Module nyx_space::cosmic

Provides the solar system planets, and state and ephemerides management.

Re-exports

• pub use crate::cosmic::GuidanceMode;
• pub use crate::cosmic::Orbit;
• pub use crate::cosmic::Spacecraft;

Modules

• eclipse
  The eclipse module allows finding eclipses and (conversely) visibility between a state and another one (e.g. a planet or the Sun).
• orientations
  Known orientation IDs defined for ease of access. All Cosm objects may be accessed via Cosm directly.

Structs

• BPlane
  Stores a B-Plane
• BPlaneTarget
• Cosm
• DragConfig
  The drag configuration for a spacecraft
• Euler3Axis
  A fixed three-axis Euler rotation
• Euler3AxisDt
  A time varying three-axis Euler rotation
• FrameTree
• IoError
  The error type for I/O operations of the Read, Write, Seek, and associated traits.
• NoRotation
• Orbit
  Orbit defines an orbital state
• OrbitDual
  Orbit defines an orbital state
• OrbitPartial
  A type which stores the partial of an element
• Spacecraft
  A spacecraft state, composed of its orbit, its dry and fuel (wet) masses (in kg), its SRP configuration, its drag configuration, its thruster configuration, and its guidance mode.
• SrpConfig
  The Solar Radiation Pressure configuration for a spacecraft
• Xb

Enums

• AngleUnit
• Bodies
  Defines the default celestial bodies in the provided de438 XB.
• EulerRotation
  Defines an Euler rotation, angle must be in radians
• Frame
• GuidanceMode
• IoErrorKind
  A list specifying general categories of I/O error.
• LightTimeCalc
  Enable or not light time correction for the computation of the celestial states
• NyxError

Constants

• AU
  Astronomical unit, in kilometers, according to the IAU.
• ECC_EPSILON
  If an orbit has an eccentricity below the following value, it is considered circular (only affects warning messages)
• MA_EPSILON
• SPEED_OF_LIGHT
  Speed of light in meters per second
• SPEED_OF_LIGHT_KMS
  Speed of light in kilometers per second
• SS_MASS
  Mass of the solar system from https://en.wikipedia.org/w/index.php?title=Special:CiteThisPage&page=Solar_System&id=905437334
• STD_GRAVITY
  From NIST special publication 330, 2008 edition, in meters per second squared
• SUN_GM
  GM of the Sun in km^3/s^2

Traits

• ParentRotation
• State
  A trait for generate propagation and estimation state. The first parameter is the size of the state, the second is the size of the propagated state including STM and extra items.
• TimeTagged
  A trait allowing for something to have an epoch

Functions

• assert_orbit_eq_or_abs
• assert_orbit_eq_or_rel
• try_achieve_b_plane
  Returns the Delta V (in km/s) needed to achieve the B Plane specified by B dot R and B dot T. If no LTOF target is set, this method will fix VX, VY and VZ successively and use the minimum of those as a seed for the LTOF variation finding. If the 3x3 search is worse than any of the 2x2s, then a 2x2 will be returned. This uses the hyperdual formulation of the Jacobian and will also vary the linearize time of flight (LTOF).
