NMEA Simulator

NMEASimulator is an easy to use NMEA data sentence generator, ideal for quickly and simply producing a data stream for your connected NMEA devices.

Mimics Vessel movement, GPS fix information as well as environmental information such as Wind speed / direction and Water temperature / depth. It also provides the ability to generate waypoint information by "marking" the current position.

NMEASimulator generates NMEA sentences from seed data which you provide, applies a variance to mimic vessel movement, and then transmits these sentences via TCP/IP to connected devices.

Features:
 - Transmit messages over Serial, TCP or Web Socket (for use with browser clients)
 - Can operate in both TCP server (to accept client connections) or TCP client (sends data stream to a server) modes.  
 - Manual control of values and GPS fix status

User definable seed data includes:		
 - Vessel: starting position, speed & heading
 - Wind: speed & direction 
 - Water: temperature and depth

NMEASimulator provides visual representation of the generated data stream via a Dashboard to quickly and easily see the values being sent to connected devices.

NMEASimulator generates the following NMEA sentences:
  GPGGA: GPS Fix Data
  GPGSA: GPS DOP and active satellites
  GPGLL: Geographic Position
  GPRMC: Recommended Minimum Navigation Information
  AIMWV: Wind Speed and Angle
  AIMTW: Water Temperature
  SDDPT: Water Depth
  SDDBT: Water Depth
  SDDBK: Water Depth
  SDDBS: Water Depth
  GPWPL: Waypoint Location
  GPZDA: UTC Date and Time
 !AIVDO: Own Vessel's Information
 !AIVDM: Other Vessel's Information

NMEASimulator generates the following AIS Messages:
  Type 1: Vessel Position Report
  Type 4: Base Station Report
  Type 5: Static & Voyage Data
