3.4.3.2 Input data
The Processing Unit has up to five ports for input of data. The following data can be input to
the system:
•
DGPS corrections. These corrections are normally input through com10. The data format
must conform to [2] "6 of 8" or "8 of 8" format. If additional lines are needed, use spare
lines in the range com5 to com9. Make sure that the same line is not specified for two
purposes. Optionally, the additional input lines on the AUX - Serial port can be used.
•
Heading data from an external source, for example a gyro compass, as backup to improve
reliability. Heading is normally input through the port com9. The data format must
conform to an [1] HDT message or a supported proprietary format.
If DGPS correction data from more than one reference station are available on the links,
Seapath combines data from up to six reference stations to obtain the best solution. If data
from more than six stations are available, the six nearest stations are used. If required, see the
description in the
User's Manual
[3] chapter five, "Operating Instructions" on how to override
the automatic selection of the six nearest stations.
