U may wonder wat does 26/11 mean here, as my blog title suggests that this is a tech blog. Well right, this is a tech blog, and i dedicate this post to my fellow countrymen who lost their lives in this Mumbai attack. I salute the NSG's and Policemen who fought against the bad guys bravely, for 3 continuous days.
This post is about how technology helped the bad guys. It is said that the bad guys made use of GPS and Google Earth. GPS is the acronym Global Positioning System. GPS helps you to reach a place anywhere in this world. If suppose a group of people get lost, while travelling towards Mumbai in a boat, they can use GPS to find the right direction. GPS can also be used to locate your current positio
Well you must be thinking now, how GPS works. A GPS reciever recieves the signals from satellite and gives the information to the user. A GPS reciever recieves information from more than 4 satellites. The reciever decides from which satellite it has to recieve the signals. It selects the satellite which provides the strongest signals at that location from the 30 satellites available exclusively availabale for GPS. The reciever gets the signals from the orbit of the satellites and gives information about the locations to the user using a method called geometric trilateration. The GPS can show you routes to travel, if you set your destination.
The next one is Google Earth. This is a common software which everyone would have used. This software gives the images which are captured in the satellite. These images are placed on a virtual sphere. Earlier they used to show only important landmarks but nowadays they provide all the details like the shops present in a street and sensitive details like military installations. They provide 360 degree view of streets in USA and Japan from the ground level. Using google earth and GPS, travelling to any unknown place is not a hectic task today.
People have started blaming that advancement of technology is the reason for this attack. Well the answer is partly right. The fact is the bad guys have learnt to use the technology. We people are still beginners in tech. The same GPS and Google Earth can be used to trace the bad guys activities and capture them. So we are not supposed to blame the tech for this attack. If technology is used constructively,no terrorists can exist in this earth!
