Data reception & dissemination

National Remote Sensing Centre (NRSC) is responsible for remote sensing satellite data acquisition and processing, data dissemination, aerial remote sensing and decision support for disaster management.

NRSC has archived a prosperity of satellite images from Indian and foreign satellites since 1983. NRSC has its data reception facility at Shadnagar, 65 km from Hyderabad city. The station has four state of the art antenna systems for data reception and archival.

The Satellite data processing chain has a user friendly web mechanism to enable users to order data of their requirement. It can facilitate to acquire data pertaining to any part of the globe on user request.

The Aerial facility has two Beech craft aircraft to acquire data utilizing various sensors like Aerial cameras, Laser instrument, Synthetic aperture radar and Magnetometer. The aerial facility has carried out number of studies for mapping and infrastructure planning for towns and cities, Cadastral surveys, canal alignment for interlinking of rivers, Digital elevation model (DEM) applications , Mineral targeting etc., It has also carried out international projects in Maldives & Emirates of Dubai.

The Decision Support Centre (DSC) is a single window information provider on major natural disasters like Floods, Agricultural Drought, and Forest fires, Cyclones, Earthquakes and Landslides.

It provides near real time information to State and Central government for relief, rehabilitation and planning. The DSC also supports International Charter on Space and Major Disasters and Sentinel Asia. Under this, critical support was extended to Myanmar during Nargis (2008) Cyclone; Indonesian floods (2008) and China earthquake (2008).

NRSC also has very sophisticated infrastructure for analysis of satellite data: state-of-art Digital image processing and GIS Lab.

About Data Analysis

Remote sensing data are being used to map/monitor/survey/manage various natural resources of the country under National Natural Resources Management System (NNRMS) programmes. Funded by various user ministries and ISRO/DOS, these programmes have been generating valuable spatial data assets and information solutions.

Several areas of application such as Agriculture, Soil, Bio-resources and Environment, Ocean Resources, Water Resources, Rural Development, Urban Development, and Disaster Management etc., which are of direct consequence to the nation are executed by ISRO/DOS centers like National Remote Sensing Centre (NRSC), Space Application Centre (SAC), Regional Remote Sensing Service Centres (RRSSCs), North Eastern - Space Application Centre (NE - SAC) and State Remote Sensing Centers and State/Central Agencies.

Five were set up in Bangalore, Dehra Dun, Jodhpur, Kharagpur and Nagpur support the various remote sensing tasks specific to their regions as well as at the national level. A separate Space Center with both Remote Sensing and Communication facilities has been set up in the northeastern part of the country.

These centers have sophisticated computer facilities for image analysis and GIS to cater to the user’s needs and participate actively in areas like disaster management, software development, agro-climatic planning, national drinking water mission, national resources census, large scale mapping, etc, besides taking up projects for various ministries and departments.

About Tracking Facility

ISRO Telemetry, Tracking and Command Network (ISTRAC) provide mission support to low-earth orbit satellites as well as launch vehicle missions. ISTRAC has its headquarters and a multi-mission spaceship Control Centre at Bangalore. It has a network of ground stations at Bangalore, Luck now, Sriharikota, Port Blair and Thiruvananthapuram in India besides stations at Mauritius, Bearslake (Russia), Brunei and Biak (Indonesia).

ISTRAC activities are organized into network operations, network augmentation, mission operation and spacecraft health monitoring, communications and computers and control centre facilities and development projects. Programme planning and reliability groups support ISTRAC activities.

The Indian Deep Space Network (IDSN), commissioned during the year 2008, at Byalalu village near Bangalore forms the Ground segment for providing deep space support for India's prestigious and first Lunar mission, the Chandrayaan-1.The technical facilities in IDSN include a 32 meter Deep Space Antenna, an 18 meter Antenna Terminal, an 11 meter Antenna Terminal, Indian Space Science Data Centre (ISSDC) and a Technical Services complex.

The IDSN is the first of its kind project in the country that provides ISRO the capability to handle deep space missions of India and also provides cross support to other deep space missions of exterior space agencies because of its inter-operable features and state-of-the-art capabilities.
