2. a The Meridian Gyrocompass applies dynamic tuning to settle automatically to the 16 meridian Due to the physical principles of a north seeking gyrocompass achievable accuracy depends on the operating latitude and the vessel dynamics To optimise its performance the Meridian Gyrocompass uses information supplied by external equipment for example a GPS receiver and a speed log to apply latitude and speed corrections Refer to Appendix A for a simplified explanation of the gyrocompass theory of operation 2 2 Technical data 2 2 1 Power Requirements Voltage 24V DC acceptable range 18V to 36V DC Power consumption 3A at power on 1 2A continuous The power supply capacity should exceed 200W CAUTION The Meridian Gyrocompass contains a non isolated PSU Therefore you should supply it with power from an SELV source as defined in IEC EN 60950 The power supply source should be switched and protected by a suitable circuit breaker To comply with the requirements of IMO Resolution A 821 19 Performance Standards for Gyrocompasses for High Speed Craft power to the gyrocompass should be delivered by an uninterruptable power supply for example the SGBrown UPS part number 929128 2 2 2 Performance definitions as in ISO 8728 Settle point error 0 35 sec latitude Static error 0 1 sec latitude RMS Dynamic accuracy 0 3 sec latitude Scorsby and Intercardinal motion tests Settle point repeatability 0 25 sec lati
