new contol centre looks like the alien ufo from koi mil gaya.
Moving forward on its plans to rope in the industry in its activities, ISRO is looking towards the launch of the first privately built rocket in the next five years.
The Indian Space Research Organisation has embarked on hiving off production of communication satellites and polar satellite launch vehicles (PSLVs) to the industry.
"We are now setting up a national committee to work out the modalities on how to go about it," ISRO Chairman K. Radhakrishnan told PTI when asked about the agency's plans to rope in the industry for producing PSLVs and communication satellites.
He said the space agency had told the industry representatives at a meeting in Ahmedabad in January that it was looking at PSLVs and communication satellites produced by them.
"My target is five years from now on. Five years from now the first PSLV will roll out from that entity," Radhakrishnan said.
He said the proposed national committee would look at various steps in this regard including the revenue model, technology transfer and related matters.
The space agency is keen to focus on unique science projects, develop remote sensing satellites and do more research and development instead of engaging in the repetitive exercise of building communication satellites and launch vehicles.
The industry participation in development of communication satellites is up to 80 per cent. If satellites and launch vehicles can be produced by industry players, ISRO scientists will be able to concentrate on research-oriented activities, and have greater involvement of academic institutions.

High altitude test of cryogenic engine successful; ISRO to launch GSLV-D5 in July | idrw.org
Scientists at ISRO's Liquid Propulsion Systems Centre here are hopeful of finishing the work on the indigenous cryogenic engine by May 15 after its recent successful test at the high altitude test facility of the centre. The engine will be taken to Sriharikotta for the launch of geosynchronous satellite launch vehicle GSLV D-5 by July.
"A short-duration test in 3.5 seconds confirmed stable ignition of the cryogenic engine. A simulated high altitude condition was created with high capacity pumps in a vacuum chamber and the test proved successful, which has given us a lot of confidence. The engine will be completely ready by May 15, or at the most May 20, after which it will be taken to Sriharikota," LPSC director M C Dathan told TOI on Wednesday.
"One more HAT test is planned early next month to ensure the readiness of the cryogenic facility though it is not mandatory. A review meet of all senior officials of ISRO establishments will be held at Mahendragiri on April 29 to take stock of the facility," Dathan said.
The cryogenic engine uses a propellant combination of liquid oxygen and liquid hydrogen to develop a thrust of 7.5 tonnes to boost the cryogenic upper stage of GSLV-D5. He said the fluid line checking of the liquid oxygen and liquid hydrogen in propellants would be done at Sriharikota and the GSLV-D5 would be launched to put communication satellite GSAT-14 into orbit in the second week of July.
Vikram Sarabhai Space Centre director S Ramakrishnan said they had come a long way from the failure of the GSLV-D3 launch. "We had narrowed down the failure to the hydrogen fuel booster pumps of the engine. After a series of endurance tests and the latest successful HAT test, the engine is now ready."
He said preparations for the launch of polar satellite launch vehicle, PSLV-C22, were also in full swing.

India's first navigation satellite set for July 1 launch
BANGALORE: Indian Space Research Organisation has now scheduled the launch of the country's first navigation satellite for July one after rectifying an anomaly.
"Review is on. It's scheduled to be launched at 11.43 PM on July one", ISRO sources told PTI here today.
The Indian Regional Navigation Satellite System-1A (IRNSS-1A) was scheduled for launch on board Polar Satellite Launch Vehicle (PSLV-C22) on June 12, 2013 at 01:01 hours from Satish Dhawan Space Centre, Sriharikota.
The spacecraft had gone through all electrical checks and was ready for propellant filling. The PSLV-C22 was fully integrated and was undergoing electrical checks.
But during the electrical checks of the launch vehicle early this month, an anomaly was observed in one of the electro-hydraulic control actuators in the second stage, forcing the space agency to postpone the launch.
Bangalore headquartered ISRO has since replaced this actuator.
The 1425 kg IRNSS-1, which will have a life span of about 10 years, will provide satellite-based terrestrial, aerial and marine navigation services and also help in disaster and fleet management and vehicle tracking, an ISRO official said.
ISRO has planned to have a constellation of seven satellites under IRNSS by 2014-15.
IRNSS is an independent regional navigation satellite system, and once all the spacecraft become operational, it would provide position accuracy, similar to Global Positioning System (GPS), of better than 10 metres over India and the region extending about 1,500 km around the country.
"It is designed to provide an accurate real time Position, Navigation and Time (PNT) services to users on a variety of platforms with 24x7 service availability under all weather conditions", the official said.
IRNSS provides two basic services -- standard positioning service for common civilian users and restricted service for special authorised users, ISRO said.

ISRO launches India's first navigation satellite
The IRNSS-1A is the first dedicated Indian Navigation Satellite. In total seven satellites of the IRNSS constellation will be launched and the full constellation will be up during 2014 timeframe.
The Indian Space Research Organisation (ISRO) which has been involved in over 100 missions will for the first time in its 50 years old history will launch a satellite in the night on Monday at 11.40 pm from Sriharikota in Andhra Pradesh.
When the Polar Satellite Launch Vehicle, PSLV- C22 blasts off from Satish Dhawan Space Centre, Sriharikota at 11.40 pm with the Indian Regional Navigation Satellite System (IRNSS-1A) it will be for the first time that the space agency will be launching a satellite at night.
An ISRO spokesperson told dna that the almost midnight launch has been scheduled taking into account the orbit and inclination at which the satellite will be injected into the space. "Also the season of the year has been taken into account for having a midnight launch. If the satellite was to be launched a few months later then it would have been an early morning one," he said.
The IRNSS-1A is the first dedicated Indian Navigation Satellite. In total seven satellites of the IRNSS constellation will be launched and the full constellation will be up during 2014 timeframe.
According to ISRO, the IRNSS is designed to provide accurate position information service for terrestrial (cars, goods transport, buses) aerial (flights) and maritime (shipping) navigation for users in India as well as neighbouring regions extending up to 1,500 km from India's borders/boundaries, which will be its primary service area.
The IRNSS will provide two types of services: Standard Positioning Service (SPS) for all users; and Restricted Service (RS), an encrypted service provided only to authorised users.
The IRNSS System is expected to provide a position accuracy of better than 20 m in the primary service area. This means if your vehicle is at point A on the ground, the error would go only as far as 20 metres, and not more -- which is pretty accurate in terms of navigational aspects.
The IRNSS-1A will be placed in an inclined geosynchronous orbit at 55 degree East longitude with an inclined orbit of 29 degrees with respect to the equator. The satellite will be positioned at 36,000 Kms altitude.
An inclined geosynchronous orbit means that the satellite's orbital plane will be tipped to some number of degrees from the horizontal as compared to the equator. In such cases although the satellite will be geosynchronous (completing one revolution around Earth along with Earth's rotation), it will not be geostationary (fixed in space at one point in relation with a location on Earth).
The entire IRNSS satellite constellation will compromise of three satellites geostationary orbits and four in inclined geosynchronous orbits, of which IRNSS-1A is the first one.
Around 20 minutes into the launch, the rocket Polar Satellite Launch Vehicle-XL (PSLV-XL) will eject the navigational satellite at an altitude of 501 km.
According to ISRO, the 1,425 kg navigational satellite IRNSS (Indian Regional Navigational Satellite System)-1A is intended to provide terrestrial, aerial and marine navigation services and help in disaster and fleet management.
The satellite with a life span of around 10 years is one of the seven satellites constituting the IRNSS space segment — a regional navigational system developed by India designed to provide accurate position information service to users within the country and up to 1,500 km from the nation's boundary line, ISRO said.
Following the Monday launch of navigational satellite, ISRO is planning to launch its communication satellite G-Sat 14 using a heavier rocket — Geosynchronous Satellite Launch Vehicle (GSLV) — powered with a domestic cryogenic engine some time in August this year.
Preparatory work for the G-Sat 14 launch is going ahead at the rocket launch pad in Sriharikota in Andhra Pradesh, around 80 km from in Chennai.
It will be followed by the mission to Mars later this year. The launch of one more remote sensing satellite is also being planned before the end of the year.
Applications of IRNSS:
Terrestrial, aerial and marine navigation, disaster management, vehicle tracking and fleet management, integration with mobile phones, precise timing, mapping and geodetic data capture, terrestrial navigation aid for hikers and travellers, and visual and voice navigation for drivers.
