PSLV-C18 to put four satellites in orbit

Now more clarity has emerged from ISRO about the co-passengers of Meghatropiques on PSLV C18 flight.

The flight is scheduled for launch on Oct 12th @ 11 AM IST.

The other three satellites on board this flight are
The 10-kg SRM Sat , 3-kg Jugnu  and a  Luxembourg  satellite VesselSat.

Note that AIS-SAT which we reported in an earlier post has now been renamed as  Vesselsat

Details are in the news clip here:

Unfortunately as usual the official  ISRO website
is silent after July12 2011  news release about GSAT 12 .

I had written  an email to ISRO pointing to an error in the graphical display in their live transmission of GSAT 12 launch but they have not even acknowledged it,    forget about reaction.

PSLV to Carry Meghatropiques and AIS Sat 1

PSLV in its 18th commercial flight ( PSLV C18 ) is expected to carry French Satellite Megha-Tropiques and  Orbcom's AIS-Sat-1 (equatorial)satellite.

Most powerful PSLV launches communication satellite GSAT 12

In the 18th successful launch of PSLV, viz PSLV- C17, launched GSAT-12,a 1,410 kg communication satellite.

53 hour countdown starts for PSLV C17 launch

As per ISRO press release a 53 hours countdown has started in preparedness and checkout of rocket and other subsystems for the launch of GSAT 12 using a PSLV rocket in flight PSLV C17.

Most-powerful PSLV to launch GSAT-12 next week

Indian Space Research Organisation is using the most powerful configuration of its rocket PSLV to launch a communication satellite from Sriharikota on July 15 as it braces for the nearly Rs 200 crore mission. ISRO opted for this step as there is a large unfulfilled and pressing demand for communication transponders.

GSAT-12, a geosynchronous satellite to be launched by PSLV on Jul 15

GSAT-12 ISRO's Communication Satellite, a geosynchronous satellite to be launched by PSLV.The launch date has been finalized on July 15, 2011, around 16:48 and 17:08 hrs IST.

Want to know about Resourcesat-2 Satellite ???

ISRO, In its 17th flight of India's Polar Satellite Launch Vehicle injected three Satellites viz. RESOURCESAT-2, YOUTHSAT and X-SAT (of Nanyang Technical University, Singapore) into Polar Sun-synchronous orbits on April 20, 2011 from Sriharikota.

I intend to educate the reader on Resourcesat-2 satellite in this post. Next in subsequent posts I intend to enlighten the readers about what is Remote Sensing and how it is carried out using satellites; but presently we concentrate on Resorcesat-2.

The Image shows coverage of this satellite around Earth in about 24 hours on a typical day ( 26Apr2011 in specific )

More on Resourcesat=2 coverage over India

In earlier post I covered details about how the satellite moves around Earth over a day and how it sweeps entire Earth in about 16 orbits every day.
We concentrate now on how exactly the data is captured and is received by the receiving station.

PSLV C17 launch flight sequence

In previous post we brought out various aspects about PSLV launch flight sequence.

How does the 1st orbit of GSAT12 look like ???

Injection orbit of GSAT12 and its launcher has been generated and plotted below as seen from a point above North pole and also along equator to show the inclination.
