9. Miscellaneous S&T

Drones

Cue Words	Notes
What are drones and what are they used for?	Unmanned aircraft (UA) operating autonomously or remotely. Initially for defense, now used in agriculture, mapping, law enforcement. Offer better safety and efficiency than traditional aircraft.
What are the key applications of drones?	Survey & Mapping: Quick mapping for construction, land records. Ex: SVAMITVA scheme. Agriculture: Crop health, pest detection, pesticide spraying. Ex: Kisan drones for spraying nutrients. Search & Rescue: Thermal imaging + GPS for disaster zones. Ex: MQ-9B drones from US. Environmental Monitoring: Wildlife tracking, pollution, deforestation. Delivery & Logistics: Fast delivery in remote areas. Disaster Response: Assess damage, hazards, situational awareness. Security & Surveillance: Monitor borders, public areas, critical assets.
What is India's drone policy and way forward?	Categorization: Nano, Micro, Small, Medium, Large. Registration: All except Nano via Digital Sky portal. Permit: Required for Micro and above from DGCA. Training: Certified programs for drone pilots. Security vs. Benefits: Balanced guidelines for safety and innovation. Anti-Drone Systems: DRDO working on jamming, lasers, missiles. Investment: Indigenous UAVs and counter-drone tech for critical zones.

India's Ballistic Missile Defence (BMD) Programme

Cue Words	Notes
What is the aim of India's BMD Programme?	Two-tier system to intercept ballistic missiles exo-atmospheric & endo-atmospheric.
What are Phase-I and Phase-II of BMD?	Phase-I: Covers missiles up to 2,000 km. Components: PAD (exo), AAD (endo), Swordfish Radar. Status: Tested, deployed. Phase-II: Targets 5,000 km range missiles. AD-1: Dual-stage interceptor (endo & low-exo). Status: Tested. AD-2: For IRBMs (3,000–5,500 km). Status: Under development.
What is the strategic significance and what are the challenges?	Strategic Significance: Enhances security, supports No First Use policy, boosts indigenous tech & second-strike capability. Challenges: Arms Race Risk, High Costs, Integration complexity with defense systems.

Missiles — FATEH, Cruise vs Ballistic, S-400

Cue Words	Notes
What is the FATEH Missile?	FATEH Missile (Iran): In news for precision-guided short-range ballistic capability.
What is the difference between Cruise and Ballistic Missiles?	Cruise: Low-altitude, guided throughout flight, slower. Ballistic: High-arc trajectory, mostly unguided post-launch, faster.
What is the S-400 Missile System?	Russian air defense system; intercepts aircraft & missiles up to 400 km range. India purchased from Russia.

Advanced Driver Assistance System (ADAS)

Cue Words	Notes
What is ADAS and what are its features?	Definition: Digital in-vehicle system using sensors & AI for driver safety. Features: Auto-brake, collision warning, lane assist, adaptive cruise control.
What are the challenges and future directions for ADAS?	Challenges: Liability issues, poor roads, mixed traffic, cyber risks, low awareness. Future Directions: Centralized controllers, AI, better data processing, higher automation, cost reduction. Goal: Safer roads, efficient traffic, gradual move to autonomous vehicles.

Satellite-based (GPS) Toll Collection System

Cue Words	Notes
What is the context of GPS-based toll collection?	NHAI to implement GPS-based tolling to reduce congestion at toll booths.
What are the benefits of GPS-based toll collection?	Usage-Based Charging: Pay for actual distance traveled, ensuring fairness. No Toll Plaza Stops: Enables seamless, faster travel. Efficiency Incentives: Lower tolls for fuel-efficient vehicles. Road Preservation: Higher fees for heavy vehicles to reduce wear. Improved System: More equitable and efficient than FASTag.
How does FASTag differ from GPS-based toll collection?	Technology: FASTag uses RFID; GPS-based uses GPS. Deduction: FASTag — automatic deduction at toll booths; GPS — deduction through tracking of GPS coordinates. Detection: FASTag — detected when vehicles approach a toll booth; GPS — entire travel route is tracked. Infrastructure: FASTag — toll booths need to be stationed; GPS — removal of all physical toll booths and plazas. Status: FASTag — mandatory since February 2021; GPS — planned to be implemented around 2022.

Vigyan Dhara Scheme
