orbits

For my uncle Zbys who watched the planets and stars.


Types and functions for dealing with Kepler orbits.

The main data type is Orbit, which describes the path of a body in orbit.

Nomenclature

Symbol Meaning Notes
a Semi-major axis Negative for hyperbolic orbits
b Semi-minor axis Negative for hyperbolic orbits
e Eccentricity
q Periapsis
i Inclination
μ Standard gravitational parameter
Ω Longitude of the ascending node
l Semi-latus Rectum
n Mean motion
p Period
t Time since periapse
M Mean anomaly
E Eccentric anomaly Only for elliptic orbits
H Hyperbolic anomaly Only for hyperbolic orbits
ν True anomaly
h Specific angular momentum
ε Specific orbital energy
εp Specific potential energy
εk Specific kinetic energy
v Orbital speed or velocity
r The radius to the orbiting body
φ Flight path angle

Note that in the Haskell source uppercase symbols such as Ω and M are written with a leading underscore.

Implementation

This package makes use of the units package to ensure that the implementation is correct regarding units of measure.
