Teledyne PDS Multibeam Introduction

Teledyne PDS Multibeam is an acquisition, processing and modelling package built with your end product-deliverable in mind.

Widely used by companies around the globe on a broad range of hydrographic projects, PDS has a strong following among port and harbor authorities and dredging contractors. Its advanced functionality also adds real value for offshore operations in the energy sector by reducing processing time and eliminating laborious manual tasks.

PDS is developed to support Teledyne RESON’s market leading brand multibeam echo sounders from Acquisition to Charting, PDS also sup-ports third party brands ensuring commonality of software systems & processes across your fleet.

In addition to charting PDS is a powerful tool for construction modeling for which PDS has an outstanding reputation.

On the fly filtering including TPU filter

A single file structure ensures that all raw data is collected and accessible at each stage of the process and as PDS flags filtered data this means you can review the processed data and make changes at any stage or even undo processing steps quickly. As all data is synchronized, PDS allows you to identify, offset or latency errors that other software has difficulty identifying. By showing the different sensor data in a time-series. PDS supports QC tools such as 3D views, TPU profile, QC views and others to ensure that your data as collected is of the quality you expect. The real-time TPU value is calculated for each bin and can be viewed as colors or used as filter settings which can be applied real time during Multibeam data acquisition providing real time automated cleaning.

Data processing

The PDS 3D editing module combines MB and laser calibration (where applicable) with editing of 3D swath and sound velocity profile, DTM and CUBE modeling/editing and also water column visualization. Combining these in a single package will save you and your projects valuable time.

Quick clean

Quick clean of your MBES data uses the PDS DTM filter and beam filter where you generate a DTM then filter / edit the DTM and clean your point cloud using the beam filter with the DTM as reference. That way data sets are cleaned in minutes saving further valuable time.

While doing the final touch cleaning on your swath data, your CUBE and DTM models are updated on the fly and the processor immediately sees the results of his work. When more elaborate data processing is required then PDS files can be easily imported into the Teledyne Caris package without the need for conversion.

Automatic pipeline(s) detection

The pipeline/cable detection module in PDS may be used to automati-cally detect and track pipes and cables, display them in 3D and store the surveyed route  as xyz route file. Where  used with the Teledyne RESON SeaBat series of MBES PDS you further benefit from FlexMode which optimizes coverage over the flowline or cable. Where as-laid route is known this information may even be used by PDS to proactively steer the SeaBat’s FlexMode sector towards the product even where buried so that when the pipe/cable comes visible the tracking starts directly without operator intervention.


The chart module offers the operator quick plot results. Convenient templates ensure progress plots are generated in just minutes by simply by replacing the DTM with the latest version.   

Fast and accurate data production has never been so simple.
