The Indian Institute of Space Science and Technology (IIST), a Deemed
to be University under Section 3 of the UGC Act 1956, was set up under
the Department of Space, Government of India in the academic year,
200708. The Institute now offers undergraduate (B Tech) programmes in
Aerospace Engineering, Avionics, and Physical Sciences.
All questions will be of objective type and will consist of three separate sections in Physics, Chemistry and Mathematics.
Aerospace Engineering: B.Tech in Aerospace Engineering programme
is similar to programmes with identical title offered by many reputed
Institutions in India and abroad. The programme in IIST is oriented
towards the needs of space technology, and has significant overlap with
Mechanical Engineering including Mechanical Design and Manufacturing
Science and Space Dynamics. People with B.Tech Degree in Aerospace
Engineering can further specialize in Flight Mechanics, Aerodynamics,
Thermal and Propulsion, Structure and Design and Manufacturing Science.
Avionics: Avionics means electronics used in aerospace systems.
The students get to learn what is generally covered in a typical
Electronics and Communications programme and in addition, get exposure
to Advanced Electronics in digital and communication, control systems
and computer systems used in aerospace systems. People with B. Tech
Avionics Degree can later specialize in areas like DSP, RF &
Communication, Antenna, Power electronics, micro electronics, control
system etc.
Physical Sciences: B. Tech in Physical Sciences is oriented
towards application of basic sciences in Space Science, Space
Technology and Space Application. The programme lays a strong
foundation in Physics, Chemistry, and Mathematics and gives exposure to
important applications of space technology such as Remote Sensing and
GIS, Astronomy and Astrophysics, and Earth System Sciences. People with
B. Tech Degree in Physical Science can later specialize in areas like
Atmospheric and Ocean Sciences, Solid Earth Science, Astronomy and
Astrophysics, Remote Sensing & GIS, and Chemical Systems. The
curriculum will have the best blend of basic science and engineering.
Every student who completes the B.Tech programme of IIST, meeting
specified academic standards, will be absorbed in ISRO as
Scientist/Engineer SC. To be thus eligible for absorption in ISRO, the
student should have completed the B.Tech programme in four years with a
minimum Cumulative Grade Point Average (CGPA) of 6.5 (out of a maximum
of 10). Students who join IIST to pursue Undergraduate programme are
required to furnish a bond to serve ISRO for five years immediately
after completion of the programme. The maximum time limit allowed for
successful completion of the programme is six years, but any extension
beyond the normal four years renders the student ineligible for
absorption in ISRO.
Correct answers will be awarded three marks each. Every incorrect answer will be awarded one negative mark.
Candidates must make sure that they satisfy all the eligibility conditions given below for appearing in ISAT2010:
 Citizenship
Only Indian citizens are eligible to appear in ISAT2010.  Date of Birth
The date of birth of candidates belonging to GEN and OBC categories
should be on or after October 1, 1985, while the date of birth of those
belonging to SC, ST and PD categories should be on or after October 1,
1980.
The date of birth as recorded in the high school/first Board /or its
equivalent will be accepted. If the certificate does not mention the
date of birth, candidate must submit at the time of Counselling an
authenticated document from competent authority indicating the date of
birth.
 Qualifying Examination (QE)
A candidate must have passed the QE for the first time, in the calendar
year 2009 or 2010, provided the results are available before 1 July
2010. Those who are expecting the results of QE later than July 1, 2010
are not eligible to apply for ISAT2010.
The qualifying examinations are listed below:
 The final examination of the 10+2 system, conducted by any
recognized Central / State
Board, such as Central Board of Secondary Education, New Delhi; Council
for Indian School Certificate Examination, New Delhi, etc.
 Intermediate or twoyear PreUniversity examination conducted by a recognized Board / University.
 Final examination of the twoyear course of the Joint Services Wing of the National Defence Academy.

70% in aggregate in Physics, Chemistry and Mathematics (PCM) papers and
those belonging to SC, ST and PD categories must have at least 60%.
 For both Class X and 10 +2 examinations, the percentage of marks
awarded by the Board will be treated as final. If the Board provides
the equivalent percentage of marks against grades, then the candidate
has to base his/her calculations in percentage. If a Board awards only
letter grades without providing an equivalent percentage of marks on
the grade sheet, the candidate should obtain a certificate from the
Board specifying the equivalent marks as percentages (total aggregate
in Class X and PCM for Class 10 +2), and submit it at the time of
counseling. Candidates should produce equivalence certificate if
required at the time of counseling.
 Points to be noted
 The year of passing the Qualifying Examination is the year in which
the candidate has passed, for the first time, any of the examinations
listed in IV.3. above.
 The offer of admission is subject to verification of original
certificates/ documents at the time of Counselling. If any candidate is
found ineligible at a later date, even after admission to the
Institute, his/ her admission will be cancelled.
