Simrad SP90

851-164510 / Rev.E

8.4 (D)GPS connection

A (D)GPS may be connected to the SP90 sonar to indicate the

latitude and longitude position of the vessel, cursor, markers and

targets. In addition to the navigational data, the (D)GPS may

also be used for the input of the speed log information. Most

(D)GPS systems are equipped to present the course information,

but this data is generally too inconsistent to provide a stable

sonar presentation.

The sonar can read the (D)GPS data from an RS-232 serial line

with a standard NMEA 0183 telegram format.

For connection to the (D)GPS log, refer to the applicable

(D)GPS documentation.
