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, 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 means electronics used in aerospace systems. The students opting for Avionics 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 Digital Signal Processing (DSP), RF & Microwave Communications, Antenna, Power Electronics, Microelectronics, Control system etc.

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 Earth System Sciences, Remote Sensing and GIS, Astronomy, Astrophysics and Chemical Systems.

People with B. Tech Degree in Physical Sciences 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 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). The maximum time limit allowed for successful completion of a programme is six years, but any extension beyond the normal four years renders the student ineligible for absorption in ISRO. 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. If a student is not eligible to join ISRO, penalty provisions in the bond will be attracted.

A student should earn at least 29 credits at the end of first year to continue his/her studies in IIST. Students who fail to earn at least 29 credits at the end of the first year will have to leave the academic programme and the Institute. Similarly students are required to earn at least 76 credits at the end of the second year and at least 124 credits at the end of the third year to continue their studies in IIST. The Institute makes every effort to support the weaker students by offering Winter/ Summer courses every year.
