This technology is in widespread use today, and the growth will most likely be based on the number of rich countries engaged in âwarsâ at any given time. Instead, Consumer and Commercial Drones are where the real growth is expected to be at. You may have decided you wanted to invest in drones because one was buzzing around your neighborhood recently, or you noticed theyâve started cropping up an awful lot in reality TV, NatGeo shows, and YouTube videos.
Degrees and Minutes The distance between degrees of longitude is about 60 nautical miles at the equator. It is less further north or south as the longitude lines converge towards the poles. Degrees of latitude are always 60 nautical miles apart.At the equator, a grid of 1Â° of longitude by 1Â° of latitude covers about 3,600 square miles.For greater precision, degrees are divided into 60 minutes (') - of distance, not time.y comparison, a statute mile is 5,280 feet or about 87% of a nautical mile and a kilometre is 54%. One minute of latitude equals one nautical mile and degrees of latitude are 60 nm apart. The distance between degrees of longitude isn't constant because they converge towards the poles.
Longitude at a point may be determined by calculating the time difference between that at its location and Coordinated Universal Time (UTC). Since there are 24 hours in a day and 360 degrees in a circle, the sun moves across the sky at a rate of 15 degrees per hour (360Â° Ã· 24 hours = 15Â° per hour). So if the time zone a person is in is three hours ahead of UTC then that person is near 45Â° longitude (3 hours Ã 15Â° per hour = 45Â°).
