Coord EECFI::Attitude::changeFrame ( const SatId &  satId,
const ModelId &  modelId,
long  modeFlag,
long  frameFlagIn,
long  frameIdIn,
long  frameFlagOut,
long  frameIdOut,
const StateVector &  satStateVec,
const Coord &  stateVec 
) throw (CfiError)

Change the input vector/direction from a coordinate system to another ( including attitude frames ).

This method changes the coordinate or attitude frame of a location or direction by keeping the location or direction in inertial space identical. Both all coordinate frames and all attitude frames are supported. When changing the frame for a location, the difference in origin of the frames is taken into account. While when changing the frame for a direction, the target is assumed to be at infinity.

Parameters:
satId Satellite id.
modelId Model id.
modeFlag Selection of location or direction calculus (ModeFlagPointingEnum).
frameFlagIn Selection of coordinate or Attitude frame on input (FrameFlagEnum).
frameIdIn Coordinate frame id or attitude frame id on input (AttFrEnum or CsRlEnum).
frameFlagOut Selection of coordinate or Attitude frame on output (FrameFlagEnum).
frameIdOut Coordinate frame id or attitude frame id on output (AttFrEnum or CsRlEnum).
satStateVec State vector with time, time reference, position, velocity and acceleration of satellite (Earth fixed CS).
stateVec Coordinates to be transformed in input frame (deriv indicates if pos, pos and vel or pos, vel and acc is to be calculated).
Returns:
Tranformed coordinates in ouput frame.

void EECFI::Attitude::compute ( const ModelId &  modelId,
const StateVector &  stateVector,
long  targetFrame 
) throw (CfiError)

Compute attitude matrix.

This method calculates the Attitude Frame for a given S/C state vector.

Parameters:
modelId Model Id.
stateVector State vector which contains time reference, time, position, velocity and acceleration needed for computation.
targetFrame Attitude frame (AttFrEnum).
AttitudeData EECFI::Attitude::getData (  )  const throw (CfiError)

Get attitude id data.

Returns:
Attitude data.

GenericId * EECFI::Attitude::getId (  )  [protected]

Get the id.

Returns:
Pointer to xo_orbit_id.
Attitude const & EECFI::Attitude::operator= ( Attitude const &  att  )
