Class SunEstimationNavigationSoftwareChain

Namespace
NominalSystems.Classes
Assembly
NominalSystems.Classes.dll

This software chain is able to use the coarse sun sensor constellations, that may exist on the spacecraft, to estimate the direction that the sun is is based on the sensors and an Extended Kalman Filter (EKF). This will produce a more realistic estimate of spacecraft attitude than a typical simple navigator will. The translation, however, is just used from the simple navigator module.

public class SunEstimationNavigationSoftwareChain : NavigationSoftwareChain
Inheritance
SunEstimationNavigationSoftwareChain

Constructors

SunEstimationNavigationSoftwareChain()

Default constructor

protected SunEstimationNavigationSoftwareChain()

Fields

Out_GuidanceSunEstimationNavigationMsg

Defines the configuration for this software chain.

public GuidanceSunEstimationNavigationMessage? Out_GuidanceSunEstimationNavigationMsg

Field Value

GuidanceSunEstimationNavigationMessage

Methods

Configure()

The configure function must be implemented which will be used whenever the configuration should be reconnected and developed.

public override void Configure()

GetNavigationAttitudeMessage()

Returns the output navigation attitude message coming from the navigation chain.

public override NavigationAttitudeMessage? GetNavigationAttitudeMessage()

Returns

NavigationAttitudeMessage

The navigational attitude message

GetNavigationTranslationMessage()

Returns the output navigation translation message coming from the navigation chain.

public override NavigationTranslationMessage? GetNavigationTranslationMessage()

Returns

NavigationTranslationMessage

The navigational translation message

OnCreate()

Called when the object is created from the controller and has been attached to the parent object. By this point, it has been registered to the simulation and will run after the constructor.

protected override void OnCreate()

OnLoad(double)

Called after all of the data has been loaded from a save state on this object. This enables any post-load operations to be performed and extra data to be loaded from the metadata.

protected override void OnLoad(double time)

Parameters

time double

[s] The current clock time of the simulation
