The remaining two missions are PSLV-based, intended to put two more satellites in the Indian Regional Navigation Satellite System (IRNSS) in orbit.
The PSLV C-29 and the PSLV C-31 will carry one IRNSS satellite each, hopefully by the end of 2015. We hope to have two of the three remaining IRNSS satellites in orbit this year, he said.

There are these 8 pole like bolt-on structures for GSLV strapons (See first two images on following post)PSLV-CA and last XL used the one the right. it is in maintenance spot and will be repainted soon. everything in red is removed before flight.

That includes 37 successful launches, three partial failures, two failures that reached orbit and seven launches that failed to orbit.
I'm somewhat surprised ISRO are not publicising this milestone, given the somewhat less significant (and in some cases arguably manufactured) milestones that they have given significant publicity to in the past.

This will be India's fiftieth orbital launch (4 SLV, 4 ASLV, 33 PSLV, 9 GSLV).
That includes 37 successful launches, three partial failures, two failures that reached orbit and seven launches that failed to orbit.
I'm somewhat surprised ISRO are not publicising this milestone, given the somewhat less significant (and in some cases arguably manufactured) milestones that they have given significant publicity to in the past.
Every agency had gone through bad phases initially. Even Nasa was not exceptional. May be ISRO want to forget those bad phases quickly and progress in success path quickly. GSLV has seen many ups and downs both politically and experimentally bad phases and is now slowly emerging out it on its own.

Good article!

The first two of these, in March 1987 and July 1988, both failed to achieve orbit. The third launch in May 1981 achieved an unplanned, but partially usable orbit, while only the fourth was successful in May 1994.
But, typo? Possibly 1991?

PSLV-C31 Successfully Launches India's Fifth Navigation Satellite IRNSS-1E
ISRO's Polar Satellite Launch Vehicle, PSLV-C31, successfully launched the 1425 kg IRNSS-1E, the fifth satellite in the Indian Regional Navigation Satellite System (IRNSS) today morning (January 20, 2016) from Satish Dhawan Space Centre SHAR, Sriharikota. This is the thirty second consecutively successful mission of PSLV and the eleventh in its 'XL' configuration.
After the PSLV-C31 lift-off at 0931 hrs (9:31 am) IST from the Second Launch Pad with the ignition of the first stage, the subsequent important flight events, namely, strap-on ignitions and separations, first stage separation, second stage ignition, heat-shield separation, second stage separation, third stage ignition and separation, fourth stage ignition and satellite injection, took place as planned. After a flight of about 18 minutes 43 seconds, IRNSS-1E Satellite was injected to an elliptical orbit of 282.4 km X 20,655.3 km inclined at an angle of 19.21 degree to the equator (very close to the intended orbit) and successfully separated from the PSLV fourth stage. After injection, the solar panels of IRNSS-1E were deployed automatically. ISRO's Master Control Facility (at Hassan, Karnataka) took over the control of the satellite. In the coming days, four orbit manoeuvres will be conducted from Master Control Facility to position the satellite in the Geosynchronous Orbit at 111.75 deg East longitude with 28.1 deg inclination.
IRNSS-1E is the fifth of the seven satellites constituting the space segment of the Indian Regional Navigation Satellite System. IRNSS-1A, 1B, 1C and ID, the first four satellites of the constellation, were successfully launched by PSLV on July 02, 2013, April 04, 2014, October 16, 2014 and March 28, 2015 respectively. All the four satellites are functioning satisfactorily from their designated orbital positions.
IRNSS is an independent regional navigation satellite system designed to provide position information in the Indian region and 1500 km around the Indian mainland. IRNSS would provide two types of services, namely, Standard Positioning Services (SPS) - provided to all users - and Restricted Services (RS), provided to authorised users.
A number of ground stations responsible for the generation and transmission of navigation parameters, satellite ranging and monitoring, etc., have been established in eighteen locations across the country. In the coming months, the remaining two satellites of this constellation, namely, IRNSS-1F and IG, are scheduled to be launched by PSLV, thereby completing the entire IRNSS constellation.
