This will be the second IRNSS launch this year. Has ISRO officials mentioned the approximate launch date following the success of IRNSS-1B mission?

No launch dates yet. I guess it will be after GSLV Mk3 X1 launch.

As per the present schedule,  a PSLV mission is next in line - in the first or second week of October - after the Mars mission docks with the Red Planet.
The PSLV C-26 mission will have as payload the 1425 kg IRNSS-1C satellite, PSLV project director P Kunhikrishnan said. This is the third of the seven satellites planned in the Indian Regional Navigation Satellite System (IRNSS) series.

Assuming its not a reporter error, I guess this is the second IRNSS launch near midnight after 1A. Are there any particular reasons why such late night launch times are chosen for these GSO sats?

As a minor note, I believe this launch will mark the first time that ISRO makes more than 3 orbital launches in a year. Not a big change in the first appearance, but signifies a gradual scaling up of activities that could accelerate in the coming years, with the commissioning of a second VAB and Third launch pad.

Not sure. They say a small anomaly was found during launch rehearsal. May be something in the LV itself.
Quote
Asked about the reasons for the postponement, a senior ISRO official said, "The rehearsal of the launch was done last night. We have observed a small anomaly. A particular item was not functioning properly."

"After some brainstorming, we decided that all the tests would be done to ensure perfection before launch.The defective item will be replaced. We have to open the heat shield and work, so it will require at least two to three days," he said.

^Since they plan to open the heat shield to fix the issue, the problem is for sure in the LV or S/C and is definitely not in the ground infrastructure.

I think it's great that another IRNSS satellite will go into orbit with this launch. But as a space fan, I just want this launch out of the way so that the main focus will return to the upcoming GSLV Mk3 launch. I'm really fed up of waiting on all the launch postponements for Mk3.

This is my feeling too. In spite of the PSLV being established as reliable and workhorse Launch Vehicle, ISRO should focus on complete the development and operationalization of GSLV MK3 as soon as possible. I have been crying foul over this matter in the last 5 years since G. Madhavan Nair who retired as ISRO chief was quoted as saying that it is the domain of the launch vehicles where India is lagging behind China and the widening gap could be reduced once the GSLV MK3 development and operationalization is complete. But that did not happen.

Otherwise until GSLV MK3 fructifies, ISRO will further fall by the wayside as far as the launching of the Heavy Satellites are concerned.

In a different perspective, it may not really matter much if the GSLV-III-X flight is conducted this year or early next, unless there are chances of major flaws with the lower stage design. The C-25 upper stage has got another 2 years at the minimum before it gets ready. On the other hand, the apparent urgency seen in getting IRNSS up and running indicates that the Govt considers an independent navigation satellite system as of utmost priority for the Indian military. Just my thoughts..

PSLV-C26 Successfully Launches India's Third Navigation Satellite IRNSS-1C
ISRO's Polar Satellite Launch Vehicle, PSLV-C26, successfully launched IRNSS-1C, the third satellite in the Indian Regional Navigation Satellite System (IRNSS), in the early morning hours of today (October 16, 2014) at 0132 hours IST from Satish Dhawan Space Centre, Sriharikota. This is the twenty seventh consecutively successful mission of PSLV. The 'XL' configuration of PSLV was used for this mission. Previously, the same configuration of the vehicle was successfully used six times.

Hon'ble Minister of State (Space), Dr Jitendra Singh, witnessed the launch from the Mission Control Centre at SDSC, Sriharikota.

After the lift-off of PSLV-C26 with the ignition of the first stage, the important flight events, namely, stage and strap-on ignitions, heat-shield separation, stage and strap-on separations and satellite injection, took place as planned. After a flight of about 20 minutes 18 seconds, IRNSS-1C Satellite, weighing 1425 kg, was injected to an elliptical orbit of 282.56 km X 20,670 km, which is very close to the intended orbit.

After injection, the solar panels of IRNSS-1C were deployed automatically. ISRO's Master Control Facility (at Hassan, Karnataka) assumed 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 Geostationary Orbit at 83 deg East longitude.

IRNSS-1C is the third of the seven satellites constituting the space segment of the Indian Regional Navigation Satellite System. IRNSS-1A and IRNSS-1B, the first two satellites of the constellation, were successfully launched by PSLV on July 02, 2013 and April 04, 2014 respectively. Both IRNSS-1A and 1B are functioning satisfactorily from their designated geosynchronous 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 control, satellite ranging and monitoring, etc., have been established in as many as 15 locations across the country.

In the coming months, the next satellite of this constellation, namely, IRNSS-1D, is scheduled to be launched by PSLV. The entire IRNSS constellation of seven satellites is planned to be completed by 2015.
