Device specification

KEY FEATURES

DESCRIPTION

Zima2-R - responder of ultrashort baseline navigation system Zima2 USBL.

The device is designed to be placed on an underwater object in order to determine the location of this object in real time using a direction-finding antenna Zima2-B.

The device can be either autonomous (with an additional battery pack) or coupled energetically with the carrier.

Extremely small size, ease of use and low power consumption make the direction finding system Zima2 USBL an ideal solution for working with autonomous and remotely controlled vehicles, as well as determining the relative position of divers.
