The heart of the system, the processor ESA INSTRUMENTS BOX

Esa Instruments Box is able to process al signals (included analogues ones) coming from the sensors, and makes them available to the users, with all dedicated settings, calibrations and damping desired

Thanks to its high computational frequency, the processor is the ideal choice the instrumentation governor, being the collector for the signal coming from the sensor.

Take Control of your data

Advanced Settings just one click away.

Thanks to the dedicated app Esa Instruments it is possible to control every aspect of the instrumentation in an easy and intuitive way. All advanced settings of sensors and data, like offset, damping, gain are easy to set and than are made available to every output device: chartplotters, displays, mobile devices.

Discover all the options available to precisely customize your data on board, like:

  • Correction Table of TWS e TWA
  • offset Wind Angle
  • offset Compass
  • boat speed gain at 2 levels
  • damping for each data

All data calibrated in this way are processed by esa Instruments box and sent back in the network: in nmea0183, nmea2000 and wi-fi.
