Context:
The West Asia conflict has increased incidents of GPS jamming and spoofing near the Strait of Hormuz, affecting maritime navigation and security.
Key Highlights:
- Types of Electronic Interference
- GPS Jamming:
- Emits strong signals to block GNSS signals.
- Causes loss of navigation data.
- GPS Spoofing:
- Sends fake signals mimicking real satellites.
- Leads to incorrect positioning or route deviation.
- Broader Concept
- Part of electronic warfare using electromagnetic interference.
- Impact Areas
- Affects:
- Commercial shipping
- Aviation
- Military operations
- Can lead to:
- Navigation errors
- Collision risks
- Strategic vulnerabilities
- Global Navigation Systems
- GNSS (Global Navigation Satellite System):
- GPS (USA)
- GLONASS (Russia)
- Galileo (EU)
- NavIC (India)
Relevant Prelims Points:
- GNSS: Satellite systems providing Positioning, Navigation, Timing (PNT).
- GPS Jamming vs Spoofing: Blocking vs misleading signals.
- NavIC: India’s regional navigation system.
Relevant Mains Points:
- Increasing role of electronic warfare in modern conflicts.
- Threat to global trade routes and maritime security.
- Need for resilient navigation systems and backups.
- Importance for India’s strategic and defense preparedness.
- Way Forward
- Develop anti-jamming and anti-spoofing technologies.
- Strengthen indigenous systems like NavIC.
- Enhance international maritime cooperation.
