NATRIX underwater digital acoustic modem

NATRIX are the series of wireless underwater digital communications modems that implement a transparent transmission channel.

NATRIX modems have an unsurpassed correlation of such parameters as power consumption, dimensions, speed and transmission distance.

One-piece housing unified with RedNODE devices allows you to use standard solutions for integration. Small size, low power consumption and ease of use make NATRIX ideal solution both for small ROV/ AUV and larger devices. Subscribers code division feature allows solving efficiently the data transfer tasks for several devices.
