Description

The COMPuting and Telemetering

Transponder (Compatt) is a

microcomputer controlled subsea

transponder used for acoustic

navigation and positioning. The EHF

system is suitable to a wide range of

tasks such as underwater

measurement, remote control and

monitoring.

Extra High Frequency (50-110 kHz)

version of Sonardyne’s fourth

generation family of transponders

sea installation and removal by

divers and ROVs making it an ideal

tool for use in spoolpiece

measurement applications.
