| Definition | A vessel gyrocompass originally designed and developed by SG Brown, now sold by Teledyne TSS. It measures vessel attitude, heading, pitch and roll. The Meridian Standard gyrocompass can be installed as a stand-alone unit or, together with any of the TSS range of repeaters and ancillaries, it becomes a single, dual or triple gyro system. The Meridian can also be used as a retrofit unit. It features a free-spinning dynamically tuned gyroscope (DTG) which uses gravity control and Earth rotation to align the gyroscope spin axis with the meridian, i.e. the true north direction. It is available as a higher performance unit (Meridian Surveyor) offering greater heading accuracy. It also features a large array of digital and analogue outputs managed via the remote control unit. The Meridian Standard has a static heading accuracy of 0.1 degrees secant latitude RMS (static) and 0.3 degrees secant latitude RMS (dynamic). Its settle point error and repeatability is 0.25 degrees secant latitude. It operates between 80 degrees N and 80 degrees S and at ship speeds between 0 - 90 knots. | |
