Description

NavPak CE is a chart plotter with GPS and AIS interface which runs on tablet or Panel computers using the Windows CE operating system.  It is compatible with Softchart, NDI, BSB,  USGS DRG Topographical maps, scan-your-own charts or maps, and S-57 ENC vector charts. This edition has been compiled to run on Windows CE (version 3 or later), on computers using Intel and ARM compatible CPUs'. Minimum recommended requirements are 64 MB of RAM, and 200 Mhz CPU speed.

The screen shot above, shows a typical navigation scenario.  Your position is shown as a flashing red circle.  Your past track is the red line with small circles at the track points.  The active waypoint and route-leg flash magenta and cyan.  Inactive way points and route legs are green.  The heading predictor line and range rings flash, and a line flashes between your position and the active way point.  The information in the title bar can be configured to show: latitude and longitude, course and speed, range, bearing and VMG to the active way point, or compass heading and speed.

 

If you prefer to keep things simple, you can use NavPak without way points or tracks and just use it with a GPS as shown below:

The screen shot above shows the GPS position, Predictor Line, and a Range Ring on an ENC chart.  The Predictor Line uses Course Over Ground (COG) from the GPS to show your course, or if you are using AIS input, and the AIS is connected to a compass, then the Predictor Line can be set in the Configuration to use the heading from the compass.

 

NavPak CE can be used alone, or in conjunction with NavPak Professional Edition (Demo or Registered copies). Using the NavPak Pro demo on your laptop or desktop computer you can view your charts, plan routes and waypoints, draw Overlays, and then copy all this to your handheld computer running Windows CE. After your voyage, you can view the track generated by NavPak CE on your desktop or laptop computer.

Charts

When you start NavPak CE, it searches all the storage cards in your handheld computer for compatible charts, and then plots the outlines of the charts as magenta polygons.  It also identifies the smallest scale chart as the parent chart. 

 

On the Parent Chart, you can quickly verify your chart coverage and select an individual chart by tapping inside the outline. The outline is highlighted and the dialog box: Identified Chart appears as shown above. If there is more than one chart where you tapped, you can use the up-down arrows in the dialog box to highlight the other chart outlines. You can also automatically open a chart based on your GPS position. You can mix charts of various formats in the same folder, and all are quickly accessible using the menu and tool bar.

 

When using ENC vector charts, you can quickly retrieve object info as shown below:

Vector charts are made of point, line, and polygon objects. When you tap on an object on the main window, the name is shown in the Object List in the Feature Info dialog box. If you tap on the name in the list, the item is highlighted in the list and on the main window and the attributes are shown. In the case above, it is a depth contour line.

 

Sometimes, more than one object is found at the point where you tapped and these will be shown on the Object List in the box. When you tap on an object name in the list, the attributes and notes will be shown in the dialog box when available.

 

Charts and objects can be searched by single tap or double tap. If you single tap and then select the Query button , the box on the left will appear. If you double tap when a raster chart is displayed, the box in the center will appear, and if you double tap when a vector chart is displayed, then the box on the right will appear. In all cases, the last tap is used to identify items and as the center point for zooming.

 

When you tap inside a chart boundary, it will turn green, then it can be opened, or you can see the title and file name.  The parent chart can be opened by menu selection to see the outlines of the other charts, and you can open charts and maps by file name with the Open Chart File dialog box.

 

User Interface

NavPak CE can be used with a stylus, keyboard, mouse, and\or finger on a touch screen device. The text items on the left side of the menu bar are drop down menus, and the buttons in the center and on the right are for frequently used functions.

 

The Area Map, shown on the left, is a miniature picture of the whole chart.  When you tap the stylus on the Area Map, the main window will scroll to the point indicated.  This allows you to move around the chart or map very quickly.  You can also drag the stylus on the main window to scroll, or you can use the arrow keys on the computer. 

You can open and close the Area Map using the button on the Tool Bar or by selecting Area Map on the menu.

 

Feature List

Plots your position and track on the chart. Save track on disk as a voyage log. Each track point contains position, time, date, speed, and course. Also you can add names and notes to each track point.

Automatically scrolls chart and loads next chart as your position moves. Accurately handles skewed and odd shaped charts while traveling at high speed.

AIS interface plots AIS targets on the screen. Click on an AIS target to show detailed information.

Read, write and edit way points, and provide dynamic course and distance to a way point. Save way points and routes to pre-plan a voyage, or mark a position while underway.

Displays speed (SOG), course (COG), and Velocity Made Good (VMG), updated every 2 seconds.

Two Range Rings, Proportional Ship Rectangle, and Predictor Line.

Plot bearings and lines relative. Bearings can be used to triangulate your position without a GPS. Lines relative simulate a traditional Maneuvering Board, and DR positioning.

Measure distance and direction. Easy point and click operation.

Graphical user interface is very easy to use while very fast and capable.

Tap on a track point, way point, AIS target, or inside a chart outline, and the Search function will pop-up a dialog box with information about the item. This keeps all the necessary information easily accessible without a cluttered screen.

Celestial sight reduction and plotting. Star and Planet identifier.

Plot great circles and rhumb lines and advance LOPs with simple point-and-click operation.

Simulator function. Simulates GPS and can be used as a DR tracking calculator.
