Dynamic Positioning Transponder 6

Sonardyne International

Yateley, GB

Description

Our Dynamic Positioning Transponder 6 is designed to be used as a seabed reference transponder by USBL acoustic positioning systems, installed on many Dynamically Positioned (DP) vessels. The Dynamic Positioning Transponder 6 (DPT 6) supports Sonardyne’s latest Wideband®2 acoustic ranging and telemetry providing high accuracy positioning, robust performance in noisy and multipath conditions and easy set-up and use. With hundreds of channels, less interference to and from other acoustic systems and multi-user capability, Wideband®2 enables easier SIMOPS vessel capability. These features of the DPT 6 help de-risk subsea operations and save vessel time and cost.
