  • SC-130 features a Tri-sensor antenna that provides a high system accuracy for the heading of your vessel

    Provides highly accurate heading data for Autopilot, Radar, ARPA, Scanning Sonar, Current Indicator, Chart Plotter, ECDIS and Autopilot
    ●0.25° (with SC-130)
    Ideal for medium to large vessels navigating in crowded ports and making precise maneuvers, such as berthing.
    ●0.4° (with SC-70)
    Ideal for small to medium boats requiring highly accurate heading .
  • Utilizes GNSS such as GPS, Galileo and GLONASS for high precision

    ・SBAS compatible (EGNOS,WAAS, MSAS)
    ・Provide precise data for SOG, COG, ROT and L/L
    ・Eliminating the problem of not having enough satellites at hand by using multiple types of satellites
  • Speed on 3 axis (Bow, stern and longitudinal) for safe navigating and berthing

  • Type-approved as THD, GPS and ROTI*. Complying with following requirements (For Solas Vessels)

    IMO MSC.116(73) •IMO MSC.112(73) •IMO MSC.526(13) •IMO A.694(17)
    IMO MSC.97(73) •IMO MSC.191(79) •IMO MSC.302(87) •IEC 60945 Ed.4

    IEC 61108-1 Ed.2 •ISO 22090-3 Ed.2 •ISO 20672 Ed.1
    * requires the RD-50 as a display unit
  • Easily integrated into the existing shipboard network via Ethernet

  • Rapid follow-up rate 40°/S

    ・Twice the IMO high speed craft requirement, 20°/s
  • Maintenance free and no recurring cost as there are no mechanical parts

  • Super short starting time - 90 seconds

    ・Once the power is on, it takes about 90 seconds only to start
    (The starting time will slightly differ depending on the equipment)
  • Easy to retrofit by using existing antenna cabling

    ・For SC-50/55/60/110/120 (The LAN_CNV option Kit is necessary)
  • Precision Pitch/Roll data in Analog and Digital formats for vessel stabilization, SONAR, etc.

  • Display modes

    THD mode

    - Display the heading (HDG) of the ship

    Speed mode 

    - 3-axis speed of the ship: Bow, Stern and longitudinal
    (non-IMO type only)

    ① Current selected mode (SPD or THD), integrity status and common satellite
    ②   Transverse speed at bow position
    ③   Longitudinal speed 
    Transverse speed at stern position
    ⑤   Distance travelled 

    Navigational data screen

    - 3-axis speed, as well as the Heading, Rate Of Turn and
    Course Over Ground can be Grasped at a glance 
    (non-IMO type only)

    GPS integrity mode 

    - GNSS (GPS,Galileo,GLONASS*) satellites signal reception
    including signal strength and signal to noise Ratio
    - SBAS signal status 
    *Type approved with GPS only

    ROTI mode 

    - Rate Of Turn Indicator displaying on the RD-50 (ROTI Display unit approved for SOLAS vessels)
