International Ground Segment (IGS) Services
Overview
NRSC has wealth of images from Indian and foreign remote sensing satellites in its archives. It also has the capability to acquire data pertaining to any part of the globe on demand. NRSC has been instrumental in promoting IRS data for International users and agencies by providing data and technical services. NRSC also enables ANTRIX, the commercial and marketing arm of ISRO, to execute various remote sensing services for International Customers worldwide.
Data Acquisition & Processing Support : Providing turnkey solutions by establishment of ground segment systems from Planning, Antenna systems, direct data receiving, processing and catalogue generation.
Establishment of Virtual ground Station (VGS). Setting up Virtual ground stations (VGS). Providing users near real-time, full resolution RAW satellite data using ISRO's own constellation of ground stations for generating data products locally at the user's site

Calibration Services
National Remote Sensing Center(NRSC)/ISRO has established and operationalised an unique Cal-Val facility in IMGEOS Complex at Shadnagar, Hyderabad to enable the calibration needs of Optical and Microwave sensors.
It has built the technical competence to collaborate for the Calibration of foreign remote sensing sensors.
The facility is designed to perform the radiometric calibration of high resolution multispectral data (better than 10m) at 5 different radiometric levels from 7% to 50% reflectance levels simultaneously and mid resolution data ( better than 25m) at two different levels 7% and 30% in the VNIR & SWIR spectral bands. The five targets are developed using natural materials of stone and soil and they well maintained for the spatial/temporal stability during the favourable period of October to May.
NRSC has also established a microwave calibration site consisting of corner reflectors in a 200m x 80m area to conduct SAR calibration exercises for present and future Space borne and Airborne SAR missions to support calibration activities during the commissioning and operational phase . Ample care has been taken to maintain calibration site in vegetation free condition with low background level which is an important factor for absolute radiometric calibration.

Satellite Ground Station Services
The department of Space can establish antenna systems for receiving remote sensing satellite data at S and X band for Indian and foreign users subject to approval of IN-SPACe.
Indian remote sensing satellite program has witnessed rapid technological advancement both on space and ground segments in the last few decades. With the emerging high-resolution satellite programs with increased data rates from 10 Mbps to 960 Mbps, the role of ground station has become more critical. Keeping in view of these challenges, NRSC designed and developed an S/X band dual polarization 7.5M antenna system to meet the current and future Earth observation mission requirements.
While DoSdevelop and install a 7.5M S/X band antenna system as a new ground station. The following inputs are required.

Satellite mission operation has different phase like, prelaunch, initial phase, normal phase, contingencies phase and decommissioning phase. During each phase different sequence of activity needs to be performed to ensure proper function of the satellite throughout its mission life.
Also, Satellite mission operation needs multiple software tools to handle the mission scenario.
Visibility Analysis for Ground stations planning
Station co-ordinates selection and their Visibility Analysis based on launch events and vehicle trajectory
Useful inlaunch vehicle activities to deploy network of stations to track, monitor the launch vehicle and spacecraft during the launch phase and mission planning.
Ground Station Antenna Angle Calibration
Provides Telemetry Tracking, Commanding station Antenna angle calibration for the ground stations
engaged either for launch vehicle tracking during the launch or for spacecraft tracking to meet the pointing accuracy
Telemetry Tracking, Commanding ground station antenna pointing accuracy is very much essential for tracking either launch vehicle/rocket or spacecraft object. This service is useful for Users involved in precise tracking of either launch vehicle or spacecraft accounting azimuth and elevation biases through the antennae angles calibration campaign phase
