1. Nav-IS Combined Maritime Speed Log & Meteorological System

2. Combined Maritime Speed Log & Meteorological System AMI Marine UK sells and fully supports our speed logs and meteorological systems both individually and also in conjunction with SMIDS (Ships Movement Information Display System). The Nav-IS (Navigation Information System) is a cost effective combined system supplied to commercial maritime standards. Nav-IS exceeds the requirements of EN60945 & EN61023 and is compliant with IMO resolutions A.478 and A.824.

3. Main Electronics Unit (MEU) Combined Speed Log & Meteorological Functions. Modular construction to save cost. Provides power to log & meteorological sensors. Single or Dual Axis EM Speed Measurement. Auto wind sensor selection (most windward). Relative and True wind vector outputs. User selectable wind damping. Interfaces with Nav-IS Control & Display Unit. Processes and distributes navigation data. RS422 NMEA, Simulated Potentiometer (Volts/Knot), User selectable potential free contacts (PPM).

4. EM Probes Fixed Single or Dual Axis Flush Probes In-board Retractable Single or Dual Axis Flush Probes Fixed Protruding High Speed Probe Specified accuracy with flush probes: 0 to 10 Knots: ± 0.2 knots. Above 10 knots: ±2% Specified accuracy with protruding probes: 0 to 10 Knots: ± 0.1 knots. Above 10 knots: ±1%

5. Meteorological Sensors Ultrasonic Anemometer Speed: 0-65m/s (0-130kts) Accuracy: ±2% Direction: 0-359.9° Accuracy: ±2° Air Temperature & Humidity Sensor Air Pressure Sensor Module Sea Temperature Sensor Temperature: -40 to +70°C (+158°F) Accuracy: ±0.4°C Humidity: 0-100% RH Accuracy: ±4% RH Temperature: -5 to +45°C (+113°F) Accuracy: ±0.3°C Barometric Pressure: 500 – 1100 hPa Accuracy: 0.2hPa (25ºC) Integral to MEU with vented pipe to exterior of enclosure.

6. Control and Display Unit The optional Nav-IS Control & Display Unit provides clearly and concise display of all of the Nav-IS system functions. Can also be used to display many other ship's navigation parameters on multiple page formats, therefore alleviating the need for addition dedicated displays.

7. Control and Display Unit The unit is also necessary to provide occasional control of the system including simulated LOG speed entry and one-time calibration table entry. Alternatively a windows based software package is available for use on a laptop or navigation bridge system.

8. Summary Combined Speed Log & Meteorological Functions. Cost effective modular construction. Single or Dual Axis EM Speed Log. Complete range of Meteorological sensors including Wind, Air Temperature, Humidity, Air Pressure, Sea Temperature. High accuracy. Low maintenance (Solid-State Sensor Technology). Versatile Control & Display Unit for clear and concise display of all of the Nav-IS system functions as well as many other ship's navigation parameters on the one compact unit.
