ISRO to set up research centre in Guwahati

http://www.assamtribune.com/scripts/detailsnew.asp?id=oct0617/city051

GUWAHATI, Oct 5 - The Indian Space Research Organisation (ISRO) will set up a research centre in Guwahati for start-ups, academicians, environmentalists and entrepreneurs. A decision to this effect was taken at a meeting between Chief Minister Sarbananda Sonowal and ISRO Chairman Dr AS Kiran Kumar held at the Lokapriya Gopinath Bordoloi International Airport here today. It is for the first time that the ISRO is setting up such an exclusive research facility in Assam to explore the possibility of using geospatial technology, which includes data generated through Global Positioning System (GPS), Geographical Information Systems (GIS) and Satellite Remote Sensing for expediting development of Assam and using the remote sensing technology for accurate flood warning system, prevention of soil erosion and landslide, etc.

In course of the meeting, Chief Minister Sonowal requested the ISRO chief to integrate space technology for the overall development of the State. He informed Dr Kumar that the State government would provide land to the ISRO free of cost for opening the research centre.

Along with other activities, the research centre will be mandated to be used extensively for collecting and interpreting satellite data over the last few decades which can be made accessible to young researchers.

Sonowal also informed that the State government would ink an MoU with the Department of Space for leveraging the potential of the State for using space technology. Once the MoU is signed, both the State government and the ISRO will work together for development of the region.

Referring to Prime Minister Narendra Modi’s special thrust on the North East and considering the region as the new growth engine of the nation, Sonowal requested Dr Kumar to integrate space technology with the Act East Policy so that space technology can be used as a bridge between the North East and other South East Asian countries.

Drawing the ISRO chief’s attention to the verdant natural resources of Assam – both flora and fauna – and the Brahmaputra and Barak providing the lifeline to the entire State, Sonowal sought the ISRO’s help in using space technology for drawing a broad remote sensing map to stop the alleged illegal trade on natural resources. He also sought the ISRO’s help to use space technology as a deterrent against deforestation which is largely responsible for sedimentation and siltation of the riverbeds.

Sonowal also hoped that both the State government and the ISRO can work together in carrying out a survey in studying the depth of the Brahmaputra which, according to him, would help in the State government’s proposed move to dredge the mighty river along its entire stretch in the State from Sadiya to Dhubri.

Chief Secretary VK Pipersenia; Additional Chief Secretary Science and Technology Rajiv Bora; Scientific Secretary, ISRO Bangalore PG Diwakar; Director National Remote Sensing Centre, Hyderabad YVN Krishnamurthy; Director North East Space Application Centre, Shillong PLN Raju; Director ISRO Bangalore Shantanu Bhatwadekar; Scientist, North East Space Application Centre Shillong Jonali Goswami and other senior officers of the government were present in the meeting.

Think of guaranteed encryption end to end. Basically unhackable or untappable lines of communication utilizing quantum properties.
Is it based on same technology (that exploits quantum mechanics for communication or maybe cryptography also) on which blue-laser submarine communication is based? I ask because this announcement comes close on the heels of an announcement about some DRDO lab achieving a breakthrough in blue-laser communication tech some days ago, and it sounds similar.

No blue laser communication developed by drdo and quantum communication are not the same thing. Blue laser based on 3-5 semiconductors like GaN(which we are building a foundry in IISC) is a conventional technology where the high penetration of blue light in water is used as a mode of communication with submarines.But the encryption remains standard military encryption based on factoring a large polynomial number by prime number eg : RSA algorithm. This encryption technique is well documented and it requires 1000s of years of a modern supercomputer to perform the factorization. But scientist began working quantum computers which uses quibits and quantum logic gates in place of digital logic gates and binary bits. Quantum computers(yet to be built) will increase our computational power exponentially and making our current encryption technology vulnerable. Hence scientist started working on quantum communication technology where photons trapped in cold gases will be entagled state and any means to snoop in on the communication by 3rd part will collapse the entagled state of the photons and make the communication unhackable.
Besides China is making rapid stides in quantum communication systems and hence our effort is a welcome developement

This is pretty interesting stuff.
Correct me if I am wrong but what my interpretation of this news is that ISRO has achieved a demonstration of this capability. So what I now understand is that we have achieved quantum teleportation like what China achieved in 2010, according to this article here:

Its in its infancy. It would take atleast 2 decades to fully incorporate it in military communication system.
Till now no one have made any serious advancement in this regard. Recently China had launched one quantum communication satellite for testing purpose and been able to teleport a photon with it.

No news is out regarding this till now. Whether ISRO had been able to teleport photon in free space or not is yet to be seen. Moreover we would have to launch satellite for testing purpose before announcing its success.

Then what does this tweet mean:-

Also, we can test it without having to send the satellite. That is what the Chinese did in 2010. They performed a quantum teleportation over a distance of 16 kilometers. Read this here: China’s Secure Communications Quantum Leap
In May 2010 a team of 15 Chinese researchers from Tsinghua University in Beijing and the Hefei National Laboratory for Physical Sciences, a government-directed research center, published a research paper announcing a successful demonstration of “quantum teleportation” (liangzi yinxing chuan) over 16 kilometers of free space.

The tweet is only saying that they had developed satellite based quantum communication system. It could mean anything. Most probably transmitter and receiver.

I have been following Chinese progress in this. Now what they have done is an achievement. In 2010 they have tested it across free space, they had not been upfront that whether they mean vaccum by this. Its only recently that they had been able to transmit a photon all the way from space to earth station. So for testing, you do need a satellite up there.

Recently a pic is doing round and been posted in last page here about a structure coming up in Sathish Dhawan Space Centre. I would be not amused if it is a part of it.

The LAMP Group (Raman Research Institute) has one of the first labs in the country to develop the technology of single photon sources based on spontaneous parametric down conversion in bulk non-linear crystals. The single photons and their various degrees of freedom are used to investigate aspects of quantum optics and quantum information.
In collaboration with ISRO they are probably trying to send a satellite in space which will perform quantum communication.

Story of the Week
Successful completion of One Year of Service by SCATSAT-1 Scatterometer
SCATSAT-1, the state-of-the-art satellite with a dedicated Scatterometer payload was launched on September 26, 2016. It is a continuity mission for Oceansat-2 Scatterometer (OSCAT) to provide wind vector data products for weather forecasting, cyclone detection and tracking services to the users. SCATSAT-1 inherits the design of OSCAT, hence operates in Ku-band having 13.53GHz central frequency and having a pencil beam design with two beams with incidence angles of 490 and 570 on ground with HH and VV polarization respectively. With a swath width of 1800 km, this instrument covers 90% of the earth’s surface in a single day. With the experience gained through OSCAT, a few improvements have been made to the sensor characteristics for better sensitivity in backscatter especially in Polar Regions.

The radar backscatter measurement of SCATSAT-1 has commenced with the switch-on of main TWTA (Traveling Wave Tube Amplifier) on October 03, 2016. The instrument had undergone calibration and validation (Cal-Val) phase during which sensor stability monitoring, fine-tuning of algorithms have taken place. As the sensor is providing very high quality observations without any glitch, which provided good confidence on the instrument performance and led to the early public release of wind products (Beta version) through MOSDAC and NRSC as a Beta version on October 22, 2016. Subsequently after successful completion of the Cal-Val phase, the mission entered into operational phase from April 21, 2017.

The main operational products from this mission are global ocean surface wind products at 25 km and 50 km swath grids. Apart from this, various value added products such as (1) High Resolution Winds at 6.25 km swath grid (2) Daily Analysed Winds (3) High Resolution Sigma0 products over land and polar regions are routinely generated and disseminated to the user community through MOSDAC.

SCATSAT-1 provided invaluable wind observations during various cyclones such as Matthew, Hima, Nina, Nada, Vardha, Maarutha, Moora, Harvey and Irma etc., Apart from this, the SCATSAT-1 wind products are able to cater to various application like - improved weather forecast through data assimilation in NWP models, improved Cyclone track and intensity prediction, improved ocean state forecast through SCATSAT-1 derived wind forcing. SCATSAT-1 derived ocean surface winds are being operationally assimilated by National Centre of Medium Range Weather Forecasting (NCMRWF), MoES and Space Applications Centre, ISRO in Numerical Atmospheric Weather Prediction Model to improve the predictions. Moreover, using the SCATSAT-1 measured backscatter data, land applications like soil moisture estimation and hydrological applications such as river water level change detection studies etc., and polar studies of studying the spatio-temporal variability of Ice coverage are well demonstrated.

Analysis of SCATSAT-1 super resolution data derived sea ice had revealed that the seasonal minima of the Antarctic sea ice (occurred in the first week of March 2017) and the seasonal maxima (occurred on September 15, 2017) were delayed with respect to 2016. An animation prepared from sea ice images from January to September 15, 2017 is shown below. The sea ice derived from SCATSAT-1 is shown against the median value of sea ice extent from 1978 to 2010 (usually this is taken as climatological sea ice behaviour) is also shown. It is clear from the chart that this year the sea ice remained below normal (1981-2010 median value) for all the months.

The SCATSAT-1 data is extensively used on daily basis by both National as well as International users. It provided valuable input data to the global community in the area of weather forecasting and cyclone detection & tracking.

India plans to spend $308 million to improve weather forecasting

By Ganesh Nagarajan
India is planning to enhance its meteorological forecasting capability to more accurately predict severe weather in a localized manner.

The Ministry of Earth Sciences will send a proposal to the government for spending 20 billion rupees ($308 million) in five years to install more radars, supercomputers and special observatories, said M. Rajeevan, secretary of the ministry.

The modernization program will help the country forecast rain in a small geographical area. In August, the heaviest rainfall since 2005 killed a dozen people in Mumbai, India’s financial capital, and disrupted stock and bond trading and halted a suburban train network that carries about 8 million people a day. Local residents and civic authorities struggled to cope as most roads were submerged and commuters waded through waist-deep floodwater.

“Urban cities are a serious problem, so we are starting an urban meteorology program,” Rajeevan said in an interview in Chennai on Monday. “There are challenges in terms of predictions.”

Accurate and targeted weather forecasts are critical in India, where rain is the lifeline for about 880 million villagers who directly or indirectly depend on farming for a living. India is the world’s second-biggest grower of rice, wheat and sugar.

ISRO had succeeded in conducting the world space week celebrations as one of the biggest and popular outreach programmes of the Organisation. Important task of this programme was to inform the public about the latest advances and discoveries in the space field, application of space technologies in daily lives and to develop programmes to inspire young people to pursue careers in science and technology. In summary, through WSW-2017 events, ISRO could reach out to all the major cross section of society, made them aware of space technologies and inspired children to learn. The entire programme was very well received. The interaction with students was a great success with teachers expressing their appreciation. The exhibition and video show fascinated everyone. World Space Week activities received broad coverage by print and electronic media also.

ETS - A System for Transportation of Small Satellite and Flight Hardware
The Space programme in the country is executed through ISRO Centre/Units spread across the country, each one with a specific responsibility ranging from the conceptual design to building and operating variety of space systems. The satellites, which are built at ISRO Satellite Centre (ISAC), Bengaluru needs to be transported to the country’s spaceport at Satish Dhawan Space Centre (SDSC), Sriharikota for the launch. Towards the safe transportation of satellites, ISAC has designed and developed Satellite Transportation System (STS) and transported many satellites safely to Sriharikota.

Assembly, Integration and Testing (AIT) of satellites invariably demand safe movement of flight hardware such as equipment panels, payloads and multiple satellites (Mini/Micro/Nano) between various fabrication, integration and test facilities. Towards this, Equipment Transportation System (ETS) is designed and developed by Systems Integration Group (SIG), ISAC to adapt for varied transportation requirements of flight hardware within minimum turnaround time for modular conversion, test and validation processes. It is sized (7.88 m x 3.0 m x 3.9 m) to meet the ongoing and envisaged flight hardware of ISRO’s Space Programme.

The transportation system designed must protect the space hardware against all environment hazards encountered during transportation. The STS is built with a suspension cradle that attenuates shock, vibration and handling loads. Double walled thermally insulated, sealed encapsulation structure of STS shields satellite from climatic hazards such as temperature, humidity, contamination, rain, dust, differential pressure, etc. Robust all metallic Faraday’s cage design and low resistance electrical bonding of STS provides Electro Static Discharge (ESD) path and protection against RF radiation hazards.

In addition to these, ETS needs to be equipped with four overhead hoists (remote controlled) that operate in tandem / selected combination. The hoists powered through bus bar (Harness free) and extendable outside for handling hardware. Also, modular suspension system is tuned for low frequency range of 5-7 Hz. The intermediate berth decks permitting utility at two levels are provided. Three-way opening door enables loading operations in confined laboratories. The flexible ductings are provided for even distribution of conditioned air to control temperature and humidity. These features make the system self-contained for performing operations without depending on external handling systems, devices or accessories. Further, a low-level air suspended trailer is used to haul ETS on road.

ETS has been used for transportation of many subsystems of ISRO’s Satellites which include: Transportation of LAPT module of Chandrayaan-2 from LPSC, Bengaluru to ISAC; Transportation of 4 nos of Flight panels (GSAT-6A South Panel, GSAT-6A EV Panel, IRNSS-1I South Panel and IRNSS-1I North Panel) from ISAC to SAC, Ahmedabad. Three Panels were accommodated at the base and one panel was accommodated on the intermediate deck; Transportation of GSAT-11 EV Payload module and Feeds (4Nos) from SAC to ISAC.

ISRO is scaling up its capacity to deliver more satellites per year, channelising the support of associated centres of ISRO, Indian industries and various institutions. Towards this, ETS developed by ISAC, cater to the requirement of transporting multiple flight hardware is very useful. Transportation of multiple systems together is more economical as compared to individual transportation, resulting in reduced logistics and manpower. The response time incurred in preparation, testing, validation and certification of multiple systems has reduced significantly. ETS plays a critical role in throughput realization of multiple spacecraft which is designed in-house by ISRO and realised by harnessing the support of Indian Industry.
