| Definition | An all-in-view satellite compass providing accurate attitude information for navigation equipment. The SC-50 receives and provides both positional and platform attitude information and displays these on an LCD screen. The SC-50 employs a 3-antenna system and delivers GPS positioning, speed and course over ground, rate of turn, pitch and roll angle. Ship's heading is determined by decoding the phase data in the GPS carrier frequency. When a pair of antennas, each connected with an associated GPS engine and processor, are installed along the ship's fore-aft line, the GPS systems at each calculate the range and azimuth to the satellite. The addition of the third antenna to make a tri-antenna system helps to reduce the influence of vessel motion. The GPS receiver features 12 discrete channels, with an L1 receiving frequency of 1575.42 MHz. Heading accuracy is 0.5 degrees RMS, GPS fix is to within 10 m (95%), DGPS fix is to within 5 m (95%), and WAAS fix is to within 3 m (95%). Follow-up is 45 degrees per second rate-of-turn. Settling time is 3 minutes. | ||
