Galactic Navigation
Measuring Longitude
Now let's figure out how longitude works in galactic coordinates. Think of the
Earth again. How do you measure longitude on the Earth?
Lines of longitude on the Earth are oriented north and south. They all pass
through the North and South Poles. 0o longitude runs through
Greenwich, England. 0o is the Prime Meridian. If you travel eastward
from England 60o of longitude, you arive at Orsk, Russia. Orsk is at
60o east. If you travel westward 60o from England, you
arrive in Goose Bay, Newfoundland (Canada). Goose Bay is at 60o
west.
In galactic coordinates, the Prime Meridian, or 0o is at the galactic
center.
