just got the news, apparently the 4th firing of LAM was not a success.The craft has failed to reach it's intended orbit.According to some sources they have detected some trouble with LAM....
RH-200 sounding rocket set to be launched at 18:25 hours from the Thumba Equatorial Rocket Launching Station (TERLS) coming Thursday marks the 50th anniversary of a very important event - India’s entry into the space arena.It was on November 21, 1963, at 18:25 IST that the American made Nike-Apache rocket was launched from Thumba, the first rocket to be launched from Indian soil for scientific purposes.
A PSLV rocket launched from Kulasekarapattinam could be put in orbit without a Yaw maneuver and even a GSLV rocket launched from there would require only a 8 degree Yaw maneuver, while the same would require 14 degree Yaw maneuver if launched from Sriharikota.

Veteran Indian Space Research Organisation scientist and former chief general manager of liquid propulsion system centre at Thiruvananthapuram, N. Sivasubramanian, along with locals, on Saturday met and urged Union minister of state in Prime Minister Office V. Narayanasamy to take steps to establish the third rocket launch centre at Kulasekarapattinam in Tamil Nadu. One of the members of the team, which met the minister, later told Deccan Chronicle that the minister had assured them that Sriharikota has not been finalised for the third rocket launch centre. The minister was also learnt to have assured suitable action in the coming session of Parliament to set up the rocket launch centre in the village in southern Tamil Nadu.
It seems ISRO is developing PSLV 3S for launching upto 500 kg payload. The third stage, i.e., PS4 will be 0.8 T loading. Also, ISRO is considering developing ATV EX into a launcher for 200-400 kg nano and micro satellites.
What's ATV EX?
Advanced Technology Vehicles Project was formed to support the new technology areas especially Dual Mode Ram Jet Engine and Scram Jet Engine flight test demonstration. The first development flight of ATV D01(using RH 560 sounding rocket) was a 100% successful flight in which all the vehicle parameters were measured and vehicl characterization was done. The requirement to dwell the vehicle in the defined M-q window for a minimum of 5s was also demonstrated. In the 12th plan, five numbers of ATV development flights are scheduled to be flight tested with Dual Mode Ramjet-Scramjet Engine Modules from 2012 to 2015 and developmental flights of ATV-EX vehicle, improving ATV-D01 configuration with sustainer fins in cruciform configuration to achieve 600 km altitude with 200 kg payload.
And what's the architecture of the proposed PSLV 3S? All solids?
Also, GSLV Mk-II, Mk-III? Cryo-stage? REX? Unless their development teams are full, and there's no room for existing ISRO staff on these teams, why oh why would you develop rockets for the lower range of mass-to-orbit?
"A study is being undertaken on the need for a second launch site and the report is expected in couple of months," Indian Space Research Organisation (ISRO) chairman K.Radhakrishnan told IANS.A senior ISRO official, who did not want to be identified, told IANS that Tuticorin is a good location for a rocket that needs to fly towards south. Radhakrishnan said that for all eastward launches, the current site at Sriharikota is the best."We send the remote sensing (earth observation) satellites southwards. But the global trend in the remote sensing satellites is reduction in their size.""The size of remote sensing satellites is coming down while that of communication satellites is going up. A new rocket launch site for remote sensing satellites, normally launched southwards, has to take into account the capital expenditure involved and the savings in fuel burnt by the rocket. For launching communication satellites the current site is the best," he added.
... a study is being undertaken on constructing third launch pad at Sriharikota capable of launching upgraded geosynchronous satellite launch vehicle (GSLV) Mark III.
Meanwhile, ISRO has decided to construct a new rocket assembly building in order to increase the frequency of rocket/satellite launches and use the existing two launch pads effectively, he said.At present, ISRO has two rocket assembly facilities and two launch pads at its Satish Dhawan Space Centre in Sriharikota.
During the 12th Plan Period, the Indian space agency has planned 58 missions for realization -- 33 satellite missions and 25 launch vehicle missions (17 PSLV, six GSLV Mark II missions and two GSLV Mark III including the experimental one).

@AJA,Looks like the illustration in second article is not correct From what I gather from first article, Sriharikota is ideal for eastward launches, and Kulasekarapattinam would be ideal for southward launches.
