              INTRODUCTION
Indian Space Programme is an Indigenous Effort with a
capability to provide various socio-economic developmental
applications.
The role has been to develop space-technology, system
management and new applications that relevant for India.
INSAT system has been established for communication,
broadcasting and meteorology.
The Indian remote sensing satellite system has been established
for resource survey management.
India has also acquired capability to launch satellites into Polar
as well as Geo-Synchronous satellite orbits through PSLV and
GSLV launchers respectively.

India has a fleet of satellites operating in S-Band, C-Band,
Ext C- Band and Ku Band for various applications.
The GSAT series of satellites are built and launched for
technology demonstration, validation to prove the
technologies before using them in operational INSATs.

  Future Satellite Communications
India is planning to have high
power Ku band satellite for
broadband multimedia
communication.

Programme is on an advanced
communication satellite to meet
new applications.

A dedicated satellite for formal as
well as informal education is
being envisaged
          INDUSTRY PARTICIPATION

• Over the years considerable infrastructure and expertise is
  developed within the Indian hi-tech industries to provide
  support to space missions (satellite and launch vehicles).
• The structural hardware of communication satellite is
  produced at Hindustan Aeronautics Ltd (HAL) which is one of
  the leading aerospace industry in the Asia pacific region. All
  the satellite structures since the experimental phase to the
  present operational era are produced at HAL.
• The satellite propulsion systems are largely taken from
  production capability of BHEL, HAL and other private sector
  industrial giants like L&T, Godrej and MTAR.
          INDUSTRY PARTICIPATION (2)


• The communication payload and its components are normally
  made at the electronicsdivision of HAL, Hyderabad, BHEL
  Bangalore and Ghaziabad and also at a number of small to
  medium scale private enterprises.
• The applications specific integrated circuits (ASICs), hybrid micro
  circuits (HMCs) and printed circuit boards are routinely produced
  to space quality requirements at hi-tech industries like WIE Poona,
  HAL Hyderabad, MICROPAK Bangalore and at leading boundaries
  in Europe, as per our design.
• Solar array, battery assemblies are fabricated utilising the
  production capacities at BHEL Bangalore and some local private
  enterprises.
FACILITIES - Thermovacuum Chamber
FACILITIES - Clean Room
                 NEW FACILITIES

• High Power Test Lab established for High Power component
  characterization at S, C, & Ku-Bands
   – Peak power generation for multipactor test.
   – RF high power handling test in thermal vacuum.
   – PIM test

• New AIT complex for ensuring smooth flow of spacecraft
  level activities. This complex consists of
   – a clean room for spacecraft assembly & test activities
     measuring 55m x 34m x 15m
   – an anechoic chamber measuring 20m x 15m x 15m
   – a thermovac chamber of 6.5m dia
                 NEW FACILITIES (2)

• Compact Range Test Facility for antenna testing has been
  established for unit level antenna test at SAC, Ahmedabad.
  The fully equipped compact range is capable of
  characterizing antennas from S-band to 40GHz.

• A similar facility for spacecraft level test is under
