So how many satellites planned in total for global range??

May be 30-35 satellites finally.

plus India shouldn't depend on foreign company about the Atomic clock.. this kind of malfunction like in 1A is costing the exchequer..

Will be developed but eventually.
Even Chinese have done it recently.

Do you know the meaning of de hyphenation?

I will come in inbox with you tonight about this that why we don't want comparisons.

I already shared my view towards the instance.
Eye closure is not the actual solution.

There are overall 81 Government space agencies around the world.
So, we can compare them on the basis of Government space agencies.

I rest my words and request for no more discussion.

May be because just around 10-15 are serving purposes out those 81 for what they were made for. Fortunately, we too are one of them.

ISRO commissions two major facilities at VSSC
ISRO today commissioned two major facilities-- a Hypersonic Wind Tunnel and Shock Tunnel-- at the Vikram Sarabhai Space Centre here as part of its continuous and concerted efforts to minimise cost of access to space.

ISRO today commissioned two major facilities-- a Hypersonic Wind Tunnel and Shock Tunnel-- at the Vikram Sarabhai Space Centre here as part of its continuous and concerted efforts to minimise cost of access to space.

ISRO Chairman Kiran Kumar said commissioning of such facilities would provide adequate data for design and development of current and future space transportation systems in the country.

He said commissioning of the facility symbolises the country's capability in establishing such world class facilities wherein technology from outside is restricted or not available.

The one meter Hypersonic Wind Tunnel and one meter Shock Tunnel have been established with a wide spectrum of simulation capabilities in terms of Mach number, Reynolds number and re-entry velocities, an official release said.

These facilities, indigenously designed, developed and 'Made in India' with the support of Indian industries, are the third largest in terms of size and simulation capability in the world, it said.

A few critical technologies, which are under embargo, have been jointly developed by ISRO and industries for realisation of these facilities.

VSSC Director Sivan in his presidential address said though excellent modeling capabilities exists with the advent of powerful computers, there was no other replacement for wind tunnel testing for aerodynamic characterisation.

The new facility would help aerodynamic characterisation of advanced space transportation systems, he said.

The facilities were dedicated in the memory of Satish Dhawan, a pioneer in the field and named as the Satish Dhawan Wind tunnel Complex.

ISRO is planning future missions such as Reusable Launch Vehicles, Two Stage to Orbit, Air Breathing propulsion systems and Human Space Flight Programme, the release added.

ISRO Joins 36th Indian Scientific Expedition to Antarctica

The National Centre for Antarctic and Ocean Research (NCAOR), Ministry of Earth Sciences, Government of India, organises the Indian Scientific Mission to Antarctica every year and ISRO has been participating for a long time. This year, in the 36th Indian scientific expedition, two teams from ISRO (one from Space Applications Centre (SAC), Ahmedabad with two members and another from National Remote Sensing Centre (NRSC), Hyderabad with four researchers) are participating.

Climate change is the thrust area of the 36th Indian Scientific Expedition to Antarctica (36-ISEA). The main objective of this expedition is to install stakes on ice for Differential Global Positioning System (DGPS) measurements around Bharati and Maitri to validate glacier surface velocity derived from satellite data to estimate thickness of snow over land and sea ice using Ground Penetrating Radars (GPR's) and also to verify conditions of snow over sea and land ice.

SAC is participating in the research activities in the area of Cryosphere under its Earth Observation Program. Cryospheric studies on the earth surface include the inventory, dynamics, changes, and interaction with hydrosphere, atmosphere etc., of snow, ice cover on land, sea ice and permafrost. The expedition team carried out helicopter based aerial surveys and collected data over the Antarctica ice-sheet, fast ice and sea ice floe. Bamboo stakes were installed over Polar Record glacier for measuring glacier surface ice velocity. The accurate coordinates of these stakes were recorded using DGPS. GPR data of various Antarctic ice features were collected at three different frequencies of 400 MHz, 500 MHz and 1GHz. It may be noted that 500 MHz GPR was indigenously developed by SAC.

Apart from collecting field data, the team at SAC also monitored sea ice status near Bharati and Maitri coasts of Antarctica using real time satellite data from newly launched SCATSAT-1 and other satellites, for accurate navigation of expedition ship.

Four researchers from NRSC are also participating in the 36-ISEA. Three of them have participated in voyage, carrying out scientific observations on board ship enrouted to Antarctica on green house gases and aerosols. The team have carried out measurements at Bharati and Maitri stations and also covering transaction between Bharati and Maitri station (about 3000 KM).

Following are the research activities in the area of climate change studies and Atmospheric studies:

• Study of snow melt/freeze dynamics in Antarctica using space based and ground based observations: Under ongoing project of NRSC, observations using snow fork were collected over six locations near Bharati station, Antarctica during November 2016 to January 2017. The observations included snow density, wetness and profile temperature in 26 pits dug on sheet ice.

• Measurements of Atmospheric Black Carbon (BC), GHGs and solar radiation fluxes at Antarctica on a long-term basis : The objectives of the project are to generate base line concentrations of atmospheric constituents such as CO2, CH4, H2O, which are being measured by ultra portable Greenhouse Gas Analyser/Licor CO2 analyser. BC measurement for long-range transport from populated mid and low latitude regions and its presence over pristine Antarctic environments is being measured using Aethalimeter-AE31. Microtops sun photometer is used to measure Columnar Aerosol Optical depth (AOD), Water vapour and Ozone.

• Image measurements of visibility to investigate atmospheric parameters : The objectives of the project are to estimate atmospheric visibility in horizontal and vertical (zenith) direction; estimation of atmospheric extinction in horizontal and vertical directions using CCD camera equipped with low power laser and laptop. CCD Camera is being used to get the contrast variation or quantifiable visibility, which in turn can be used to estimate the particulate matter over the Antarctica.

• Study on long term precipitation over Antarctica using surface and space-based measurements : The rate of atmospheric precipitation over Antarctica may have important role to global sea level variation via impact on the surface snow and ice accumulation. The objective of the project is to understand the inter-annual variability of precipitation by direct measurements of Antarctic precipitation features such as the frequency, the phase, and the snowfall rate and also validation of CloudSat satellite data retrievals of precipitation over Antarctica.

ISRO working on systems to forecast natural disasters

Indian Space Research Organisation (ISRO) is working on systems to forecast the natural disasters that could be used as input by States/disaster management agencies.
They are carrying out studies to facilitate the best use of the satellite-derived information to develop methodologies for forecasting the natural disasters.
Some of such methodologies developed include:
– Cyclone formation, track, and Intensity: ISRO has developed methodologies for forecasting the cyclone formation, its track and intensity using satellite-based observation. The methodology developed has been transferred to India meteorological Department (IMD) who is mandated for cyclone forecast.
– Flood Early Warning System: The North Eastern Space Applications Centre (NESAC) of ISRO has developed the Flood Early Warning System (FLEWS) as a Research & Development (R&D) project in Assam State in association with Assam State Disaster Management Authority (ASDMA). The FLEWS model is being used in all 25 flood prone districts of Assam. Another model for forecasting floods in Godavari floodplains in Andhra Pradesh is developed by National Remote Sensing Centre (NRSC) of ISRO. The methodology is being used by Central Water Commission (CWC). ISRO is developing similar systems for Krishna, Brahmani-Baitarani, Ghagra, Gandak, and Kosi rivers.
– Heavy Rainfall/ cloud burst alerts: Space Applications Centre (SAC) of ISRO has developed a model, for heavy rainfall/cloud burst alerts, which is being experimentally carried out for Indian region. The information is made available on ISRO’s MOSDAC (Meteorological & Oceanographic Satellite Data Archival Centre) website.
– Rainfall-triggered landslide alerts for the Uttarakhand Region: An experimental early warning system for rainfall triggered landslides is developed for use along the pilgrimage route corridors leading to Gangotri, Badrinath and Kedarnath as well as along the Pithoragarh-Malpa route in Uttarakhand. The forewarning is generated based on the statistical relation between the terrain (geological, morphological) and temporal (primarily long-term rainfall events) factors.
– Extreme weather events: ISRO has developed experimental methodologies for early warning extreme weather events such as heat wave using numerical weather predictions. The information derived is being made available on the MOSDAC website.
ISRO has realized two satellite missions, Viz., MeghaTropiques (launched in Oct 2011) and SARAL (launched in Feb 2013), in collaboration with French National Space Agency (CNES).
Presently, ISRO is working with National Aeronautics and Space Administration (NASA), the USA towards a joint realisation of a satellite mission, namely, NASA-ISRO Synthetic Aperture Radar (NISAR), to be launched by 2020-21 timeframe. The fund allocation for MeghaTropiques is Rs. 81.6 Crores, SARAL is Rs. 73.75 Crores and for NISAR is Rs. 513 Crores.
This information was provided by the Union Minister of State (Independent Charge) Development of North-Eastern Region (DoNER), MoS PMO, Personnel, Public Grievances and Pensions, Atomic Energy and Space, Dr Jitendra Singh in written reply to a question in Lok Sabha today.

Post new feat, ISRO gearing up for launch of its nextGen rocket 'GSLV MkIII'

New Delhi: After scripting history last month by launching a record set of 104 satellites using a single rocket, the Indian Space Research Organisation (ISRO) is getting ready for yet another big event – the launch of its heaviest rocket GSLV MkIII.

As per reports, the Indian space agency is preparing for two launches in the next two months from Sriharikota. One is the GSLV MkIII rocket, the next generation vehicle of ISRO, that will carry the 3.2 tonne payload, the GSAT-19 satellite.

Jitendra Singh, Minister of State in the Prime Minister's Office, told Lok Sabha that ISRO is all set to make the first developmental flight in the second quarter of 2017.

K. Sivan, Director, Vikram Sarabhai Space Centre (VSSC), Thiruvananthapuram, has earlier revealed that the space agency is planning to launch both the GSLV MkIII and GSLV MkII rockets in March and April.

On January 25, 201, ISRO successfully ground tested its indigenously developed Cryogenic Upper Stage for GSLV MkIII.

According to ISRO, the GSLV MKIII launch vehicle is capable of launching 4 ton class spacecraft in Geosynchronous Transfer Orbit (GTO). The vehicle consists of two solid strap-on motors (S200), one earth storable liquid core stage (L110) and the cryogenic stage upper stage (C25).

The GSLV MKIII is intended to launch satellites into geostationary orbit and as a launcher for an Indian crew vehicle.

ISRO set world record on February 15, 2017, for successfully launching huge number of satelites, including India's earth observation satellite Cartosat-2 series, into the polar sun synchronous orbit using its workhorse PSLV-C37 rocket, crossing another milestone in its low-cost space exploration mission.

ISRO's new feat beat the record held by Russia, which in 2014 propelled 37 satellites in a single launch. The record-breaking launch made it to the headlines of most news publications around the world, with global media hailing ISRO’s sparing, but successful space mission.

Can we use this SAARC Satellite to spy our neighbours...

This is mere a communication satellite to provide them cheap TV/Mobile Networks (and possibly some more Indian Channels).

Just in the way that Motu Patlu conquered atmi quwwat.:bounce:

You never know how things work in deep dark passage of power. Every communication satellite is in a way spy instrument. It could be used to snoop around when need rises depending on its design.

Now no country designing satellites would divulge facts like these. So better not to discuss these things..

Well, I am an IT professional who is lazy enough even to go through the forum at times.....and got this doubt.

I am sure right people at right places have definitely got this doubt for sure and made their threat perseption and might have prepared for it....And no secure communications are done through civilian communication channels....If we really need something, we can hack their computers too....

I know that spy sats are different breed when compared to com sats, their altitudes of operation, equipment are entirely different. My question is"is there a remote possibility to combine both of these sats and make a hybrid one!?"

In a way, I got the answer...

Actually its these communication satellites only which are massively used for snooping purpose. Other dedicated spy satellites are different breed and more secured. But with communication satellites like these, its upto the manufacturer and users to decide on transponders.
And in case of spying, its the innocent talks mostly which carry most of the information.

Mk3, problem is that they won't launch Mk3 before Mk2.
Though, Mk3 engine is ready for integration now.
