- Abstract
Global Geospatial market has been expanding over the years. While the number of service providers in the value addition, software and solutions have multiplied in number, the number of space based remote sensing data providers has been confined to handful of agencies and notable among them is the Indian space agency, ISRO. With a systematic development and long range planning, Indian Space Programme has contributed to the wealth of space based platforms for Earth Observation (EO). IRS satllites, ISRO’s EO Missions, born local to meet the national needs have grown global with commercialisation and international distribution by Antrix Corporation Limited, the Marketing arm of ISRO. While the first satellite IRS-1A has served national, the launch of IRS-1B has seen the advent of commercialisation. This, followed by the improved twin satellites IRS-1C and IRS-1D have paved the proved IRS’s significant role in the global Geospatial market with the number of International Stations receiving the IRS data touching a peak of 20 at one time. Antrix Corporation Limited, the commercial and marketing arm of ISRO brings these services to the international customers. High Resolution missions by commercial companies like IKONOS of Space Imaging and QuickBird of Digital Globe have propelled the ever increasing data demands higher. Still there exists a demand for more reliable and more accurate inputs for decision making in the context of mitigation and management of disasters, both natural and man made. Many countries are joining this group with their own high resolution satellites. India’s Resourcesat-1 is a unique satellite offering data with three different resolutions and four different swaths with a revisit of 5 days to address some of these needs. ISRO’s CARTOSAT-1 with 2.5 along track stereo data capability, is a customer centric mission set to drive the market towards new applications. The availability of a constellation with multiple temporal, spatial and spectral resolutions by a single operator is the strength of IRS making it possible to meet the varying requirements for civilian and security needs. A host of new optical satellites with resolution improved to 1m (from the recently launched Cartosat-2) and a C-band SAR payload (RISAT); in additional to cooperative missions planned with international partners are expected to uphold the global customers’ confidence in ISRO/Antrix as a long term and reliable service provider.
