India on Monday morning successfully put
into orbit its own weather satellite SCATSAT-1 in a copy book style. The Total Investment & Insurance

In the second phase of its mission, the
rocket will launch seven other satellites - five foreign and two Indian -
between 11.25 to 11.28 a.m., in a different orbit.
Exactly at 9.12 a.m., the PSLV rocket
standing 44.4 metres tall and weighing 320 tonne tore into the morning skies
with fierce orange flames at its tail.
Gathering speed every second, the rocket
raced towards the heavens amidst the cheers of the Indian Space Research
Organisation (ISRO) officials and the media team assembled at the rocket port
here.
At the rocket mission control room,
Indian space scientists at ISRO were glued to their computer screens watching
the rocket escaping the earth's gravitational pull.
Seventeen minutes into the flight, the
rocket's main cargo, the 371 kg SCATSAT-1 - for ocean and weather related
studies - was injected into a 730 km polar sun synchronous orbit.
Although SCATSAT-1 is a follow-on
mission for Oceansat-2 improvements have been made in the satellite's hardware
configuration based on lessons learnt from Oceansat-2 instruments.
Also SCATSAT-1's payload has been
characterised with the objective of achieving data quality for Climate Data
Records, apart from facilitating routine meteorological applications, the ISRO
said.
It said the SCATSAT-1's scatterometer
will provide wind vector data products for weather forecasting, cyclone
detection and tracking services to the users.
The satellite carries Ku-band
scatterometer similar to the one flown onboard Oceansat-2.
The mission life of the satellite is
five years.
The remaining seven satellites will be
placed in a 689 km polar orbit later.
These seven satellites include five
foreign satellites: three from Algeria (Alsat-1B 103kg, Alsat-2B 117kg,
Alsat-1N 7kg), and one each from Canada (NLS-19, 8kg) and US (Pathfinder-44kg).
The two other Indian satellites are:
Pratham (10kg) built by Indian Institute of Technology-Bombay (IIT-B) and Pisat
(5.25 kg) from PES University, Bengaluru and its consortium.
According to the ISRO, the two Algerian
satellites Alsat-1B and Alsat-2B are remote sensing satellites while Alsat-1N
is a technology demonstration nano satellite for Algerian students.
On the other hand, the US satellite
Pathfinder-1 is a commercial high resolution imaging micro satellite while the
Canadian NLS-19 satellite is la technology demonstration nano satellite for
experimentation in helping to reduce space debris and for tracking commercial
aircraft.
The IIT-B's satellite Pratham's mission
objective is to estimate the total electron count with a resolution of 1km x
1km location grid while Pisat from PES University and its consortium is a nano
satellite for remote sensing applications. The Total Investment & Insurance Solutions
After slinging SCATSAT-1 into its orbit
the rocket's fourth stage will be restarted one hour 22 minutes into the flight
and cut off around 20 seconds later.
Two hours and 11 minutes into the flight
the fourth stage will again be restarted to be cut offAone minute later. The Total Investment & Insurance

Following that in three minutes all the
seven satellites will be ejected putting an end to PSLV's longest mission till
date. The Total Investment &

The PSLV rocket is a four stage/engine
rocket powered by solid and liquid fuel alternatively.
Vikram Sarabhai Space Centre (VSSC)
director K. Sivan told IANS on Sunday that the long time gap between the
cutting off of the engine and its restart was not an issue.
Sivan said the first time the multiple
burn technology was first tested by ISRO while flying its PSLV rocket on
December 16, 2015 and in June 2016, the technology was again demonstrated.
About the challenge, Sivan said:
"After cutting off the engine, its condition should be brought to such a
stage that it could be restarted again. The next challenge is to controlling
the engine and bringing it so as to eject the remaining satellites into a
different orbit." The Total

He said the rocket has GPS aided
navigation system so that data generated by the rocket's inertial navigation
system and the one provided by the former will be blended so as to erase and
errors and to generate a precise data.The
