Abstract of Speech

Antrix Corporation Limited (Antrix), the commercial arm of Indian Space Research Organisation (ISRO), was created with the objective of promotion and commercial exploitation of space products and services, nationally and internationally. Earth Observation (EO) or Remote Sensing (RS) data fall into two distinct categories, the first one is coarse and medium resolution data, which have immense value for earth system studies and management of ecosystems and the other, is high and very high resolution data. Since its formation in 1992, Antrixhas been striving to utilize the spare capacity available with the IRS satellites for global user requirements. During 1994, the International Ground Station (IGS) for IRS Satellite was established at Normal, Oklahoma. The number then increased to about 20 IGS stations by 2010, providing coarse, medium and high resolution data for land and ocean applications. With increased number of players in EO data market, the segment has become Buyers’ market and new Business Models are being worked out by established players to sustain in the market. With the increased supply of imagery, there is a need to define the standards for the satellite imagery so that interoperability of data sets improves, which would help in providing value added services on an operational basis without any discontinuity. Antrix, using the spare capacity available with PSLV, ISRO’s workhouse launch vehicle, has launched 239 satellites belonging to 29 countries. Antrix also provides TTC services to the customer satellites using ISRO’s network of stations. Antrix believes in increased business cooperation by mutual access to each other capability, capacity and resources to reap the benefits of the Space technology.
