/**
 *
 * 	Contains the home position.
 * 	The home position is the default position that the system will return to and land on.
 * 	The position must be set automatically by the system during the takeoff, and may also be
 * explicitly set using MAV_CMD_DO_SET_HOME.
 * 	The global and local positions encode the position in the respective coordinate frames, while
 * the q parameter encodes the orientation of the surface.
 * 	Under normal conditions it describes the heading and terrain slope, which can be used by the
 * aircraft to adjust the approach.
 * 	The approach 3D vector describes the point to which the system should fly in normal flight mode
 * and then perform a landing sequence along the vector.
 *         Note: this message can be requested by sending the MAV_CMD_REQUEST_MESSAGE with
 * param1=242 (or the deprecated MAV_CMD_GET_HOME_POSITION command).
 *       
 *
 * @param latitude Latitude (WGS84)
 * units = degE7
 * @param longitude Longitude (WGS84)
 * units = degE7
 * @param altitude Altitude (MSL). Positive for up.
 * units = mm
 * @param x Local X position of this position in the local coordinate frame (NED)
 * units = m
 * @param y Local Y position of this position in the local coordinate frame (NED)
 * units = m
 * @param z Local Z position of this position in the local coordinate frame (NED: positive "down")
 * units = m
 * @param q 
 *         Quaternion indicating world-to-surface-normal and heading transformation of the takeoff
 * position.
 *         Used to indicate the heading and slope of the ground.
 *         All fields should be set to NaN if an accurate quaternion for both heading and surface
 * slope cannot be supplied.
 *       
 * @param approachX Local X position of the end of the approach vector. Multicopters should set this
 * position based on their takeoff path. Grass-landing fixed wing aircraft should set it the same way
 * as multicopters. Runway-landing fixed wing aircraft should set it to the opposite direction of the
 * takeoff, assuming the takeoff happened from the threshold / touchdown zone.
 * units = m
 * @param approachY Local Y position of the end of the approach vector. Multicopters should set this
 * position based on their takeoff path. Grass-landing fixed wing aircraft should set it the same way
 * as multicopters. Runway-landing fixed wing aircraft should set it to the opposite direction of the
 * takeoff, assuming the takeoff happened from the threshold / touchdown zone.
 * units = m
 * @param approachZ Local Z position of the end of the approach vector. Multicopters should set this
 * position based on their takeoff path. Grass-landing fixed wing aircraft should set it the same way
 * as multicopters. Runway-landing fixed wing aircraft should set it to the opposite direction of the
 * takeoff, assuming the takeoff happened from the threshold / touchdown zone.
 * units = m
 * @param timeUsec Timestamp (UNIX Epoch time or time since system boot). The receiving end can
 * infer timestamp format (since 1.1.1970 or since system boot) by checking for the magnitude of the
 * number.
 * units = us
