[amsat-bb] Re: Azimuth question

[Art McBride]

Randy,
True North is used as a reference. Magnetic North changes with observer
location and time. A user of Magnetic North is expected to make the
correction to True North. Some satellite prediction programs give position
of Sun and Moon to calibrate your antennas by knowing your Position and Time

Subject: [amsat-bb] Azimuth question

Is azimuth base on true or magnetic north
When lining up the antenna system for satellites?
When I looked it up, says true north.
Is that true for ALL satrellite tracking software?

One website says 12 degrees 58 seconds West is the magnetic declination.
So does that mean turn my antenna west by that amount from
Magnetic north?
