0 the direction towards the top of the earth along an imaginary line at an angle of 90° to the equator: --
The strings were arranged 8 degrees 40 minutes apart, covering an arc from 19.5 to 110.5 degrees clockwise from true north.
These directions are called "true north" and "true south", respectively.
West of the line of zero declination, a compass will give a reading that is east of true north.
By setting the date and latitude, the true north and the magnetic variation could be read from the instrument without the need for calculation.
The compass does not always point to true north.
The direction of astronomical true north is marked in the skies by the north celestial pole.
In the blog post, he defined a growth hacker as a person whose true north is growth.
The phase difference corresponds to the actual bearing relative to magnetic north (in some cases true north) that the receiver is from the station.
