SATELLITE COMPASS™ (GPS COMPASS) Model SC-70

Features

• SC-70 provides a high system accuracy for the heading of the ship

  Provides highly accurate heading data for Autopilot, Radar, ARPA, Scanning Sonar, Current Indicator, Chart Plotter, ECDIS and Autopilot
  ●0.25°rms (with SC-130)
  Ideal for medium to large vessels navigating in crowded ports and making precise maneuvers, such as berthing.
  ●0.4°rms (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 the IEC, ISO 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 62288 Ed.2 •IEC 61162-1 Ed. 4 •IEC 61162-2 Ed.1 •IEC 61162-450 Ed.1
  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 45°/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 location)

• 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.
