IIT Madras designs drones – There is a delightful news with regards to Indian Institute of Technology Madras ( IIT Madras ). Researchers at the prestigious educational institution developed an Artificial-Intelligence empowered drones that can counter rogue drones.
These drones are meant for armed forces and law enforcement agencies. The special point with regards to these drones is that they can detect rogue drones visually using Algorithms powered by Artificial Intelligence and hack them to change their flight path or land safely. These can be of very good assistance to armed forces and law enforcing agencies.

Using the Internet to control the drones also allows for deploying a swarm of drones that can intelligently detect and track people, drones, vehicles and other objects.
The team who designed the system comprised Vasu Gupta, a final year B. Tech student, Department of Aerospace Engineering, IIT Madras and Rishabh Vashistha, a Project Associate working in RAFT Lab, Department of Aerospace Engineering, IIT Madras. Dr. Ranjith Mohan, Assistant Professor, Department of Aerospace Engineering, IIT Madras was the mentor for the team.

Ranjith Mohan said their current prototype is equipped to detect and track objects visually, precisely land and fly over internet. Their next step will be to conduct exhaustive tests on the system and ensure its reliability for catering to a wide range of demanding missions that pose challenge to our law enforcement and defence agencies.
The programmable nature of our aerial vehicles also opens up the possibility of swarming multiple vehicles to act as a team and accomplish a common mission, he said.
Following this, the drone generates fake GPS packets by mathematically modelling the time differences at the receiver’s end. Using four of such time differences, the GPS sensor calculates its 3D position and calibrates the rogue drones’ time to our spoofed clock. This way, we alter the latitude, longitude, altitude and time of the rogue drones, he said.
Rishabh Vashistha said algorithmically altering the 3D position allows us to move the target drone locally. Moreover, when a large variance is given in the spoofed GPS position, a fail safe (if any) is invoked at the target side which results in a safe landing of the target drone.
He further said they have tested this electronic countermeasure of ours against nearly all the civilian GPS receivers used by the UAV industry such as ublox, DJI inhouse GNSS and we have been able to take down the drones almost instantaneously within 4-5 seconds, he said.

Millions of Class 10 students across India are refreshing their screens right now, waiting for one crucial announcement — the CBSE Class 10 Second Board Result 2026.
This year marks a historic shift in Indian education. For the first time ever, CBSE conducted board exams twice in a single academic session, in line with the National Education Policy (NEP) 2020. If you appeared for the Phase 2 (Second Board) exams held between May 15 and May 21, 2026, this guide is your complete roadmap.
You will learn exactly when the result is expected, where to check it, what the symbols on your marksheet mean, and what steps to take — whether you’ve passed, need improvement, or are planning to opt for re-evaluation.
Let’s get straight to it.
What Is the CBSE Class 10 Second Board Exam?
The CBSE Class 10 Second Board Exam (also called Phase 2 or the Improvement Exam) is a second attempt at the board examination introduced for the 2025–26 academic session. It is designed to give students a fair second chance — a concept at the heart of NEP 2020.
Why Was It Introduced?
Reduce exam pressure: Students no longer risk their entire future on a single exam day.
Best score retention: CBSE retains the higher of the two scores in up to three improvement subjects.
Flexibility: Phase 2 is completely optional for students who are satisfied with their Phase 1 scores.

Eligibility
Not everyone was eligible for the Phase 2 exams. Here are the criteria CBSE set:
Appeared in Phase 1: Only students who sat for Phase 1 exams (February–March 2026) were eligible.
Minimum 75% attendance in school was mandatory.
Internal assessment completion was required.
School-submitted LOC (List of Candidates): Regular students could not register independently — schools submitted the applications on their behalf.
Students who studied all subjects (including additional subjects) for two full academic years were considered eligible.
Students placing in the compartment category from the 2025 examination cycle were also eligible for the May 2026 second board exam.
Important Registration Details
Registration for Phase 2 opened and closed quickly. Here’s what happened:
The LOC (List of Candidates) submission window opened on April 16, 2026, and closed on April 20, 2026 (no late fee).
A late fee window was available from April 21 to April 22, 2026.
After April 22, no new applications were accepted under any circumstances.
Schools managed the entire registration process — students needed to coordinate with their school well in advance.
If you missed the registration window, the next opportunity would be the Compartment Exam in July 2026, provided your result warrants it.
Subject-Wise Registration Data
The response to Phase 2 was massive. A total of 6,68,854 students registered, broken down as follows:
Improvement category: 5,25,655 students
Compartment category: 85,285 students
Both improvement and compartment: 57,914 students
