All Implemented Interfaces:

```
public class AttitudeDetermination
extends CommentsContainer
```
Attitude determination data.
Beware that the Orekit getters and setters all rely on SI units. The parsers and writers take care of converting these SI units into CCSDS mandatory units. The Unit class provides useful fromSi and toSI methods in case the callers already use CCSDS units instead of the API SI units. The general-purpose Unit class (without an 's') and the CCSDS-specific Units class (with an 's') also provide some predefined units. These predefined units and the fromSi and toSI conversion methods are indeed what the parsers and writers use for the conversions.
