AIS has landed! For our guide to AIS, click here. All vessels over 300 tons and all passenger vessels are obliged to carry an AIS transponder. The Nasa AIS engine receives these transmissions an converts them to NMEA format for use with PC chart plotting programs and dedicated chartplotters. The unit is supplied with a 12 volt power cable and a 9 pin serial computer cable. For convenience the engine can also recive NMEA information from a GPS receiver (at 4800 baud) which it then sends on to the display with the AIS data (at 38,400 baud). If your Laptop does not have a RS232 Serial port, a USB to Serial adaptor will be required. The AIS Engine requires NMEA input from a GPS and a marine VHF antenna (not supplied). The antenna can be either a dedicated antenna or the output from an antenna splitter such as the EasyAIS splitter. The AIS Engine is not watertight so it must be mounted in a position, which is dry at all times. As few display units will have a socket for both a GPS receiver and an AIS Engine, provision has been made in the Engine to relay the GPS position. SeaClear software is freeware and is given freely with the AIS Engine. It is a PC based chart plotter for Windows 2000/XP/NT/95/98/ME. With a GPS connected it displays the current position, speed, heading and other data on the screen. The chart is repositioned and new charts are loaded automatically as needed. Tracks may be saved to file for later reviewing and log book entries can be manually and automatically entered. Unlimited number of routes and waypoints can be created and used to assist the navigation. The screen area for charts is maximized with most functions accessed with the right mouse button. Zooming is provided with support for IntelliMouse wheel. SeaClear is created for nautical navigation but can probably be used for other navigation needs. Features
