Info

● Setting mode MANUAL : This operation sets the frequency and baud rate of the beacon receiver. This allows receipt of DGPS at an early stage but receipt is not possible unless the ship is in the beacon receipt area that is set. AUTO : Automatic search of the beacon transmission station is undertaken for receipt. Time is required for this search. (a) Select "DGPS" in the line "GPS PRESET" - the menu "INITIAL SETTING 1". The menu "DGPS PRESET" will appear. (b) Select the items in the cross key and change the set value using the RANGE key. Changing "N/S" and "E/W" of the ship's position is also set pushing the "▲ (up)" or "▼ (down)" on the RANGE key. (c) Push the ENTER key. The setting has been determined. (d) Select "SEND DATA" in the menu "DGPS PRESET". The DGPS setting will be implemented. 3. Status of reception of GPS and DGPS This operation displays the status of reception of the GPS receiver and DGPS receiver. (a) Select "CONDITION" in the line "GPS PRESET" - the menu "INITIAL SETTING 1". The status of reception of the GPS receiver and DGPS receiver will be displayed. The display of the reception status of GPS will display the conditions of the following items only when the sensor type receiver such as JLR-4310 is connected and operating normally. ● Items Ship position : When the ship's position is determined, the latitude and longitude of the position will be displayed. GPS internal time : The world time as measured by the GPS receiver will be displayed. Altitude : The altitude of the ship will be displayed. However, when the fix mode is 2D (two dimension), the height of the antenna that was input at initial setting will be displayed. DOP : The precision of the results of the measurement will be displayed. If the value is 20 or above, the precision is poor. 260
Reception satellite : The number of the satellite used for the measurement will be displayed. Bearing, elevation angle : The bearing and elevation angle of the satellite will be displayed. Signal strength : The strength of the signal of the satellite from which signals are being received will be displayed. If the value is 20 or less, the satellite may not be usable for measurements. The following items will be displayed only when a beacon receiver is connected and operating normally. ● Items Frequency : The frequency of the beacon station from which signals are being received will be displayed. Baud rate : The baud rate of the beacon station from which signals are being received will be displayed. RSSI : The reception strength of the beacon station from which signals are being received will be displayed. If the value is 100 or less, the beacon may be not possible to receive signals. 261
