Zima2-BK - Zima2 USBL direction finding antenna Device specification |
KEY FEATURES
- Extremely small size and weight
- Operating range up to 30001 m
- Reliable and noise-immune technology of digital broadband acoustic communication
- Subscribers code division - up to 16 responders
- Low power consumption (Rx/Tx) 0.5/10 W
- Patented monoblock design
- Built-in depth/temperature sensor
DESCRIPTION
Zima2-B - direction finding antenna of the ultra short baseline system Zima2 USBL. The device uses a fixed-length code division signal to provide heading, range, and depth of responders Zima2-RK.
When using an external GNSS receiver and Compass, the device allows you to determine the absolute coordinates of the responder beacons. Sequential operation of up to 16 responder beacons is provided.
The ideal solution for determining the direction and distance to ROV, AUV and divers.
Extremely small size, low power consumption and ease of use 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.
