| Interface | Description |
|---|---|
| Attitude |
This is the basic interface for all attitude representations and scanning
laws.
|
| Class | Description |
|---|---|
| AbstractAttitudeAnglesRates |
A little helper class to hold a set of three angles and associated rates.
|
| AnalyticalAttitudeDataServer |
This abstract class defines the fields and implements the methods that any
analytically defined attitude (e.g., NSL or EPSL) need in addition to those
in the superclass.
|
| AttitudeConverter |
Convert a given set of heliotropic angles into a quaternion
|
| AttitudeIntervalBean |
A bean that holds the attitude and its activation time.
|
| AttitudeXmlParser |
Parses the XML files with the attitudes and their activaton times into a binary search tree.
|
| BaseAttitudeDataServer<A extends Attitude> |
Common base class for all attitude data servers.
|
| ConcreteAttitude |
This class implements the Attitude interface and contains just the minimum
fields necessary to define a unique attitude at a given time, plus a large
number of methods to compute quantities that depend only on this attitude and
time.
|
| Epsl |
Implementation of the Ecliptic Pole Scanning Law (EPSL)
|
| EpslAndNsl |
This class implements a combination of the Ecliptic Pole Scanning Law (EPSL)
and the Nominal Scanning Law (NSL), by switching from EPSL to NSL at the
reference epoch (tRef).
|
| EquatorialAnglesRates |
A compound object for holding equatorial angles and their rates as per
Fig.
|
| GaiaAttitudeServer |
Provides caching of the last Nsl37 attitude requested.
|
| HeliotropicAnglesRates |
A compound object for holding heliotropic angles and their rates as per
Fig.
|
| HermiteInterpolatedAttitudeDataServer |
This abstract class contains the fields needed to store numerical attitude in
the form of arrays (q and SRS rates), and a method to calculate the attitude
for any given time using cubic Hermite interpolation
|
| ModifiedScanningLaw |
Class to generate Gaia Modified Scanning Law (MSL).
|
| MslAttitudeDataServer |
This class implements the Modified Scanning Law (MSL) by Hermite
interpolation of the attitude quaternion among values obtained by numerical
integration of the basic equations in heliotropic angles.
|
| Nsl37 |
Improved analytical representation of the Gaia Nominal Scanning Law (NSL).
|
| NslUtil |
Class with various static methods for analytical scanning laws.
|
| NumericalAttitudeDataServer<A extends Attitude> |
This abstract class defines the fields and implements the methods that any
numerically defined attitude need in addition to those in the superclass.
|
| Satellite |
Clone of the Satellite class in GaiaParams with very few needed parameters.
|
| TransitionScanningLaw |
| Enum | Description |
|---|---|
| Epsl.Mode |
Ecliptic pole scanning has two modes: PRECEDING (revolving phase angle =
0) and FOLLOWING (revolving phase angle = 180 deg).
|
| FOV |
FOV enumeration
|
| ModifiedScanningLaw.ScanState |
There are three modes of scanning, enumerated by the ScanState: NOMINAL =
running as in NSL, MODIFIED = running at reduced precession speed,
TRANSITION = the precession speed is ramping up or down between the
NOMINAL and MODIFIED states.
|
| ModifiedScanningLaw.TransitionFunction |
Enumerates the various transition functions tested.
