Indigenous Development of 4.5 ton Vertical Planetary Mixer

Indian Space Research Organisation (ISRO) uses solid motors of 139 ton capacity for PSLV/GSLV flights and 200 ton capacity for the GSLV Mk III flights as part of their first stage. These motors are produced in the indigenously developed Solid Propellant Plants of ISRO at Satish Dhawan Space Centre SHAR, Srihairkota.
Propellant mixing is one of the critical processes in the solid propellant manufacturing where different solid ingredients are mixed with binder in a vertical planetary mixer to achieve required homogeneity and viscosity. The propellant slurry is highly viscous semi-solid and less than 5% co-efficient of variation (COV) needs to be achieved for the homogeneity.
ISRO was importing planetary mixers of 2.5 ton capacity during 1980’s. Initially, M/s. Central Manufacturing Technology Institute (CMTI), Bengaluru, had developed the 2.5 ton capacity mixer as per the requirements of ISRO. So far, six mixers were built by M/s CMTI and supplied to ISRO. Subsequently, M/s.CMTI, has developed the 4.5 ton mixer by suitably scaling up the design parameters of 2.5 ton vertical mixer.
The 4.5 ton Mixer consists of two outer agitators and one centre agitator. The planetary motion to the outer agitators guarantees that the whole volume of the bowl is swept without leaving any dead zones. The lateral surface of the mixer blades is helical thus ensuring good pumping capability. The major challenges for mixer development are: a) Uniform homogenisation of mixing with less than 5% variation; b)Sizing of the agitators with 6 to 7 mm gap; c) Low speed and high torque hydro motor to drive the mixer for mixing high viscous fluids; d) Operating speeds for agitators varying from 2 to 8 RPM; e) Selection and sizing the gear box for achieving the reduction ratios.
The mixer system is facilitated by other subsystems like feeding system, propellant slurry temperature control system, PLC based control system, compressed air system for operating the bowl, spill tray collection system for collecting the remnant propellant on the agitators and bowl lid lifting system.
Safety is the prime criteria for the mixers deployed for the mixing of hazardous, explosive material like solid propellant. The mixer has been designed and provided with over load protection devices in gearboxes to protect from the overload during charging of powders and unusual viscosity build up during mixing operations. The mixer is also provided with automatic bowl drop mechanism in bowl lift hydraulic circuit to relieve the unusual pressure build up during mixing operations.
Very elaborate process and quality plans have been prepared for the realisation of the components. Many technical challenges were faced during the realisation of some of the critical components. All the critical elements like mixer blades, mixer central agitator shaft for mounting the mixer central agitator, mixer bowls (stainless steel mixer bowl of 2050 mm x 1350 mm depth and shell thickness of 35 mm, weighing 9 tons), etc., are realised with dedicated team effort of SDSC SHAR and CMTI Engineers.
After realisation of the subsystems, M/s. CMTI successfully completed shop floor integration of all subsystems and demonstrated the basic functions of the vertical mixer. The vertical mixer was then moved and commissioned at SDSC SHAR, Sriharikota. A detailed test and evaluation procedure was established and executed towards final commissioning of the first indigenously developed 4.5 ton vertical mixer. Chairman ISRO inaugurated this facility recently.
The realisation of this critical technological challenging high capacity vertical mixer has paved way for increasing the throughput of the plant and also reducing variations in processing, thus improving the overall product quality. This has given a major impetus to the indigenisation efforts of ISRO in space activities.

When is GSLV mk3 launch?
20th January, interestingly, PSLV C-37 carrying 80+ satellites is scheduled just 7 days later on January 27th.
If it goes, ISRO will break it's own record of turnaround time between two launches for 18 days (between PSLV C-35 and GSLV D6 in August September) to just 7 day.
It's possible because ISRO has started utilizing both pads more equally in recent days.

Issues request for proposal for two-year hire
A chronic national shortage of communication satellite capacity has forced the Indian Space Research Organisation (ISRO) to search for a quick-fix lease of an overseas satellite in orbit, temporarily.

ISRO routinely leases partial capacity on foreign satellites, primarily for the bulk of private direct-to-home television operators. However, it has not leased an entire communication satellite. The space agency says it needs to hire a suitable extra spacecraft for two or three years. It put out an RFP (request for proposal) earlier in December asking international satellite operators if they can spare an existing geostationary spacecraft; or one that will be launched in the first quarter of 2017.

Post-deal, the satellite which must also have Ku-band transponders will be moved into one of the six satellite parking slots allotted to India overhead within its longitudes.

The lease will temporarily augment ISRO's transponder capacity for various national uses, A.S. Kiran Kumar, ISRO Chairman and Secretary, Department of Space, told The Hindu recently, adding that there was no emergency in the sky. The leasing process may take a few months.

ISRO has about a dozen communication satellites in orbit. As per a 2015 estimate, a third of the 286 satellite transponders in use was non-Indian.

In addition to the lease plan, Mr. Kiran Kumar said, “We are putting up five new communication satellites during 2017. This should significantly improve our capacity.”

Among the upcoming satellites is a bigger spacecraft which will be the first Indian high-throughput satellite (HTS) targeted at increasing the connectivity for Internet users.

ISRO’s previous communication satellite was launched in October. Mr. Kiran Kumar, who also chairs the Space Commission, said, “With the launch of GSAT-18, we have almost 48 additional transponders coming up for use.”

The Asian region has a very dense population of commercial satellites over its skies and ISRO has time and again borrowed space on spacecraft of Malaysian, Thai, Singapore and U.S. operators.

When its communication satellite INSAT-2D died prematurely a few months after launch in 1997, ISRO bought the entire Arabsat-1C from Saudi Arabia in orbit to bridge the shortage.

The space agency plans to double the number of launches to 12-18 a year. Mr. Kiran Kumar had said in September that ISRO needs to at least double the number of spacecraft that it has in order “to give reasonable service” to the country. At least 60 government departments and a number of commercial entities depend on Indian satellite data for communication, broadcasting, defence, weather forecasting, rescue during disasters, natural resources management and Earth observation.

Centre launches IVRS platform to address the problem of call drops



Department of Telecommunications (DoT) has been taking various initiatives to address the problem of call drops faced by subscribers in mobile networks. The Telecom Service Providers (TSPs) have installed more than 1,30,000 additional BTSs (Base Transceiver Stations) across the country during the period from June 2016 to October 2016 and further plan to install more than 1,50,000 additional BTSs across the country up to 31st March 2017.

In order to obtain direct feedback from subscribers and use that feedback to solve the problem of call drops, DoT has launched an Integrated Voice Response System (IVRS) system in Delhi, Mumbai, Punjab, UP, Uttarakhand, Maharashtra and Goa on 23rd December 2016. The IVRS system will be extended to the entire country very soon.

Subscribers will receive an IVRS call from the short code 1955. They will be asked a few questions on the subject of call drops such as- “Are they facing call drops in their area or not? They can also send a toll-free SMS to the same short code 1955, containing the location of city/town/village, where they might be facing the problem of frequent call drops. The feedback of the subscribers will be shared with the Telecom Service Providers so that they can take corrective steps in the identified areas, to improve the mobile network for addressing the problem of call drops.

Minister of Communications Shri Manoj Sinha said that “the platform is a channel to capture direct feedback from the consumers and this voice of the customer can be used to improve the services that are being offered to them”. He said, initially the government will use the platform for call drops and will extend this to capture consumer feedback in other areas as well in the future.

Year End review: Department of Space

An unprecedented seven missions launched, all successful

Successful maiden test flights of Reusable Launch Vehicle and SCRAMJET



The year 2016 was very eventful for the Indian space programme which scored very prominent and significant successes in launch vehicle, satellite, applications and space exploration domains. The year saw an unprecedented seven launch vehicle missions all of which were successful. Eight ISRO satellites, four student satellites and 22 foreign satellites were launched by these missions. The year 2016 also saw two successful advanced launch vehicle technology initiatives of ISRO – the Reusable Launch Vehicle-Technology Demonstrator (RLV-TD) and SCRAMJET technology demonstrator – which had their maiden test flights. Additionally, the highly successful Mars Orbiter Spacecraft of India completed two years in its orbit around Mars and India's ASTROSAT multi-wavelength observatory successfully completed one year in orbit.

Launch Vehicle and Satellite Missions of ISRO:

1.1. PSLV-C31/IRNSS-1E Mission: In this flight, the workhorse launch vehicle PSLV launched IRNSS-1E, the fifth satellite of the Indian Regional Navigational Satellite System (IRNSS) constellation, on January 20, 2016.

1.2. PSLV-C32/IRNSS-1F Mission: In this flight, which was its 34th, PSLV launched IRNSS-1F, the sixth satellite of the Indian Regional Navigational Satellite System (IRNSS) constellation, on March 10, 2016.

1.3. PSLV-C33/IRNSS-1G Mission: In this flight, PSLV launched the seventh and the last satellite IRNSS-1G of the Indian Regional Navigational Satellite System (IRNSS) constellation on April 28, 2016. With this, the space segment of the IRNSS is fully deployed. IRNSS signals are now available and trials with the receiver system are in progress. The Prime Minister Shri Narendra Modi dedicated IRNSS to the nation as ‘NavIC’ (Navigation Indian Constellation). This is an independent regional navigation satellite system designed to provide position information in the Indian region and 1500 km around the Indian mainland. IRNSS provides two types of services, namely, Standard Positioning Services (SPS) - provided to all users and Restricted Services (RS) - provided to authorised users only.

1.4. Reusable Launch Vehicle – Technology Demonstrator (RLV-TD): India’s first winged body aerospace vehicle, RLV-TD i.e. Reusable Launch Vehicle-Technology Demonstrator (RLV-TD), was successfully flight tested on May 23, 2016. From the 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). After successfully surviving a high temperature of re-entry, RLV-TD successfully glided down to the defined landing spot over Bay of Bengal. In this flight, critical technologies such as autonomous navigation, guidance & control, reusable thermal protection system and re-entry mission management were successfully validated.

1.5. PSLV-C34/Cartosat-2 Series Mission: On June 22, 2016, PSLV-C34 successfully launched 20 satellites in a single mission. It included India’s CARTOSAT-2 series of satellite (weighing 727 kg) as primary payload and two academic institutes’ satellites, namely, SWAYAM and SATHYABAMASAT and 17 satellites (total weighing 555 kg) of foreign customers from Canada, Germany, Indonesia and USA as co-passengers.

1.6. GSLV-F05/ INSAT-3DR Mission: On September 08, 2016, GSLV-F05, India's Geosynchronous Satellite Launch Vehicle, equipped with the indigenous Cryogenic Upper Stage (CUS), successfully launched the country's weather satellite INSAT-3DR. INSAT-3DR is a follow-on meteorological satellite to INSAT-3D. This launch is significant, considering that fact that this is the third consecutive success of the indigenous CUS, which signified the country’s successful assimilation of the complex cryogenic rocket propulsion.

The satellite carries two meteorological payloads, viz., 6 channel imager & 19 channel sounder. It also carries a Data Relay Transponder (DRT) and Satellite Aided Search and Rescue (SA&R) payload to provide continuity to INSAT SA&R services. The satellite has started providing services to the weather and meteorological community in tandem with INSAT 3D that is already in the orbit. By virtue of these 2 satellites in orbit, the country gets weather updates every 15 minutes which is yet another unique service from space.

1.7. Successful Flight Testing of ISRO's Scramjet Engine Technology Demonstrator: The first experimental mission of ISRO’s Scramjet Engine towards the realisation of an Air Breathing Propulsion System was successfully conducted on August 28, 2016 from Satish Dhawan Space Centre SHAR, Sriharikota. The Scramjet engine designed by ISRO uses Hydrogen as fuel and the Oxygen from the atmospheric air as the oxidiser. This marked the maiden short duration experimental test of ISRO’s Scramjet engine with a hypersonic flight at Mach 6. ISRO’s Advanced Technology Vehicle (ATV), which is an advanced sounding rocket, was the solid rocket booster used for the test of Scramjet engines at supersonic conditions. ATV carrying Scramjet engines weighed 3277 kg at lift-off.

India is the fourth country to demonstrate the flight testing of Scramjet Engine. The successful technology demonstration of air-breathing Scramjet engines in flight by ISRO during the year was a modest yet important milestone in its endeavour to design and develop advanced air breathing engines including engines for ISRO’s future space transportation system

2. PSLV-C35/SCATSAT-1: By successfully launching SCATSAT-1 satellite carrying a scatterometer for wind vector measurement into the required polar Sun Synchronous Orbit in its PSLV-C35 mission on September 26, 2016, the PSLV facilitated continuity to Oceansat-2 Scatterometer, which completed its service in March 2014. The wind vector at sea surface information facilitated by SCATSAT-1 is used in weather prediction models and helps in accurate prediction of cyclone track. This launch of PSLV had yet another unique achievement of placing satellites in 2 different orbits and also the longest of the missions that lasted for more than 2 hrs 15 mins after lift-off. In this mission, engine multiple restart experiment of upper stage of PSLV was also demonstrated.

2.1. PSLV-C36/Resourcesat-2A: In its 38th flight, PSLV successfully launched RESOURCESAT-2A satellite on December 07, 2016 into an 822 km polar Sun Synchronous Orbit. This was PSLV’s 37th consecutive success. The 1235 kg RESOURCESAT-2A is a follow on mission to Resourcesat-2 and intended to ensure data continuity to the users for land and water resources applications. The satellite is configured with three-tier imaging capability consisting of three solid-state cameras, viz., LISS-IV, LISS-III and an Advanced Wide Field Sensor (AWiFS).

2.2. GSAT-18: The 3405 kg communication satellite GSAT-18, launched on October 06, 2016 by European Ariane V, carries a total of 48 transponders in Ku-band, C-band and Ext C-band for providing continuity of services and has further augmented the transponder capacity.

3. Disaster Management Support (DMS):

3.1. Uttarakhand Forest Fire: The Uttarakhand state witnessed episodic fire incidents during the last two weeks of April 2016. Recurrence of fire incidences is common in the hilly state in summer season. Satellite data based temperature anomalies were used for the detection of active fire locations. About 1600 active forest fire locations were recorded during 24th April to 4th May 2016. The burnt area was also assessed using Satellite data. The information on a near-real time basis was disseminated to Forest Survey of India, State Forest Departments, NDMA and SMS on fire alerts were sent to the identified forest officials of Uttarakhand. All Fire alerts were also published on BHUVAN geoportal. The most affected districts were Nainital, Pithoragarh, Champawat, Almora, Pauri and Tehri Garhwal.

3.2. Floods occurred in Assam and Manipur states during 2016. Three waves of floods were reported in Assam; first during fourth week of April, 2016, second on 21st June, 2016 and third on 4th July, 2016. Lakhimpur, Jorhat, Sibsagar, Charaideo, Dhemaji and Karbi Anglong districts were affected. Heavy pre-monsoon rains lashed Manipur during the last week of April 2016 and Imphal, Thoubal and Bishnupur districts were reported to be affected. The information on flood inundation was disseminated to the Central and respective State Government departments, State Relief Commissioners and nodal Ministries.

4. Mars Orbiter Mission: India’s first inter-planetary mission completed two years in its orbit around Mars. The health parameters of Mars Orbiter spacecraft are normal and all the five payloads are sending useful data. The Mars Colour Camera has produced more than 530 images so far, one of which has appeared on the cover page of the November 2016 issue of the National Geographic Magazine. The spacecraft successfully negotiated ‘whiteout’ geometry during May 18 - 30, 2016 using onboard autonomy. The archived data is now made public for free download and scientific research through ISRO’s website. More than 1.75 Lakh hits and about 40 GB data was downloaded in just 2 weeks. ISRO has also launched MOM Announcement of Opportunity (AO) programmes for researchers in the country to use the MOM data for R&D. The success of Mars Orbiter Mission has showcased India’s technical capability in exploring planetary bodies and has motivated India’s student and research community in a big way.

5. ASTROSAT Mission: ASTROSAT, India’s first multi-wavelength observatory has completed one year in orbit as of September 2016. An Announcement of Opportunity (AO) was made in June 2016 for Indian researchers to explore the universe using data from ASTROSAT. As a part of one year completion of ASTROSAT in orbit, a one-day workshop was organised at Inter-University Centre for Astronomy and Astrophysics (IUCAA), Pune on Sept 29, 2016, to highlight the technical and scientific achievements of this satellite. The first scientific set of results and the future scope of the satellite were presented during the meeting.

6. Space technology based tools in Governance & Development: Space technology applications, derived through synergistic use of earth observation, communication & navigation satellites and complemented with ground-based observations, play a key role in harnessing the benefits of space technology for socio-economic development in the country and improving the quality of life of citizens.

Satellite-based Earth Observation is a cost effective means of obtaining essential and reliable data on our Earth. Such data on natural resources have become an integral part of planning and implementation of action plans for managing land & water resources, developing urban & rural infrastructure, monitoring weather & climate, protecting environment including disaster risk reduction. The capabilities of satellite communication are also exploited for delivering societal applications towards education & health, connectivity, skill development and livelihood sustenance. Space technology-based applications & tools are being increasingly used in governance and development for enabling planning, periodic monitoring, mid-course correction, evaluation of developmental activities and scientific decision making in various sectors right from agriculture, urban & rural planning to disaster risk reduction.

Department of Space is working closely with various Central Ministries/Departments and State Governments towards maximizing the use of space technology in the various areas viz. Natural Resources Management, Energy & Infrastructure, Disaster & Early Warning, Communication & Navigation, e-Governance & Geo-spatial Governance and Societal Services. Many flagship programmes namely, Atal Mission for Rejuvenation & Urban Transformation; Pradhan Mantri Awas Yojana; Pradhan Mantri Krishi Sinchayee Yojana; National Mission for Clean Ganga, Digital India & MGNREGA are also utilizing space-based tools.

ISRO is focusing on providing assured services through data continuity, improved connectivity & location-based services and enabling proactive user engagement through institutionalisation of space applications and capacity building. In a nutshell, ISRO is enabling the space applications in tune with the requirements of Ministries/Departments to enhance functional effectiveness, facilitate planning and decision making to improve governance and development.

7. Follow-up Actions on National Meet for Application of Space Technology & Tools: Out of the 160 projects emerged as an outcome of the national meet, work was initiated in 144 projects. In about 60 projects, significant progress has been made in terms of development of methodology, web and mobile applications, training and execution of work. About 75 customised web applications and 50 mobile applications were deployed. MoUs were signed with Central Ministries/Departments as well as the State Governments. Based on the request of the Ministries/ Departments for capacity building, more than 9,000 officials were trained. Additionally, Outreach programmes were also conducted in Colleges and Schools. State Meets on ‘Promoting space technology -based tools’ were completed for many States.
