contenttypeSummary

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.

Components

The GPS receiver is installed on the bridge deck. The antenna is installed on the observation deck.

In the registration lab an NMEA stream of GPS records can be received. 4 sockets of RS232 type (DSub9) with following setting are available: 4800 Baud, No Parity, 8 Data Bits, 1 Stop Bit.
NMEA records of type $GPGGA, $GPVTG, $GPZDA, $GPRMC, $GPGLL are provided with 1 Hz.

Additionally a computer is installed receiving T02 data from this sensor. These data are used to calculate GPS tide. Three different services are available: 1=Uncorrected, 2=Ultra-rapid and 3=Rapid/Final. GPS tide is provided as two column file (date/time, height) to be used by multibeam echo sounder. See more details in Heincke_GPS_Tide_v20191016.pdf.
