Constructor Details

HermiteInterpolatedAttitudeDataServer

protected HermiteInterpolatedAttitudeDataServer(long tStart,
 Duration tLength)

Constructor for a given start time and mission length

Parameters:

tStart - start time of the valid attitude interval

tLength - length of the valid attitude interval

Method Details

initialize

public abstract void initialize()
                         throws RuntimeException

Description copied from class: NumericalAttitudeDataServer

Any numerical attitude needs to be initialized

Specified by:

initialize in class NumericalAttitudeDataServer<IAttitude>

Throws:

RuntimeException - initialization fails

See Also:

• This method will compute the attitude and attitude rate at discrete points and store in the arrays tNs, qX, rateX, etc

getAttitudeNative

public IAttitude getAttitudeNative(long t)
                            throws RuntimeException

Description copied from class: BaseAttitudeDataServer

Evaluate the attitude in the native time system of the server

Specified by:

getAttitudeNative in class BaseAttitudeDataServer<IAttitude>

Parameters:

t - - the time elapsed since the epoch of J2010 in ns (TCB)

Returns:

attitude for the given time

Throws:

RuntimeException
