ZIMA-R beacon responder

Zima-R is a beacon-responder of ultrashort baseline navigation system. The device is designed for receiving telecontrol commands from the base station, transmitting the telemetry information to the base station and for determining the direction of both the beacon (for the base station) and the base station (for the beacon) and the simultaneous distance determination.

The device can be both stand-alone (with an additional battery pack), and be interfaced energetically and informationally with the vehicle. In this case, telecontrol commands, distance to the base station and an azimuth angle to the base station can be transmitted to the vehicle.

An ideal solution for determining the direction and distance to underwater objects. The extremely small size, low power consumption and ease of use make the Zima direction finding system an ideal solution for working with autonomous and remote-controlled devices as well as determining the relative position of divers.
