testing tool by simulating the output of various nautical instruments
Edit By BS Editor: NemaTalker (NMEA Talker) provides the user and the developer of NMEA software and hardware with a very powerful development and testing tool by simulating the output of various nautical instruments, including GPS.

The program can be successfully used for educational purposes as well.

The program will transmit proper NMEA 0183 sentences via a PC serial communications port using the industry standard RS232 interfacing option. This data then can be processed by chart plotters and other devices without the need to leave the workshop or office. NemaTalker can also send the NMEA data over the TCP User Datagram Protocol (UDP) to a UDP client.

Although the name of the program suggests that it only can act as a talker, it is also capable to receive incoming data, so functioning as listener. Incoming data however is not processed, but the raw NMEA data can be stored in an optional log file and made visible in a convenient trace window, showing incoming and outgoing messages simultaneously.

Currently the program can simulate the output of 1 to 6 different instruments simultaneously: GPS, Weather, Sounder, Heading, Velocity and Radar, plus a feature for custom formatted sentences. The program is designed so that extra instruments can be added in a relative simple way. (Sailsoft will be happy to give you a proposal for the development of extra instruments or other functionality currently not provided in the current version.)

Dynamic parameters that are common to all instruments (Altitude, course and velocity) are collected in one panel at the right side of the window, called the cockpit. Common parameters that are more Static of nature can be set and altered in a separate window.

Large buttons are provided to open any of the 7 instruments. They can also be opened in the Instruments section of the main menu. you can free download NemaTalker 1.9.5 now.
