- GNSS Position, 127250 - Vessel Heading, and
128259 - Water Speed
(If a Heading Sensor and Water Speed Sensor are
not present, a less-accurate reading can be calculated
using only the Wind Sensor and GPS antenna

202 - GNSS Position]
)
(If a GPS antenna is not present, a less-accurate
reading can be calculated using only the Wind Sensor,
Water Speed Sensor, and Heading Sensor [006
- Wind Data, 2720 - Vessel Heading, and 22
- Water Speed])
