Furuno SC702 Display Unit User Manual

1. ບົດແນະນຳ

The Furuno SC702 is the display unit component of the SC70/SC130 Satellite Compass system. This system utilizes advanced GNSS (Global Navigation Satellite System) technology, including GPS, Galileo, and GLONASS, to provide highly accurate navigation data. The SC702 display unit presents critical information such as heading, speed over ground (SOG), course over ground (COG), and rate of turn (ROT), essential for safe and precise vessel operation. This manual provides detailed instructions for the setup, operation, and maintenance of your SC702 display unit.

The main display screen provides real-time navigation data. Key indicators include:

• SPD (ຄວາມໄວ): Displays the vessel's speed, typically Speed Over Ground (SOG).
• HDG (Heading): Shows the vessel's current heading in degrees, relative to true north.
• ROT (Rate Of Turn): Indicates how quickly the vessel is changing its heading, in degrees per minute.
• COG (Course Over Ground): Displays the actual direction of the vessel's movement over the ground.
• ແກ້ໄຂ: Indicates the GPS fix status (e.g., GP-3D for 3D GPS fix).
• PDOP: Position Dilution of Precision, an indicator of GPS accuracy. Lower values are better.
• COM.SV: ຈໍານວນດາວທຽມໃນ view.
