Satellite Compass
A satellite compass is a navigation instrument that uses signals from Global Navigation Satellite Systems (GNSS) to determine a vessel’s heading with high accuracy. Unlike traditional magnetic or gyro compasses, it calculates heading by measuring the relative positions of multiple GNSS antennas installed on the vessel. This method eliminates errors caused by magnetic interference or gyro drift, making it highly reliable in all conditions. Satellite compasses provide additional data such as position, speed over ground, and course over ground, and they often integrate seamlessly with other navigation systems like ECDIS, radar, and autopilot. They are maintenance-free compared to gyro compasses, require no periodic calibration, and deliver consistent performance even in high-latitude regions where magnetic compasses are less effective. These systems are widely used on modern ships for precise navigation, dynamic positioning, and compliance with IMO standards.
Furuno SC70/SC130
The Furuno SC70 and SC130 are advanced satellite compasses designed for precise heading and position data using GNSS technology. Both models provide highly accurate heading information without the need for a gyro compass, making them ideal for modern navigation systems.
The SC70 is a compact, cost-effective solution suitable for small to medium-sized vessels. It uses dual GNSS antennas to calculate heading and offers additional data such as position, speed over ground, and course over ground. It integrates easily with ECDIS, radar, AIS, and autopilot systems, ensuring seamless connectivity. The SC70 is maintenance-free, requires no calibration, and delivers consistent performance even in high-latitude regions where magnetic compasses are less reliable.
The SC130 is designed for larger vessels and demanding applications. It features a three-antenna system for superior accuracy and faster response, providing heading precision within ±0.25° under normal conditions. It also offers advanced functionality such as roll, pitch, and heave measurements, which are essential for dynamic positioning and offshore operations. Like the SC70, it integrates with bridge systems and complies with IMO standards, making it suitable for SOLAS vessels.
Both models are rugged, weatherproof, and built for harsh marine environments. They eliminate errors caused by magnetic interference or gyro drift, reduce maintenance costs, and enhance overall navigation safety and efficiency.
