Portable Navigator III is a different kind of chart plotting and data logging system for navigation, pilotage and survey use in hydrographic and also terrestrial applications. It can be run on the smallest Notebook PC for field use or larger Desktop systems, under Windows from 95 to XP. Portable Navigator is ideal for survey work because it enables users to create and update their own detailed vector charts of the area and to quickly lay down track lines for navigation coverage of the area to be surveyed.

It will interface with any GPS receiver system that outputs NMEA 0183 or other data. Using NMEAPro ESL's NMEA DDE server it is able to log multiple channels from a variety of sensors and display the data in various formats to facilitate visualisation. Shown below is an actual real-time magnetic survey plot with a data trend view. Up to four views with different display characteristics and data can be opened simultaneously.

Technical Specification

• Routes: Unlimited. Max waypoints in a Route: 40. Auto WP change and reversed routes. Optional audio WP arrival announcements and vocal steering instructions for ease of following survey track lines.
• Tidal Atlas files: Unlimited. Max Tidal data points in a Tidal Atlas file: 100 x 13 (i.e 100 x -6hr HW +6hr).
• Internal "Quick" Log files: Unlimited, Max Fixes in a "Quick" log file: 98 with intelligent overwrite feature.
• Text Log files: Unlimited, Max Fixes in a Text Log file: Unlimited. Log format: User programmable with the parser.
• Interfaces: NMEA 0183. Using the NMEAPro server, Portable Navigator can log and display up to 10 auxiliary channels from up to 5 standard or proprietary NMEA sentences. NMEA output: Portable Navigator can output NMEA or proprietary sentences in almost any format to enable you to control an auto pilot, poll external equipment or contribute data to other "listeners" in integrated navigation systems.

Portable Navigator supports multiple chart views, each with individually configurable content and display characteristics. There is also a data trend plot for the main window to enable the selected data channel to be visualised as it is being collected or off-line for analysis. The data is logged to simple comma delimited text files, the format of which is specified by the user. This makes the exporting of data to other applications very easy. Portable Navigator provides full file compatibility with it's earlier DOS versions.

Use Data Zoom to quickly find the location on the sea bed of interesting data anomalies. Automatically insert event fixes with remarks, data trend plots and screen shots directly into an MS Word document file in real time, pre-preparing the survey report while still surveying.

Recommended minimum hardware : 600 Mhz Pentium PC, 128 Mb RAM, 40 Mb Disk space, COM port, USB or parallel port for Hardware Key. If your notebook only has USB ports use a USB to COM port converter cable..
