Ocean Colour Monitor (OCM) instrument on OceanSat-1. OCM is flown on IRS-P4/OceanSat-1, launched May 26, 1999. - The OceanSat-2 mission was approved by the Government of India on July 16, 2005. - Multiple 1 K complex FFTs of the de-chirped data All onboard subsystems are supplied with two raw buses of 28 - 42 V, and DC-DC converters are used to derive required voltage lines. OceanSat-2. • Detection and monitoring of phytoplankton blooms • The OceanSat-2 spacecraft and its sensor complement are operating nominally in 2012 (3
Oceansat-2 is designed to provide service continuity for operational users of the Ocean Colour Monitor (OCM) instrument on Oceansat-1 and enhance the potential of applications in other areas. OCEANSAT-2 is a global mission and is configured to cover global oceans, and provide continuity of ocean colour data with global wind vector and characterization of lower atmosphere and ionosphere. - Solar panels: 3 on either side of S/C, sun-tracking, area = 15.12 m
Two enhanced features have been set up to ease access to these collections: The blue lines are the satellites tracked by the POD antenna. • The receiver processing is performed by an ADSP-21020 (Analog Devices Signal Processor-21020). Both nanosatellites are equipped with newly developed types of spaceborne AIS receivers. OCM is flown on IRS-P4/OceanSat-1, launched May 26, 1999. Oceansat-2 is ISRO’s second in the series of IRS satellites dedicated for ocean research.

The secondary payload (CubeSat) launch service provider (supporting integration and contracting efforts) is ISIS (Innovative Solutions In Space), Delft, The Netherlands. - Payloads: 15 ± 2ºC for OCM, 5 - 45ºC for OSCAT CONFERENCE PROCEEDINGS The onboard range compression signal processor algorithm implemented in Xilinx XQVR600 FPGA is based on periodogram estimation approach, where multiple 1K FFT of contiguous (50% overlapped) data partitions are averaged and binning is performed on the averaged spectrum to obtain signal+noise and noise-only energy estimates.
