Argument of latitude

Angular parameter in celestial mechanics

In celestial mechanics, the argument of latitude ( u {\displaystyle u} ) is an angular parameter that defines the position of a body moving along a Kepler orbit. It is the angle between the ascending node and the body.

It is the sum of the more commonly used true anomaly and argument of periapsis.

u = ν + ω {\displaystyle u=\nu +\omega }

where  u {\displaystyle u} is the argument of latitude,  ν {\displaystyle \nu } the true anomaly, and  ω {\displaystyle \omega } the argument of periapsis.
