    ISRO stresses on indigenization; TRAI for Open Sky policy

    NEW DELHI: Even as he advocated an Open Sky Policy for satellites usage, Telecom Regulatory Authority of India (TRAI) chairman R S Sharma said an early formulation of a satellite communication (satcom) policy was desirable if the goals of Digital India have to be achieved.

    On the other hand, Indian Space & Research Organisation (ISRO) agreed satellite services were crucial to the success of Prime Minister Narendra Modi’s dream of Digital India, but laid stress on indigenisation to become “self-reliant” over the next few years.

    Speaking at the ‘2nd International Summit ‘India Satcom – 2016’ on the theme of Broadband for all using NextGen Satellite Technologies, TRAI’s Sharma said connectivity was vital for a digital India and satellite can help in increase this connectivity.

    That was why, he said, TRAI is in favour of an Open Sky policy and had earlier too recommended on these lines in a report to the government.

    Sharma admitted that the internet connectivity in India was barely 15 per cent, though wireless connectivity was growing at a fast pace through smart-phones. There were only 20 million phones in the country but almost the entire country was connected through mobile phones, he said.

    Suggesting use of cable and digital television systems to enable delivery of broadband, the TRAI chairman admitted that certain “policy constraints have to be crossed.”

    He said if this is not done soon, then Digital India will not move forward much.

    Referring to Ka Band on satellites, Sharma said TRAI had issued a paper in this connection in April last year.  

    While Sharma pushed for a more liberalised satcom policy to realise the dream of Digital India faster, ISRO stressed on indigenisation for self-reliance without directly dwelling on an Open Sky policy.

    In a message read out in absentia, ISRO chairman and secretary in the Department of Space A S Kiran Kumar said there was need to hold full-fledged discussions on satellite services’ contribution to Digital India and also on formulation of a satcom policy.

    He stressed that ISRO was committed to an indigenous satellite system and added more (Indian) satellites were expected to be launched over the next few years to make the country self-dependent.

    ISRO has been criticised in the past on stifling the growth of Indian users of satellite services (like DTH and VSAT operators to name a few) owing to its inability to meet the demand with supply on INSAT, while mandating time-consuming processes for Indian customers to lease capacity on foreign satellites.

    Hong Kong-based Asian industry organisation CASBAA in a recent report had highlighted how stifling satellite policies were hampering a faster rollout of a digital India.

    Titled Capacity crunch continues: Assessment of satellite transponders’ capacity for the Indian broadcast and broadband market and released in March 2016, the CASBAA-PwC report had questioned the role of ISRO and Antrix (ISRO’s commercial arm) as a satellite operator, a research institute and an independent commercial entity.

    “The roles of a policymaker and enforcer should be assigned to independent entities,” The CASBAA-PwC report stated, indicating ISRO/Antrix present roles lead to conflict of interests.

  • ISRO unites sixty space agencies to work on climate change

    ISRO unites sixty space agencies to work on climate change

    NEW DELHI: Space agencies of more than 60 countries have agreed to engage their satellites to coordinate their methods and their data to monitor human-induced greenhouse gas emissions following an initiative by the Indian Space Research Organisation (ISRO) and the French Space Agency (CNES). 

    The COP21 Climate Conference held in Paris last December acted as a wake-up call in this context. Without satellites, the reality of global warming would not have been recognised and the subsequent historic agreement at the United Nations headquarters in New York on 22 April 2016 would not have been signed. Out of the 50 essential climate variables being monitored today, 26 – including rising sea levels, sea ice extent and greenhouse gas concentrations in all layers of the atmosphere – can be measured only from space. 

    The key to effectively implementing the Paris Agreement lies in the ability to verify that nations are fulfilling their commitments to curb greenhouse gas emissions. Only satellites can do that.

    Invited to New Delhi by ISRO and CNES on 3 April 2016, the world’s space agencies decided to establish ‘an independent, international system’ to centralise data from their Earth-observing satellites through the ‘New Delhi Declaration’ that officially came into effect on 16 May 2016. 

    The goal now will be to inter-calibrate these satellite data so that they can be combined and compared over time. In other words, it is to make the transition to closely coordinated and easily accessible ‘big space data’. 

    “It is overwhelming to see the unilateral support of all space agencies to use space inputs for monitoring climate change,” said ISRO chairman A S Kiran Kumar. “Earth observation satellites provide a vital means of obtaining measurements of the climate system from a global perspective. ISRO is committed for the continuity of earth observation data, through the thematic series of satellites, with improvements en-route, to meet contemporary as well as future needs. ISRO is also engaging with CNES, JAXA and NASA for realising joint missions for global climate observation with advanced instruments.” 

    “This is a historic event that reaches far beyond the space sector and is a perfect example of the kind of success that can only be achieved through international cooperation” said CNES president Jean-Yves Le Gall. “With this consensus among space agencies from more than 60 nations, including the world’s leading space powers, the international space community and scientists now have the tools they need to put their talent, intelligence and optimism to work for the good of humankind and our planet.”

  • ISRO successfully flight tested India’s Reusable Launch Vehicle-Technology Demonstrator (RLV-TD)

    ISRO successfully flight tested India’s Reusable Launch Vehicle-Technology Demonstrator (RLV-TD)

    MUMBAI: On May 23, 2016 ISRO successfully flight tested India’s first winged body aerospace vehicle operating in hypersonic flight regime.   

    In this experimental mission, the HS9 solid rocket booster carrying RLV-TD lifted off from the First Launch Pad at Satish Dhawan Space Centre, Sriharikota at 07:00hr IST.  After a successful flight of 91.1second, HS9 burn out occurred, following which both HS9 and RLV-TD mounted on its top coasted to a height of about 56 km. At that height, RLV-TD separated from HS9 booster and further ascended to a height of about 65km.  

    From that peak altitude of 65 km, RLV-TD began its descent followed by atmospheric re-entry at around Mach 5 (five times the speed of sound). The vehicle’s Navigation, Guidance and Control system accurately steered the vehicle during this phase for safe descent. After successfully surviving a high temperatures of re-entry with the help of its Thermal Protection System (TPS), RLV-TD successfully glided down to the defined landing spot over Bay of Bengal, at a distance of about 450km from Sriharikota, thereby fulfilling its mission objectives. The vehicle was successfully tracked during its flight from ground stations at Sriharikota and a shipborne terminal. Total flight duration from launch to landing of this mission of the delta winged RLV-TD, lasted for about 770seconds.

    In this flight, critical technologies such as autonomous navigation, guidance & control, reusable thermal protection system and re-entry mission management have been successfully validated.

  • ISRO launches India’s fifth navigation satellite IRNSS-1E

    ISRO launches India’s fifth navigation satellite IRNSS-1E

    MUMBAI: The Indian Space Research Organisation’s (ISRO) Polar Satellite Launch Vehicle, PSLV-C31, successfully launched the 1425 kg IRNSS-1E, the fifth satellite in the Indian Regional Navigation Satellite System (IRNSS) on the morning of 20 January, 2016 from Satish Dhawan Space Centre SHAR, Sriharikota.

     

    This is the 32nd consecutively successful mission of PSLV and the 11th in its ‘XL’ configuration.

     

    After the PSLV-C31 lift-off at 0931 hrs (9:31 am) IST from the Second Launch Pad with the ignition of the first stage, the subsequent important flight events, namely, strap-on ignitions and separations, first stage separation, second stage ignition, heat-shield separation, second stage separation, third stage ignition and separation, fourth stage ignition and satellite injection, took place as planned. After a flight of about 18 minutes 43 seconds, IRNSS-1E Satellite was injected to an elliptical orbit of 282.4 km X 20,655.3 km inclined at an angle of 19.21 degree to the equator (very close to the intended orbit) and successfully separated from the PSLV fourth stage.

     

    After injection, the solar panels of IRNSS-1E were deployed automatically. ISRO’s Master Control Facility (at Hassan, Karnataka) took over 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 Geosynchronous Orbit at 111.75 deg East longitude with 28.1 deg inclination.

     

    IRNSS-1E is the fifth of the seven satellites constituting the space segment of the Indian Regional Navigation Satellite System. IRNSS-1A, 1B, 1C and ID, the first four satellites of the constellation, were successfully launched by PSLV on 2 July, 2013, 4 April, 2014, 16 October, 2014 and 28 March, 2015 respectively. All the four satellites are functioning satisfactorily from their designated 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 ranging and monitoring, etc., have been established in eighteen locations across the country. In the coming months, the remaining two satellites of this constellation, namely, IRNSS-1F and IG, are scheduled to be launched by PSLV, thereby completing the entire IRNSS constellation.
