दिल्ली एयरपोर्ट के फ्लाइट्स की GPS से छेड़छाड़ हुई: पायलट को रनवे पर खेत दिखे थे, आसमान में विमानों के बीच दूरी बढ़ाकर हादसे टाले

Due to tampering in GPS, ATS (Air Traffic Control) also started receiving coordinates with delay. In such a situation, instead of landing at Delhi airport, the planes were diverted towards Jaipur and nearby airports.

Due to increase in air traffic, the distance between planes in the air space was increased. Due to which any major accident could be avoided.

On 7 November, flight operations were disrupted for more than 12 hours due to a technical glitch in ATC’s Automatic Message Switch System (AMSS) at IGI. More than 800 domestic and international flights were delayed, while 20 had to be cancelled. Airport operations returned to normal after 48 hours.

Apprehension: ‘Signal blast’ done with copy of open civilian message of GPS An eminent cyber security expert associated with the security establishment told ‘Bhaskar’ that copying the civilian GPS signals operated from America earlier seemed only theoretical but now it is being done very easily. There is a possibility that the hackers got help from some foreign government in the Delhi conspiracy, this is a big danger.

It is suspected that in the recent incident, hackers did a fake signal blast (sending a large number of signals). Confusing situations were created in front of the pilots, then the automatic message switching system also crashed.

US civilian GPS provides Open CA signals which are received based on pseudo random noise (PRN). PRN signals can be copied. Whereas military grade GPS are encrypted.

Danger: 465 cases of GPS tampering reported Cases of GPS tampering of civilian aircraft have increased in the country. DGCA recorded more than 465 such fake signals in recent months. Most of the incidents so far have been reported in border areas like Jammu and Amritsar.

America is now developing Chimera signal for civilian signals also. These signals of GPS-3 will be secure by being encrypted.

Solution: Indigenous ‘Navik’ navigation system ready ISRO’s indigenous satellite system ‘Navik’ will enhance aviation security. Its standards were decided in October. It is completely under the control of India. According to experts, the recent incident at Delhi airport could have been prevented if Navigator was in use.

High level investigation into sudden malfunction begins

Civil Aviation Minister Ram Mohan Naidu on Friday reviewed the functioning of the ATC messaging system at Delhi Airport after a technical glitch. He also went to ATC Tower.

A high-level investigation has started into the malfunction in the air traffic system of Delhi Airport. This decision was taken by the Central Government in a meeting held at the National Security Advisor (NSA) office on Friday evening itself. In this, all other stakeholders including airport, security agencies were called. The investigation will also see whether external forces or cyber attacks were involved in this.

Now know what happened on November 7?

Flight operations were affected for more than 12 hours on Friday due to a technical glitch in the Automatic Message Switch System (AMSS) of Air Traffic Control (ATC) at Delhi Airport. More than 800 domestic and international flights were delayed and 20 had to be cancelled. The fault in the system occurred at 9 am. It was around 9:30 pm. However, complaints were also received on Thursday evening.

Airports Authority of India (AAI) had said at 8:45 pm on Friday that the AMSS system is active and now working properly. Due to system glitch, passengers were troubled throughout the day at the airport. There were long queues near the boarding gate. According to flight tracking website Flightradar24, all flights were delayed by an average of 50 minutes.

The effect of flight delay at Delhi airport was also visible at many airports across the country including Mumbai, Bhopal, Chandigarh, Amritsar. Flights going to and from Delhi were also delayed. Indigo, Air India, Air India Express, SpiceJet and Akasa Airlines had given information about flights throughout the day.

Know what is Automatic Message Switching System

AMSS (Automatic Message Switching System) is a computer network system associated with the Air Traffic Control Service. Thousands of text-based messages are sent in real-time to pilots, ground staff and other airports every day through AMSS.

What happens in these messages-

• Complete information about each flight’s route, altitude, fuel etc.
• when did the flight take off
• when did the flight land
• flight delay notice
• Plan changed or canceled
• weather updates
• warnings in airspace

How does this work?

Airlines or pilots draw up flight plans. AMSS checks that data and sends it to the right place (ATC, other airports, concerned airline). If the route or weather changes, the system immediately sends updates to everyone. This keeps the entire air traffic route in sync.

What happens if AMSS doesn’t work?

If the system fails, like it happened in Delhi –

• Automatic messages off: Flight-plan, route clearance and updates have to be done manually.
• Workload on ATC: Every message or approval has to be sent by humans themselves.
• Delays and Congestion: When it takes time to approve a flight-plan, takeoff-landing becomes slow. This increases the crowd at the airport.
• Security Risk: In the absence of automatic coordination, the possibility of human error increases.

ATC is the traffic police of airplanes, understand from AI images

Air Traffic Control (ATC) is the central controlling system present at airports. It issues instructions to aircraft on the ground, in the air and in different parts of the sky. In simple language, it is like the traffic police, but only for aeroplanes.

World’s largest airport system failure

• CrowdStrike Global IT Outage from 19 to 23 July 2024. 7,000 flights were cancelled. 1.3 million passengers worldwide were affected.
• UK ATC failure of 28–29 August 2023. More than 600 flights were grounded at 6 major airports in the UK. 7 lakh passengers affected.
• On August 8, 2016, America’s Delta data center failed, more than 2100 flights were affected. 90 thousand passengers were affected.
