The Gemini 620pd benefits from the latest technological advances in signal processing. These allow the 620pd to produce high performance bathymetry data, which can be output to industry recognized survey packages for processing. Designed for Remotely Operated Vehicle (ROV) mounting, the Gemini 620pd is manufactured in titanium and rated to an operational depth of 4000m.

Operating at 620kHz the Gemini 620pd is able to provide 10mm range resolution results with an angular resolution of 1° over a maximum swathe of 130°. The Gemini 620pd is able to deal with more varied environments, while continuing to provide high accuracy performance.

The Gemini 620pd software has been designed to provide the user with the ability to easily and effectively optimise the performance of the system. Automatic bottom tracking, variable gate setting, gate tilting as well as roll compensation are some of the automated features that ensure a survey can be completed, with minimal user interaction during operation.

Users can choose from a selection of beam patterns, allowing the 620pd to be used in a wide variety of survey applications. A Gemini Hub enables the user to connect up to 2 Gemini 620pd heads. The Gemini Hub is connected to a PC or laptop and ensures data from other survey systems (i.e. GPS, Gyro, MRU and SVS) are accurately synchronised.
