सारांश
Flights in the Delhi-NCR region have been experiencing disruptions due to GPS spoofing incidents, where false GPS signals mislead aircraft navigation systems. The Ministry of Civil Aviation and the Directorate General of Civil Aviation (DGCA) are actively investigating the source of these malicious signals.
This issue poses a significant threat to aviation safety, as accurate navigation is crucial for flight operations. Essentially, someone is intentionally sending fake GPS signals, which could potentially cause serious navigation errors for aircraft, and authorities are scrambling to identify and neutralize this threat.
पृष्ठभूमि
Global Positioning System (GPS) is a satellite-based navigation system owned by the United States government and operated by the United States Space Force. It is one of several Global Navigation Satellite Systems (GNSS) that provide location and time information. GPS signals are crucial for various applications, including aviation, maritime navigation, land transport, and military operations.
The vulnerability of GPS signals to interference, both intentional and unintentional, has been a known concern. Intentional interference can take the form of jamming (blocking signals) or spoofing (transmitting false signals).
नवीनतम घटनाक्रम
Recent incidents in the Delhi-NCR region involving GPS spoofing have caused disruptions to flights. This involves malicious actors transmitting false GPS signals that mislead aircraft navigation systems, posing a significant threat to aviation safety.
The Ministry of Civil Aviation (MoCA) and the Directorate General of Civil Aviation (DGCA) are actively investigating the source of these signals to identify and neutralize the threat. This highlights a growing concern about the security and resilience of critical navigation infrastructure against sophisticated cyber threats.
बहुविकल्पीय प्रश्न (MCQ)
1. With reference to the recent GPS spoofing incidents affecting flights in India, consider the following statements: 1. GPS spoofing involves transmitting false GPS signals to mislead navigation systems. 2. Such incidents primarily affect only civilian aircraft, as military aircraft use a different navigation system. 3. The Ministry of Civil Aviation and the Directorate General of Civil Aviation (DGCA) are the primary agencies investigating these incidents. Which of the statements given above is/are correct?
- A.1 only
- B.1 and 3 only
- C.2 and 3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: B
Statement 1 is correct. GPS spoofing is indeed the act of transmitting false GPS signals to deceive a receiver. Statement 2 is incorrect. While military aircraft often use encrypted, more robust GPS signals (like the M-code for US military GPS), they are not entirely immune to sophisticated spoofing attacks, and civilian GPS signals are also used. More importantly, the impact on civilian aviation is a major concern. Statement 3 is correct. As per the news, MoCA and DGCA are actively investigating the source of these malicious signals.
2. Consider the following statements regarding Global Navigation Satellite Systems (GNSS): 1. NavIC (Navigation with Indian Constellation) provides positioning services only to India and its surrounding regions. 2. Galileo is a GNSS developed by the European Union and is entirely independent of the US-owned GPS. 3. GLONASS, developed by Russia, operates on a different coordinate system than GPS. Which of the statements given above is/are correct?
- A.1 and 2 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: D
Statement 1 is correct. NavIC is a regional navigation satellite system designed to provide accurate real-time positioning and timing services over India and a region extending up to 1,500 km around the Indian mainland. Statement 2 is correct. Galileo is the European Union's global navigation satellite system, providing independent, highly accurate positioning and timing information. Statement 3 is correct. GLONASS (Globalnaya Navigatsionnaya Sputnikovaya Sistema) uses a different coordinate system (PZ-90.11) and time reference compared to GPS (WGS 84).
3. In the context of satellite navigation and aviation safety, which of the following statements correctly differentiates between GPS 'jamming' and 'spoofing'? 1. Jamming aims to block or overwhelm legitimate GPS signals, while spoofing aims to deceive a receiver with false signals. 2. Jamming typically causes a receiver to lose its position fix, whereas spoofing causes a receiver to report an incorrect, but seemingly valid, position. 3. Anti-jamming techniques are generally more complex and expensive to implement than anti-spoofing measures. Select the correct answer using the code given below:
- A.1 only
- B.1 and 2 only
- C.2 and 3 only
- D.1, 2 and 3
उत्तर देखें
सही उत्तर: B
Statement 1 is correct. Jamming involves transmitting noise or interference to prevent a GPS receiver from acquiring or tracking legitimate signals. Spoofing involves transmitting fake GPS signals that mimic legitimate ones to trick the receiver into calculating an incorrect position. Statement 2 is correct. Jamming often results in a 'loss of signal' or 'no fix' error, while spoofing leads to the receiver believing it is at a location other than its true position, without necessarily indicating an error. Statement 3 is incorrect. Anti-spoofing measures, which often involve complex signal authentication, cryptographic techniques, and multi-sensor integration, are generally considered more complex and expensive to implement effectively than basic anti-jamming techniques (though advanced anti-jamming can also be complex).
