Longitude of [OMEGA] Angle drawn in the ecliptic plane ascending node
between the vernal equinox direction and the line where the orbit intersects the ecliptic with the object moving south to north.
In simulations, the GEO satellite starts at the ascending node
, and the radar is left looking during the orbital period.
In Figure 2 we can see that the mean longitude of the ascending node
, [OMEGA], changes slowly its value from about 77[degrees] 5000 yr ago to 349[degrees] 1000 yr in the future, that is, changing its value with velocity of about -52.8"/yr.
where a, e, i, [OMEGA], [omega], and f are the usual Keplerian orbital elements, semimajor axis, eccentricity, inclination, longitude of the ascending node
, and true anomaly, respectively, p is the semilatus rectum, [mu] the gravitational parameter, and n is the orbital mean motion.
It will take 105.5 years between the June 2012 transit of Venus and the December 2117 transit (which occurs at Venus's ascending node
A list of transits from -2999 to 3000 was given by Meeus, (10) who introduced the alphabetical system for identifying each series, which uses upper case characters for transits occurring at the ascending node
and the lower case for those at the descending node.

The right ascension of the ascending node
[OMEGA], the inclination of the orbital plane I, and the arguments of declination [u.sub.1] and [u.sub.2] from the equations
Initial orbit design consists of six standard orbital elements: semimajor axis a, eccentricity e, inclination i, longitude of ascending node
[OMEGA], argument of perigee w, and mean anomaly M.
