OCEANSAT TWO LAST

Besides two German Rubin nano satellites, other Oceansat-2
co-passengers are four cubesats: Beesat, built by Technical
University Berlin, UWE-2 (University of Wuerzburg Germany),
ITU-pSat(Istanbul Technical University Turkey) and SwissCube-1
(Ecole Polytechnique Federal de Lausanne, Switzerland).
The nano satellites are in the two-eight kg range.
Oceansat-2 and the six auxillary payload would be
ejected into a polar Sun Synchronous Orbit, ISRO officials
said.
The nano satellites are educational spacecrafts from
European Universities intended for testing new technologies.
Oceansat-2 would be injected into space first and the
remaining one after another, officials said.

The eight band Ocean Colour Monitor carried by Oceansat-2
images a swath (strip of land or ocean) of 1,420km with a
resolution of 360 metre and works in the visible and Near
infrared region of the electromagnetic spectrum. The
Scatterometer covers a swath of 1,400 km and operates
continuously.

In April 2008, ISRO had launched 10 satellites in a
single mission --one big spacecraft (Cartosat-2A) and nine
nano satellites.

PSLV-C14 during its path, has four stages using solid and
liquid propulsion systems alternately. The first stage,
carrying 139 tonne of propellant, is one of the largest solid
propellant boosters in the world while the second stage
carries 41.5 tonne of liquid propellant. In the third the
satellite uses 7.6 tonne of solid propellant and the fourth
has a twin engine configuration with 2.5 tonne of liquid
propellant. (MORE) PTI
