[. . . ] RC400 GPS Chartplotter Owner's Handbook Document Number: 81237-2 Date: August 2004 ii RC400 GPS Chartplotter iii About this Handbook Introduction This handbook describes the RC400 Portable GPS Chartplotter. The RC400 utilizes Satellite Differential (SD) signals for enhanced navigational accuracy. The RC400 GPS Chartplotter can be used portably with the supplied NiMH batteries or fix-mounted while connected to ship's power. The equipment is comprised of: · 4 in Color LCD display with Chart holder compartment for a Navionics Gold Chart electronic chart card · Internal GPS antenna · Battery tray for portable operation ® The RC400 GPS Chartplotter can output GPS and Waypoint data to operate with other equipment, such as an autopilot or repeater instrument connected via the NMEA 0183 interface. [. . . ] An offset of 2nm or less is applied to all position data equal to the range and bearing between the WGS 84 position and the position entered. Note: Pressing ENTER with a selected offset of more than 2nm gives a warning message which is cleared on any key press. The Calibration Set Up mode maintains and the user can either reselect an acceptable offset or press CLEAR to reset the value to zero and return to the Set Up menu. 4. 4 GPS Setup The GPS set up page provides information for the status of the tracked navigation satellites plus HDOP and satellite Fix Status. It also provides the ability to select the SD satellite and to reset the GPS system. To select GPS Set Up: 1. Use the trackpad to highlight the GPS SET UP function and press ENTER to display the GPS STATUS screen and soft key. GPS STATUS is displayed. 44 RC400 GPS Chartplotter GPS STATUS 0 0 0 0 0 0 0 0 0 0 0 122 HDOP 0 FIX STATUS 1. 0 SD-GPS ENABLE RESET GPS SD-FIX D6250-1 D6253-2 Figure 4-3: GPS Status Screen and Soft Key The GPS STATUS screen provides, for each tracked satellite, the satellite number, a graphical signal strength bar, status, azimuth angle and its elevation angle from your vessel. Positional accuracy is dependent upon these parameters; in particular, the azimuth and elevation angles are used in a triangulation process to calculate your position. HDOP (Horizontal Dilution Of Position) is a measure of this accuracy; a higher figure signifies greater error. The Fix Status can indicate: · · · SD-FIX, where a Satellite Differential fix has been acquired FIX OK, where a normal GPS fix has been acquired NO FIX, where no satellite fix can be acquired Chapter 4: Setting Up 45 To enable or disable SD-GPS mode. 1. Using the trackpad left/right highlight SD-GPS in the function bar. SD-GPS ENABLE RESET GPS D6253-2 2. · Select ON to allow the unit to use SD corrections if available. · Select OFF to force the unit to calculate a normal GPS fix with no satellite GPS corrections. Press CLEAR twice to return to the normal display. To reset SD-GPS. 1. Using the trackpad left/right highlight RESET GPS in the function bar and press ENTER. Press CLEAR twice to return to the normal display. 46 RC400 GPS Chartplotter Chapter 5: Operation 47 Chapter 5: Operation 5. 1 Introduction This chapter explains how to use the chart functions to navigate with the RC4300. 5. 2 Working with Waypoints The RC400 enables you to place up to 500 waypoints. A waypoint is a position entered on a chart as a reference or destination point. All waypoints placed on the chartplotter are stored in a waypoint database list which includes symbol, position, bearing, range, date and time. All waypoints in the database are displayed on screen, unless the SHOW WAYPOINTS is set to OFF in the Chart Set Up menu, as described on page 40. A waypoint can be selected, either on-screen or from the list, for editing. Waypoints can be placed either using the cursor, or at the vessel's position, or at a specific lat. /long. Waypoints can also be placed before the chartplotter is installed on your vessel. When a new waypoint is placed, it is displayed using either the default symbol of a cross or an alternative symbol available from the Chart Set Up menu, as described in Chapter 4.
