Boat Parameter Measurement

The Boat Parameter Measurement is a device to real time record parameters of the boat. This instrument contains sensor like GPS, IMU, and Load Cell. The data that recorded by sensors will be displaying at Boat Parameter Measurement software Graphic User Interface (GUI).

The Boat Parameter Measurement communicates with your PC using the USB (Universal Serial Bus) port. Boat Parameter Measurement works with either a USB 1.0 or USB 2.0 port and as such a driver is required for proper operation and communication.
