Because of the unique time-stamped data output of the CEESCOPE™ and CEE ECHO™,
HYPACK software offers two driver configurations, with survey timing based either on “CEE time”
or “PC time”. In both cases the CEESCOPE driver is used for the sounding data however a special
version of the GPS-NMEA0183 driver is available to access the CEE timing benefits. It is
recommended that users select the special “CEE time” configuration in all cases except when
ancillary equipment with no time-stamped output such as a side scan sonar is used
simultaneously. It is important to use “CEE time” when recording telemetered data in HYPACK

In order to maintain exceptional data quality with telemetered data when using the CEE-USV™ unmanned survey boat, the CEESCOPE LITE™ echo sounder applies a precise time tag to all data recorded internally and output to the shore over the radio. The results of a field test using the latest HYPACK® driver are shown.

Despite there occasionally still being a requirement for paper records supporting single beam hydrographic surveys, we choose not to offer any echo sounders that have this feature. Besides focusing more on portable units where paper is of no value, here are our thoughts on why we believe the paper chart to be entirely unnecessary.

In addition to providing valuable water volume data for site water balance models and tailings storage facility (TSF) operations, using advanced echo sounder techniques may also provide insight into tailings deposition pattern and compaction processes. This paper as presented by Newfields LLC at the Tailings and Mine Waste 2016 conference in Keystone, CO, USA describes an unmanned survey vehicle approach to tailings dam bathymetry.
