||An all-in-view satellite compass providing accurate attitude information for navigation equipment, such as radar, plotter, autopilot, automatic identification system (AIS), fish finder, and sonar. The SC-30 delivers heading, roll, pitch, heave, GPS position, speed over ground, course over ground, and rate of turn information. The SC-30 employs a 2-antenna system that calculates a single vector, while a 3-axis rate gyro and acceleration sensors add the second vector. This configuration enables the SC-30 to calculate highly accurate roll and pitch data without using a third sensor. The GPS receiver features 12 discrete channels, with an L1 receiving frequency of 1575.42 MHz, and one Satellite Based Augmentation System (SBAS) channel. Attitude accuracy of 0.5 degrees RMS (heading/pitch/roll). Positional accuracy of 10 m (95%) GPS or 3 m (95%) WAAS.
