_SbgEComLogShipMotion Struct Reference

#include <sbgEComLogShipMotion.h>

Data Fields
uint32_t	timeStamp
uint16_t	status
float	mainHeavePeriod
float	shipMotion [3]
float	shipAccel [3]
float	shipVel [3]

Detailed Description

Structure storing data for the SBG_ECOM_LOG_SHIP_MOTION or SBG_ECOM_LOG_SHIP_MOTION_HP message.

Ship motion measurements are defined in a vessel-specific coordinate frame:

• Surge: Longitudinal displacement (positive toward the bow/forward).
• Sway: Transverse displacement (positive toward the starboard side/right).
• Heave: Vertical displacement (positive downward).

Note: Always check the status flags before using the data, as they indicate the validity of each output. Some data fields, such as the heave period or surge/sway components, may be unavailable in certain frames.

Field Documentation

timeStamp

uint32_t _SbgEComLogShipMotion::timeStamp

Time in microseconds since sensor power-up.

status

uint16_t _SbgEComLogShipMotion::status

Status bitmask indicating validity of ship motion data.

mainHeavePeriod

float _SbgEComLogShipMotion::mainHeavePeriod

Dominant heave period in seconds.

shipMotion

float _SbgEComLogShipMotion::shipMotion[3]

Surge, sway, and heave positions in meters.

shipAccel

float _SbgEComLogShipMotion::shipAccel[3]

Surge, sway, and heave accelerations in m.s^-2.

shipVel

float _SbgEComLogShipMotion::shipVel[3]

Surge, sway, and heave velocities in m.s^-1.
