BeidouMeo

public BeidouMeo(AbsoluteDate validityStart,
                 AbsoluteDate validityEnd,
                 ExtendedPVCoordinatesProvider sun,
                 Frame inertialFrame)

Simple constructor.

Parameters:

validityStart - start of validity for this provider

validityEnd - end of validity for this provider

sun - provider for Sun position

inertialFrame - inertial frame where velocity are computed

Method Detail

correctedYaw

protected TimeStampedAngularCoordinates correctedYaw(org.orekit.gnss.attitude.GNSSAttitudeContext context)
                                              throws OrekitException

Compute GNSS attitude with midnight/noon yaw turn correction.

Specified by:

correctedYaw in class AbstractGNSSAttitudeProvider

Parameters:

context - context data for attitude computation

Returns:

corrected yaw, using inertial frame as the reference

Throws:

OrekitException - if yaw corrected attitude cannot be computed
