Advanced Marine Navigation with the SI-TEX SP-120C Autopilot

The SI-TEX SP-120C Autopilot is engineered to deliver precision steering for vessels equipped with hydraulic, mechanical, or solenoid-controlled steering systems. Designed for seamless integration, this autopilot does not require a separate junction box—everything connects directly to the rear of the control head. With an intuitive interface, vibrant color LCD display, and advanced navigation capabilities, the SP-120C enhances vessel control and efficiency for a smooth and effortless boating experience.

Intelligent Steering Technology

Equipped with a high-performance 9-axis rate gyro compass, the SP-120C ensures exceptional steering response. By utilizing GPS inputs, including Speed Over Ground (SOG) and Course Over Ground (COG), the system refines autopilot performance, making course adjustments smooth and precise. The autopilot also interfaces with most chart plotters through its NMEA-0183 GPS connection, enabling waypoint and route steering for seamless navigation.

User-Friendly Control Interface

The compact 4.1” x 4.1” control head is splash-proof and features an easy-to-read color LCD display. Designed with intuitive software, the autopilot allows quick heading selection, simplified operation, and straightforward setup, making it accessible for both seasoned mariners and new users alike.

Real-Time Data Display

The SP-120C provides real-time navigation data, displaying both the actual compass heading and selected heading simultaneously. Additionally, the rudder angle is displayed in real-time, giving users a complete overview of vessel control at a glance.

Seamless Integration and Connectivity

With NMEA-0183 output capability at 10kHz, the autopilot can send compass heading data to multifunction displays (MFDs) for chart and radar overlay applications. This enhances situational awareness and ensures the autopilot remains a vital component of a well-integrated marine navigation system.
