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.

Wasn't TeLEOS-1 going on C29?

ISRO plans to launch the three remaining IRNSS satellites - which will complete the seven-satellite Indian Regional Navigational Satellite System - by March 31. The first of the three is to be launched on January 20, and the remaining two in March using the Polar Satellite Launch Vehicle (PSLV).http://www.newindianexpress.com/states/kerala/ISROs-RLV-TD-Project-Likely-to-be-Delayed/2015/12/28/article3199197.ece

To be oprational in full capacity it needs seven, minimum being four. It is operating already but with less accuracy and some institutes and marine vessels have had receivers installed for testing.
Edit: With 4 it had 18hr availability and lower accuracy. With five it reached 24hr availability with <20m accuracy

Aah, thanks for pointing it out Ohsin! I hadn't noticed. ;D So they have 3 launch pedestrals for use with SLP - PSLV/GSLV(2) and LVM3(1). I guess the launch pedestral No. II would be moved back into SSAB now for maintenance and begin assembly for the next rocket.

PSLV-C32 successfully launches India's Sixth Navigation Satellite IRNSS-1F
In its thirty fourth flight, ISRO's Polar Satellite Launch Vehicle, PSLV-C32, successfully launched the 1,425 kg IRNSS-1F, the sixth satellite in the Indian Regional Navigation Satellite System (IRNSS) this afternoon from the Satish Dhawan Space Centre SHAR, Sriharikota. This is the thirty third consecutively successful mission of PSLV and the twelfth in its 'XL' configuration.
After PSLV-C32 lift-off at 1601 hrs (4:01 pm) 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 19 minutes 34 seconds, IRNSS-1F Satellite was injected to an elliptical orbit of 284 km X 20,719 km inclined at an angle of 17.866 degree to the equator (very close to the intended orbit) and successfully separated from the PSLV fourth stage. After separation, the solar panels of IRNSS-1F were deployed automatically. ISRO's Master Control Facility (MCF) at Hassan, Karnataka took over the control of the satellite.
In the coming days, four orbit manoeuvres will be conducted from MCF to position the satellite in the Geostationary Orbit at 32.5 deg East longitude.
IRNSS-1F is the sixth of the seven satellites constituting the space segment of the Indian Regional Navigation Satellite System. IRNSS-1A, 1B, 1C, ID and IE, the first five satellites of the constellation, were successfully launched by PSLV on July 02, 2013, April 04, 2014, October 16, 2014, March 28, 2015 and January 20, 2016 respectively. All the five 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 1,500 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.
IRNSS-1G, the remaining satellite of this constellation, is scheduled to be launched by PSLV in April 2016, thereby completing the IRNSS constellation.

I wonder why it refers to this as India's sixteenth orbital launch though.. ???

I believe the article is referring to the 16th geosynchronous transfer orbit (GTO) launch. Of course, ISRO has had a lot more than 16 orbital launches.

maybe 16th on PSLV??William's article - https://www.nasaspaceflight.com/2016/03/india-launches-irnss-1f (https://www.nasaspaceflight.com/2016/03/india-launches-irnss-1f/)

I don't think that's it. PSLV (all versions) has launched 34 times. PSLV-XL has launched 12 times.

I think this is correct.
http://www.isro.gov.in/launchers/list-of-pslv-launches
and
http://www.isro.gov.in/launchers/gslv
give a complete list of PSLV and GSLV launches.
I count 9, PSLV missions to GTO + GSO
and
7 successful GSLV launches.
16 GTO launches in all !

The PSLV-C32 launch as seen from Chennai, India. I took these pictures from my terrace. Chennai is about 80 km from Sriharikota, the launch site.
Please find attached a picture which show strap on boosters 1,2,3 and 4 falling off.

I myself visit Chennai frequently, maybe next time I should time my visit with launch schedules to see them with my own eyes. Can you tell me the places near Chennai (or to its north) that affords the best views?

Thanks Vineeth,
The launch is clearly visible from Chennai on a clear day. But the real beast is the sound. To hear the sound you have to head to Sriharikota. And it is an unforgettable experience. To go inside ISRO you need an invite. I have never been inside. I normally drive up to Pulikat lake where security will not allow you to proceed further. You need to take a small road parallel to the launch pad. You get a decent view from there. The launch pad itself is around 11 km from that location. When the sound arrives, it is an experience. I try to make it for most of the launches. This time I had to turn back because of traffic and I knew that I cannot make it before the launch.
Regards,
Arun

Magnificent side-view! This also makes me wonder if those red stripes are there for visibility rather than just pomp. Also have you ever managed to catch Ullage motors flying off? Thanks for sharing these.
Thanks Ohsin,
I am not sure. Please look at the attached picture. This was captured a few seconds after the rocket cruised for some time after first stage burnout. This happened just before the first stage separation and second stage ignition.
Regards,
Arun
Post by: Ohsin on 03/14/2016 03:20 pm
This time around in launch coverage they zoomed into screen of Mission Director(attached) So ullage motors jettisoned ~11 seconds after first stage separation. In C29 launch I think those were seen.
https://www.youtube.com/watch?v=3-VOIuANGnU
I think we can see shaped charge going off as well!
People as far as Chennai reported seeing FOUR objects drop off after PS1 stage separation. First two I assume must have been Ullage motors and other two, halves of heat shield. Very rare to be seen.
