Description
The Marinelite SC90 / SC901 Satellite Compass is a next-generation high-precision heading system designed for marine vessels requiring reliable GPS-based navigation in all sea conditions. Equipped with carrier phase decoding technology, the system provides extremely accurate orientation, even during rapid vessel turns, pitch, or roll.
Using a dual-star navigation system (GPS + Beidou), the SC90 delivers faster directional speed, stable heading data, and superior signal tracking. With a built-in gyro compensation system, the compass achieves heading updates up to 50 times per second, with turn-rate performance reaching 90°/s – meeting advanced requirements for high-speed vessels.
The SC90 supports multi-channel NMEA0183 data output for full connectivity with radar, ARPA, ECDIS, AIS, chart plotters, autopilots, sonar, and all major marine navigation systems. Its industrial-grade design ensures durability, while the optional 5-inch full-touch display provides intuitive data visibility and multiple display modes.
Certified by China Classification Society (CCS), the Marinelite SC90/901 is maintenance-free, with no moving parts and no recurring service cost.
