We are pleased to present to you the series of underwater wireless digital communications modems  RedGTR, RedLINE and NATRIX that implement a transparent transmission channel. All the modems are performed in a single form factor with RedNODE navigation receivers and beacon-responders of LUNA and Zima systems using patented technology.

For tasks where a code link is required like telecontrol, transmission of a limited amount of telemetric information, we offer RedGTR code modems, that provide transmission of up to 64 code messages in the network to up to 20 subscribers and distance measuring functions.

Modems RedLINE and NATRIX provide the so-called transparent transmission channel with speeds of 80 bps at a distance of up to 8 km (RedLINE) and 560/1200 bps at a distance of up to 2500 m (NATRIX). Our modems are the smallest in the world and the most profitable in terms of price/reliability and transmission speed/dimensions.
