|
The SPS461 GPS Heading and Positioning Receivers are modular, dual-antenna systems for marine construction and hydrographic survey. It may improve accuracy by using DGPS via SBAS, OmniSTAR VBS, MSK Beacon or external RTCM DGPS corrections. The receiver is equipped with a single GA530 L1/L2/OmniSTAR/Beacon/SBAS antenna. Therefore heading, roll and pitch cannot be calculated. |

| Origin Description: | xyz-position of antenna from Alignment Survey Report RV Heincke (January 2016). Antenna located on observation deck, device located on bridge deck. | | X: | 39.6 m
(Positive X axis is forward and along the centerline of the vessel with X0 at the Stern point of the vessel. ) | | Y: | 2.129 m
(Positive Y axis is portside of centerline with Y0 at centerline at the Very stern point of the vessel. ) | | Z: | 16.433 m
(Positive Z axis is upwards of basis. Z0 is set to the hydrophone on midship.) |

Central geographical ship's position and time standard
Time synchronization is done by DShip receiving the data for logging. Still, the data itself contain GPS time information.
Rawdata storage on board
Data storage in DShip system.
