After its launch of the GLSV D5 carrying GSAT 14 in December, ISRO would launch Indian Regional Navigation Satellite System-1B probably in February next year.

I guess CoEP's Swayam pico satellite will be piggybacked as well:
Quote
The launch of Pico satellite, which is being designed and developed by a student team of College of Engineering Pune (CoEP) under the supervision of faculties, has been postponed till March following instructions from the Indian Space Research Organisation (ISRO).

IRNSS 1-B onboard PSLV C24, mission readiness review to be conducted tomorrow.

Quote
"The vehicle will be moved from Bangalore to Sriharikota on March 3, subject to clearances. The launch is likely to be any day after March 31. It might be in the first week of April," ISRO Chairman K Radhakrishnan said.

PTI sources putting the launch date at 31st March preceded by a launch rehearsal on 26th March.

Quote
India’s latest navigational satellite IRNSS 1-B would be launched onboard PSLV C-24 rocket from the spaceport at Sriharikota on March 31.

There would be a two-and-a-half day countdown which would be preceded by a launch rehearsal on March 26, Indian Space Research Organisation (ISRO) sources said today.

“The launch of IRNSS 1-B from the Satish Dhawan Space Centre at Sriharikota is scheduled at 5.20 pm on March 31,” they told PTI.

I might need to lose some sleep that day with the Atlas V/DMSP F-19 and Soyuz-2/Sentinel-1A launches just hours before this!

(BTW 17:14 INST = 11:44 UTC)

Just compared 1B with 1A brochures. 1B (1432 Kg) weighs 7 kg more than 1A (1425Kg). Does any know whether it is typo or really it's weight is increased?

~Prasad

They have the same dry masses. 614 kg. (On page 5 of the brochures - IRNSS-1A, IRNSS-1B)

The injection orbit of 1A was: GTO 284 km x 20,650 km x 17.86 degree inclination to the Equatorial plane
                                 1B is:     GTO 284 km x 20,652 km x 19.2 degree inclination to the Equatorial plane

Final orbits of 1A: GSO 55 E x 29 degree inclination to the Equatorial plane
                      1B: GSO 55 E x 31 degree initial inclination to the Equatorial plane
(Pg 5 has 1B's orbit at 55 E x 29 degree GSO though)

So 1B has to change inclination by a fraction more (from GTO to initial orbit).

But this doesn't make sense. Why would you not use spare fuel capacity on 1A? Why fill the tank to less than full? Evidently 1B - with an identical fuel tank, could hold 7 kg more.

Unless the addition of 7 kg fuel implied that the rocket wouldn't be able to throw it as high/fast; and that the fuel burnt by the satellite (with the lower Isp LAM) to get to where it would have been (had you not tanked the extra 7 kgs) is = or more than 7 kgs.




EDIT: Anyone know the Isp for the LAM? How much delta-V does 7 kg (in a stoichiometric ratio of fuel/ox) provide?

How many days it will take to complete all 5 maneuvers and put satellite into its final destination?

ISRO press release:
http://www.isro.org/pressrelease/scripts/pressreleasein.aspx?Apr04_2014

Quote
After a flight of about 19 minutes, IRNSS-1B Satellite, weighing 1432 kg, was injected to an elliptical orbit of 283 km X 20,630 km, which is very close to the intended orbit.

After injection, the solar panels of IRNSS-1B were deployed automatically. ISRO's Master Control Facility (at Hassan, Karnataka) assumed the control of the satellite. In the coming days, five orbit manoeuvres will be conducted from Master Control Facility to position the satellite in its Geosynchronous Circular Orbit at 55 deg East longitude

The launch was successful and met predefined targets," said Isro chairman K Radhakrishnan. Against the targeted perigee of (nearest distance from earth) of 284km, the satellite achieved 283km. As for the apogee (maximum distance from earth), it fell short of just 20km of the targeted 20,650 km, but well within the margin of plus-minus 675 km

    Well http://www.sac.gov.in/SACSITE/IRNSS-1A.htm says 29° inclination for IRNSS-1A orbit
    This one has always been around 27° according to USSTRATCOM TLEs ???

       IRNSS-1B satellite is successfully placed at 55 deg East longitude, collocated with IRNSS-1A and GSAT-8 satellites. IRNSS-1B satellite performance is normal.
