// ORBITAL LOGISTICS AND PROPULSION TERM
Anomaly
In orbital mechanics, this term refers to an angle used to describe a satellite's position in its orbit. There are different types, like true, eccentric, and mean anomaly.
TECHNICAL DEFINITION
In astrodynamics, an anomaly is an angular parameter (e.g., true, eccentric, mean) that defines the position of an orbiting body along its elliptical path relative to the primary body and the periapsis.
BACKGROUND
Northrop Grumman Corporation, headquartered in West Falls Church, Virginia, is an American aerospace and defense company that designs and manufactures systems for aeronautics, defense, missions, and space. The company is the 5th largest contractor of the U.S. federal government; it receives over 2% of total spending by the federal government of the United States on contractors.
