ISRO press release:
http://www.isro.org/pressrelease/scripts/pressreleasein.aspx?Apr04_2014QuoteAfter 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
