arc Explanation: I have certainly come across "degrees/minutes of arc" many times in astronomy referring to the sky (and the distinction is not made there by the use of "celestial"); from what I can gather, it is not geneally made in the measurement of longitude on earth either by calling it "Earth's/terrestrial arc" etc. Given the context, I think it ought to be perfectly obvious that it is referring to the earth as opposed to the sky - though I wouldn't disagree with "the Earth's arc" or "terrestrial arc". Here are a couple of examples of the use of simply "arc" to refer to the Earth as opposed to the sky: "Both methods were tested by sea trials. The lunar tables permitted the determination of longitude within four minutes of arc, but with Harrison's chronometer the precision was only one minute of arc. Ultimately, portions of the prize money were awarded to Mayer’s widow, Euler, and Harrison..." http://www.aticourses.com/global_positioning_system.htm -------------------------------------------------- Note added at 7 hrs (2006-03-27 23:17:38 GMT) -------------------------------------------------- Sorry, that was only one! But there must be thousands of others out there. "The NMEA data is plainly "stuck", the latitude and longitude values do not change over a period of possibly 30 seconds. This differs from a range of other GPS devices Garmin/Pretec and Pino units where we typically see a change of 1/0000 minutes of arc, equivalent to 0.18 meters." http://discussion.forum.nokia.com/forum/archive/index.php/t-... |
