Exploring Orbits: Antrix Corporation

3 Years agoISRO's commercial arm Antrix has played a pivotal role in making India a launchpad for the world. Read on!

On February 15, 2017 Indian Space Research Organisation’s (ISRO) Polar Satellite Launch Vehicle (PSLV) successfully launched a record number of 104 satellites in the orbit. Along with Indian payloads, ISRO’s workhorse PSLV carried satellites of USA (96), Netherlands (1), Switzerland (1), Israel (1), Kazakhstan (1) and UAE (1) which had a combined weight of 1378 kg. With this new world record, the number of foreign satellites launched by India went up to 209 from 28 countries.1 As ISRO plans to build second vehicle assembly building, the launch capabilities of the organisation will increase to at least 12 rockets per year.2 Antrix Corporation, ISRO’s commercial arm, played an important role in negotiating launch deals from around 28 countries.3 Antrix was created to market Indian space products and services in global market. With thea creation of Antrix, India started making its presence felt in space commerce from late 1990s.4 In 2008, the company was awarded Miniratna status.

Since its inception in 1992, prestigious space agencies from Europe, North America, South East Asia and the Middle East such as European Space Agency, NASA and US Space Agency are Antrix’s clients. It also caters to globally-known space companies such as Avanti Group, World Space, Inmarsat and World Sat.5 6 In the last two years, Antrix has managed to earn foreign exchange of USD 91 Million by promoting and marketing the various products and services created by India’s space programme.7

Antrix Corporation primarily offers following services to clients:


1. Transponder Provisioning Services:

  • Antrix provides necessary space segment capacity to various satellite communication players through the Indian National Satellite System (INSAT), one of the largest domestic satellite networks in the Asia-Pacific region. There are 13 fully functional in-orbit satellites with more than 250 transponders operating at various band frequencies.8
  • Services such as Television Broadcasting (TV), Direct To Home (DTH) and Digital Satellite News Gathering (DSNG) are provided through transponders from INSAT or Geostationary Satellites (GSAT), which primarily covers the Indian subcontinent. Antrix also provides telephone services and Very Small Aperture Terminal (VSAT).9 Both GSAT and VSAT series of satellites are aimed at improving telecommunications and related services in the country.10

2. Launch services

  • ISRO’s vast experience in 63 launch missions makes it capable of providing the best mission support services.11 Antrix offers these services for customer satellites on behalf of ISRO. India’s space sector has state- of-art infrastructure for both low earth orbiting and geo-stationary satellite missions. Round-the- clock mission support is provided through Master Control Facility (MCF) and ISRO Telemetry, Tracking and Command Network (ISTRAC).12
  • Currently, Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV) are the operational launch vehicles of ISRO. The launches are executed from Satish Dhawan Space Centre (SDSC), a facility located at Sriharikota in South India.13
  • With 35 consecutive successful flights, PSLV is one of the most reliable launch vehicle with an ability to perform low inclination, Geo-synchronous Transfer Orbit (GTO) and sub-GTO missions. The launch vehicle comes with three different configurations with capacities ranging from 1,000-1,750 kg. Considered extremely reliable, PSLV was used to launch India’s Mars Orbiter Mission (MOM) on September 24, 2014.14 15 Another launch vehicle, Geosynchronous Satellite Launch Vehicle (GSLV) is a three-stage vehicle employing solid, liquid and cryogenic propulsion stages. It has had 11 successful launches till date.16

3. Remote Sensing Services

  • Antrix markets the data obtained from the constellation of Indian Remote Sensing (IRS) satellites to various domestic and international customers. The constellations of IRS satellites such as RESOURCESAT-2, CARTOSAT-1, RISAT-1 and OCEANSAT-2, constantly send data to established ground stations across the globe, which then process this data. Antrix upgrades ground systems, provides application-specific hardware and software along with turn-key solutions for receiving systems.17

4. Spacecraft, subsystems and services
