Geolocation is an easy concept to understand. That said, the formulas behind it can become a bit complicated, calculation errors associated with it can be difficult to minimize, and some signals are just not as easy to work with. The concept seems to ultimately work with any portion of the spectrum, giving it technical longevity with respect to security.
- [Instructor] Geolocation can be a bit overwhelming. There is definitely an art form to it as well, due to some really fun physics effects. Don't worry, though, it isn't that bad. Geolocation is the identification of the real-world geographic location of an object, such as a radar source, mobile phone, or Internet-connected computer terminal. I think the definition doesn't mention the accuracy of the location.
It could mean a direction, country, state, city, neighborhood, house, room, or even an inch. It is important to understand that sometimes geolocation is wrong and we will go over why in a bit. So geolocation most often uses radio frequencies. This is just sort of where it started, though. You can technically use other pieces of data, such as an IP address, MAC address, the device's GPS, to supplement the concept.
Early uses focused on lines-of-bearing, or LOBs. These were called direction finding which essentially tells you which direction the emitter was in. Modern uses include geocaching in the new Pokemon Go game. Other uses are navigation, shipping tracking, wildlife tracking or locating emergency beacons in the remote wilderness. Radiolocation is defined as the process of finding the location of something through the use of radio waves.
So to geolocate something, you can use radio location techniques. Radio waves are only a small portion of the electromagnetic spectrum so keep in mind this concept can be applied to others. Some parts of the spectrum are really easy to locate, though, which actually makes a decent representation in a lot of these examples to come.
