What is Smart India Hackathon (SIH) 2026?

Smart India Hackathon (SIH) is the world’s biggest open innovation hackathon organized by the Ministry of Education, AICTE, and MIC, where student teams build hardware and software solutions for problem statements submitted by Government Ministries, Departments, and State Agencies.

How many problem statements are released in SIH 2026?

SIH 2026 features 226 official problem statements, comprising 172 Software category statements and 54 Hardware category statements across themes like Smart Automation, Agriculture, Disaster Management, MedTech, Clean Water, and Cybersecurity.

How does the SIH ONE AI Team Matchmaker work?

The SIH ONE Matchmaker takes your 6-member team’s frontend/backend/AI skills, hardware experience, domain preferences, and exclusions, then runs a multi-factor weighted scoring algorithm to rank the top 25 highest-fit problem statements.

How does the B-dot detumbling algorithm stabilize the satellite after deployment from the launch vehicle rocket?

Upon ejection from the rocket deployer (P-POD), the CubeSat experiences rapid tip-off rotational spin; the B-dot algorithm measures the time rate-of-change of the Earth's magnetic field vector (dB/dt) using magnetometers and energizes the 3-axis magnetorquer coils in opposition, generating magnetic torque that detumbles the satellite to zero spin within 2 orbits.

How does the hardware survive Single Event Upsets (SEU) and radiation latch-ups in space orbit?

The PCB incorporates active high-speed current-limiting switches on all power rails: if a cosmic heavy ion causes a destructive latch-up short circuit, the power controller detects the over-current in 10 microseconds and power-cycles the affected subsystem, while critical memory utilizes Triple Modular Redundancy (TMR).

How does the burn-wire deployment mechanism release the antennas reliably in space vacuum?

Deployable antennas and solar arrays are held under spring tension by high-tensile Dyneema/nylon monofilament lines wound around surface-mount nichrome heating resistors; when commanded, a 1-amp current pulses through the resistor for 3 seconds, cleanly melting the line and deploying the antennas with zero mechanical pyrotechnics.

30-Second Plain English Summary

AICTE Open Innovation: Space Technology (Hardware) — Engineering colleges and aerospace startups in India developing CubeSat satellite missions face astronomical launch costs and failure rates due to lack of space-qualified, radiation-tolerant hardware subsystems (Onboard Computer - OBC, Electrical Power System - EPS, Attitude Determination and Control - ADCS). Build a 1U Space-Qualified Educational CubeSat Engineering Model and Ground Testing Rig featuring a dual-redundant ARM Cortex-M7 Onboard Computer, deployable MPPT solar panels, 3-axis magnetorquer ADCS attitude stabilization, and UHF/VHF amateur radio telemetry transceivers.
