The Indian Space Research Organisation (ISRO) is one of India's most admired scientific institutions, and its External Student Internship — hosted by the Indian Institute of Remote Sensing (IIRS) in Dehradun — lets students carry out genuine project work alongside space-applications scientists. IIRS is India's premier institute for remote sensing, geoinformatics and space-applications training, so a place here puts you close to the technology and the people who study and map India from space.
IIRS, an arm of ISRO, has trained generations of researchers and professionals in how satellite data is captured, processed and turned into decisions on the ground. Its External Student Internship is offered as a project traineeship: rather than observing from the sidelines, you are attached to ongoing work and expected to contribute. The subject areas span remote sensing, geoinformatics and GIS, satellite data analysis and allied fields, all under the guidance of IIRS and ISRO scientists.
Because it is a project-based traineeship rather than a classroom course, the experience is shaped heavily by the problem you are assigned and the mentor you work with. The specific projects on offer change over time, so treat the official portal as the source of truth for current themes and any lab-specific requirements.
Remote sensing and geoinformatics sit at the meeting point of earth science, data analysis and software. In a project like this, interns typically spend their time acquiring and cleaning satellite or geospatial datasets, running analysis, and presenting results as maps, figures or short reports.
Interns in a programme like this usually leave with a concrete deliverable — a mini-project, dataset or report — that they can talk about in future applications and interviews. For the exact scope of your own project, check the official portal and confirm with your assigned mentor.
The internship is open to Indian citizens studying at recognised Indian or international institutions, across levels:
A genuine interest in remote sensing, GIS or space applications matters as much as the marks on paper, and some background in these areas — through coursework, a project or self-study — will help you make the most of the time. If you are unsure whether your degree or institution qualifies, or how borderline marks are treated, confirm the details on the official portal before you apply.
Since you will need to be in Dehradun, factor travel, accommodation and living costs into your planning. Whether the institute offers any hostel or guest-house facility is not something to assume — check the official portal for current arrangements.
Applications are made online through the official IIRS admissions portal. As part of the process you will need to upload:
Applications are accepted twice a year. Registrations open from 1 July to 30 October (this window is currently open), and there is a separate window with a 31 March cut-off.
Some general good practice helps your chances:
Jobsii curates opportunities and links to the official page; applications are handled entirely on the institution's official portal. Details such as dates, eligibility and project themes can change, so always review the official page before applying. This is an unpaid internship — and, as with any genuine opportunity, you should never pay to apply.
Review the role details, deadline, and work mode before applying. Jobsii tracks the apply action so candidates can keep application history inside their dashboard.
