IIRS ISRO Internship 2026: Eligibility, Deadlines & How to Apply

Dreaming of working inside an ISRO lab, even for a few weeks? The IIRS ISRO Internship quietly offers that chance to students across India.

Run by the Indian Institute of Remote Sensing (IIRS) in Dehradun, this program allows UG, PG, and PhD students to work on real projects related to geospatial technology, remote sensing, and earth sciences. No flashy marketing, no massive announcements. But the experience can be incredibly valuable.

And yes, students from many science and engineering backgrounds can apply.

IIRS ISRO Internship 2026 Eligibility

Let's get the basics clear first. The IIRS ISRO Internship is open to students studying science or technology disciplines from recognised universities in India or abroad.

But there are a few academic requirements you can't ignore.

• Applicant must be an Indian citizen
• Must be pursuing UG, PG, or PhD in Science or Technology fields
• Minimum 60% aggregate marks or CGPA 6.32 on a 10-point scale
• Students who completed their degree within the last six months can also apply

Selection isn't automatic. Seats depend heavily on whether an IIRS faculty member is available and willing to supervise the proposed project.

In simple words, good academics help, but the relevance of your subject and project idea matters just as much.

IIRS ISRO Student Project Trainee Scheme (Detailed Criteria)

Apart from the standard internship route, IIRS also runs a Student Project Trainee Scheme. This is typically used for academic project work.

The eligibility varies slightly depending on the degree you're pursuing.

Degree Eligibility Minimum Duration
| BE / BTech  | Must have completed 6th semester  | 45 days
| ME / MTech  | Must have completed 1st semester  | 120 days
| BSc / Diploma  | Final year students only  | 45 days
| MSc  | Must have completed 1st semester  | 120 days
| PhD  | Coursework must be completed  | 30 months

All these categories still require the same academic benchmark of 60% marks or equivalent CGPA.

Also, the internship duration cannot be extended once approved. I've seen students assume extensions are easy to get. At ISRO centres, that almost never happens.

IIRS ISRO Internship Duration and Work Areas

The minimum duration of the IIRS ISRO Internship is 45 days. Depending on your course and project, it can extend up to one year.

The work generally aligns with IIRS research domains such as:

• Remote sensing
• Geoinformatics
• Photogrammetry
• Disaster management sciences
• Agriculture and soil studies
• Water resources and hydrology
• Urban and regional studies
• Atmospheric and marine sciences

One small restriction though. Interns are allowed only in unclassified areas of ISRO labs. Sensitive research zones remain restricted.

Stipend and Facilities at IIRS Internship

Here's the honest part. The IIRS ISRO Internship does not provide any stipend.

No financial assistance. And accommodation is not provided either.

So you'll need to arrange housing and travel expenses on your own if selected. That said, many students still apply because the exposure to ISRO research environments is hard to replicate elsewhere.

At the end of the program, successful interns receive an official internship certificate after submitting their project report and completing evaluation.

IIRS ISRO Internship 2026 Application Deadlines

Applications are accepted twice every year.

• 31 March
• 31 October

Missing these deadlines means waiting for the next cycle. And yes, it happens more often than you'd think.

Pro Tips to Increase Your Chances

Now, a quick editorial note from experience.

Students who simply apply with generic interests rarely get selected. But those who clearly connect their coursework to remote sensing or geospatial applications often stand out.

A short, focused project proposal helps. And a strong recommendation from your professor makes a noticeable difference.

Honestly, ISRO centres prefer students who already show curiosity about earth observation, GIS tools, or satellite data analysis.
