YES - AMSAT-UK knows the value of publicity, marketing, and planning. Their
use of several
social media programs is fantastic. They KNOW how to throw a "party."

<http://www.amsat.org/amsat/articles/g3ruh/111.html>Orbit Plane:* Fixed
(almost) with respect to the stars, in orientation defined by argument of
perigee, inclination and RAAN.
Origin: Earth's centre.

motion

I think I understand most of the math in the algorithm. In the above

HI,
Right Ascention of the Ascending node.
The point in the orbit at which it crosses the equator going northbound.
Here 's a good example:

Hi Norm,
RAAN = right ascension of the ascending node

Right Angle (of the) Ascending Node? I think I got it. Much to play with
here.

Yes, but one thing I've never quite understood was how to convert RAAN
into Longitude. All the neat explanations on non-earthly frames of
reference and vernal equinoxes stop short of explaining how to start
with RAAN (in a set of elements) and compute forward in time from the
epoch to get the longitude of the ascending node of the current orbit.
Anyone with a link to an online resource that can help make this clear?

Is the Auburn Sat operational?
Are the KEPS in the Celtex? What is it's number.
Just worked W1AW/2 FM 30 on SO 50 Pass.
The new K4AMG circular M2 antennas and AR2 SW Preamps are working great.
Will be on other birds this weekend as time permits.
