Instruments and targets
Simulate GPS, Weather, Heading, Radar, Sounder, Velocity, Transducer, Attitude, custom sentences, Bridge Alert Management and 5 AIS target types.
NMEA, AIS & Radar simulator
Professional NMEA, AIS and Radar simulation in one environment
NemaStudio is a Windows application for simulating valid NMEA 0183 and IEC 61162 output from nautical instruments, sensors and target objects.
- Run multiple nautical instrument and sensor simulations together with multiple AIS targets across 5 AIS target types.
- Produce custom formatted sentences alongside the built-in instruments and targets.
- Match multiple instruments, targets and ports over the same or different ports simultaneously.
- Transmit through configurable serial ports and Ethernet UDP multicast or monocast connections.
- Create realistic navigation sensor and traffic scenarios for ECDIS training and simulation.
Core capabilities
Built for practical marine testing workflows
Serial and Ethernet output
Send valid NMEA 0183 sentences through configurable PC serial ports and Ethernet UDP multicast or monocast connections.
Control center
Control dynamic parameters common to all objects—including altitude, course, velocity and rudder—from one panel.
Saved state
Optionally save the settings and current state of all objects on exit, then continue where you left off after restarting.
Inside the product
Match instruments, targets and ports to your test setup
All instruments, targets and communications ports can be matched and mixed. Multiple instances of several objects can transmit over the same port or over different ports simultaneously.

Testing configuration
Test NMEA and IEC 61162 equipment in your own environment
Generated data can be picked up and processed by navigation equipment supporting the NMEA/IEC 61162 protocol, reducing the need for field testing and physical instruments. This makes NemaStudio particularly suitable for ECDIS training and simulation.
- Use virtual instruments with configurable dynamic settings.
- Demonstrate products without installing and calibrating real NMEA instruments.
- Connect NMEA 2000 networks through a suitable gateway such as the Actisense NGX-1.
- The gateway translates generated NMEA 0183 sentences to valid NMEA 2000 PGNs.
Mix and match
Use multiple instances of instruments, sensors and targets over the same or different ports simultaneously.
Dynamic control
Common dynamic parameters are collected in the control center. More static parameters are configured under a separate tab.
Save current state
Optionally save all object settings and current state when exiting, then continue where you left off after restarting.
Flexible interface
Resize, hide and reposition panels, and use the embedded text editor to edit NMEA data without leaving NemaStudio.
