| Definition | The JLR-21 is a GPS compass which provides heading, roll, pitch, rate of turn, and heave information. The system is also known as a 3D Dynamic SensorTM, designed to provide accurate information of the ships movement in all axes. The system includes a 5.7-inch high-visibility display with several display modes enabling operation in low-light settings. The system processor is built into the antenna and has a startup time of less than 2 minutes. In rough ocean conditions the GPS compass can correct up and down (attitude) movement, compensating high waves with 20 cm route mean square (rms) accuracy, useful for fish finder and sonar applications. The JLR-21 also supports speed and course over ground (SOG and COG), with position updated every 200 milliseconds. The JLR-21 features high speed tracking response (rate of turn 45 degrees/second), and dynamic heading, roll, and pitch accuracy of 0.5 degrees rms. Positional accuracy is 12 metres, 2 degrees rms with GPS, 6 metres, 2 degrees rms when corrected with SBAS, or 4 metres, 2 degrees rms when differential GPS (DGPS) corrected. | ||
