Serious Disclaimer: NavMonPc is a work in progress, and almost certainly contains bugs, errors, and omissions. It may or may not be useful to you. I make no promises that it will not cause your computer to explode, but if it does, be assured that it was accidental and I am very sorry. However, I won't be sorry enough to pay for any damages: direct, incidental, or imaginary.

NavMonPc is a Windows program for the capture, display, and playback of NMEA-0183 data. The user interface is optimized to run on a low-power, small-format "netbook" style of computer, but it will operate on any Windows-compatible machine. It is not intended to replace a chartplotter -- NavMonPc does not display standard navigational charts -- but instead this program is designed to supplement your chartplotter and provides additional features and convenient access to important navsystem data. NavMonPc features include:

  • Dial display of critical parameters and conditions
  • AIS (Automatic Identification System) decoding and target display, including flexible proximity and approach alarms
  • Anchor-watch alarm
  • Depth Alarms
  • Course, Heading, Speed, Wind alarms
  • Man Overboard alarm
  • Strip-chart style displays of course and speed, windspeed and direction, water depth and temperature
  • Concise on-screen log display
  • Logging to file
  • Flexible filtering and routing of input data
  • Multiple RS-232 serial interfaces, and TCP/IP network interface
  • Multiple "Virtual serial port" outputs of bridged / routed data for use by other programs.

NavMonPc has been tested with the Windows-XP, Vista, and Windows 7 operating systems.
