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

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?

ISRO press release:
http://www.isro.org/pressrelease/scripts/pressreleasein.aspx?Apr04_2014After 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
