China, Pakistan launch joint ‘Shaheen (Eagle) – 4’ Air Drill

China, Pakistan launch joint ‘Shaheen (Eagle) – 4’ Air Drill

September 7, 2015
China and its strategic partner Pakistan have launched a joint air exercise called Shaheen (Eagle)-4 in China. It is fourth edition of air exercise between the air forces of both countries which was launched as part of a series of military exchange programmes between two countries. In this edition of exercise, Chinese contingent was represented by fighter jets, fighter bombers and early warning planes. Pakistani counterpart included fighter jets and early warning planes. Chinese air force by this joint air exercise is willing to expand the scope of cooperation with various countries in the region. The first edition of such joint air drill between both countries took place in Pakistan in March 2011. Late in September 2013 the second drill took place in China’s western Xinjiang Uygur region and third drill again took in Pakistan’s Punjab province in May 2014.

PM Narendra Modi inaugurates Badarpur-Faridabad Metro

PM Narendra Modi inaugurates Badarpur-Faridabad Metro

September 7, 2015
Prime Minister Narendra Modi inaugurated Badarpur-Faridabad Metro in Delhi National Capital Region (NCR). The metro corridor will connect the national capital with the satellite town and give impetus to economic growth in the region by fast transportation of people. It is also first environment-friendly metro in Indian as all the stations and depot have been equipped with solar power plants. Badarpur-Faridabad Metro Corridor It is the 14 kilometre long corridor and has nine stations from Sarai (Delhi) to Escorts Mujesar. It is an extension of the presently operational ITO-Badarpur section of the Delhi Metro. Delhi Metro Rail Corporation (DMRC) is nodal agency in implementing this corridor and has been built at an estimated cost of 2500 crore rupees. Environment-friendly railway stations: The corridor is equipped with solar power generation facilities in all stations and depots to generate nearly 2 megawatt power. Ridership capacity: on the corridor is estimated to be around two lakh per day and help to shift a major portion of the road users to this mode of transport. It will also help to tackle the rush from satellite town as five to six coach-trains will be in service daily.

GSLV Successfully Launches India’s Latest Communication Satellite GSAT-6

GSLV Successfully Launches India’s Latest Communication Satellite GSAT-6

                 

In its ninth flight (GSLV-D6) conducted today, (August 27, 2015), India's Geosynchronous Satellite Launch Vehicle, equipped with the indigenous Cryogenic Upper Stage (CUS), successfully launched GSAT-6, the country's latest communication satellite, into a Geosynchronous Transfer Orbit (GTO).  The achieved orbit is very close to the intended one.   The launch took place from the Second Launch Pad at the Satish Dhawan Space Centre SHAR (SDSC SHAR), Sriharikota, the spaceport of India. This was the fifth developmental flight of GSLV and the third to carry the indigenous CUS.  GSLV-D6 was intended to further test and qualify the CUS developed by ISRO. 

In its oval shaped GTO, the GSAT-6 satellite is now orbiting the Earth with a perigee (nearest point to Earth) of 168 km and an apogee (farthest point to Earth) of    35,939 km with an orbital inclination of 20.01 deg with respect to the equator.

After a smooth 29 hour countdown, the 416 tonne, 49 m tall GSLV-D6 carrying the 2117 kg     GSAT-6, lifted off at 16:52 Hrs IST. About seventeen minutes after lift-off, GSAT-6 was successfully placed in GTO.  

At 4.8 seconds before the countdown reached zero, the four liquid propellant strap-on stages of GSLV-D6, each carrying 42 tonne of liquid propellants, were ignited. At count zero and after confirming the normal performance of all the four strap-on motors, the mammoth      139 tonne solid propellant first stage core motor was ignited and GSLV lifted off. The major phases of the flight included the core motor burn-out, strap on burn-out, ignition of the second stage, separation of the core motor together with strap-ons, payload fairing separation, second stage separation, CUS ignition and its timely shut down after satisfactory performance.  Following this, GSAT-6 separated from CUS about 17 minutes after launch.

Soon after its injection into GTO, the two solar arrays of GSAT-6 were automatically deployed and the Master Control Facility (MCF) at Hassan in Karnataka took control of GSAT-6.

In the coming days, GSAT-6's orbit will be raised from its present GTO to the final circular Geostationary Orbit (GSO) by firing the satellite's Liquid Apogee Motor (LAM) in stages. The satellite will be commissioned into service after the completion of orbit raising operations, deployment of its 6 m wide sieve shaped unfurlable antenna, the satellite’s positioning  in its designated orbital slot of 83 degree East longitude in the GSO and in-orbit testing of its communication payloads. 

Today’s flight of GSLV underscores the success of ISRO in mastering the highly complex cryogenic rocket propulsion technology.  

GSAT-6 Satellite successfully positioned in orbital slot of 83 Degree East

GSAT-6 Satellite successfully positioned in orbital slot of 83 Degree East

September 7, 2015

Indian Space Research Organization (ISRO) has successfully positioned India’s latest communication satellite GSAT-6 into its orbital slot. It was positioned in its orbital slot 83 Degree east after carrying out four drift arresting maneuvers. It has been collocated with other four communication satellites INSAT-4A, IRNSS1C, GSAT 12 and GSAT 10. About GSAT-6 satellite GSAT-6 satellite was carrying S-Band and C-Band transponders meant for public and strategic purposes. It weighs 2117 kg and has mission life of nine years. The satellite is having S-Band Unfurlable Antenna (UFA) of 6 m diameter. This is the largest antenna ever made by ISRO for a satellite. This antenna is utilized for five spot beams over the Indian mainland to exploit the frequency reuse scheme and to increase frequency spectrum utilization efficiency in India. GSAT-6 is the 25th geostationary communication satellite of India and 12th in the GSAT series. Application: It will provide S-band multimedia communication and broadcasting services across the country. C-Band is for strategic purpose and it will provide national security and law enforcement agencies a secured satellite telephony services. Background ISRO had successfully launched GSAT-6 from an indigenous cryogenic engine GSLV-D6 rocket from Sriharikota on 27 August 2015. ISRO had performed successive orbit raising operation of the satellite and had deployed the UFA successfully after the launch.
