Survey Notes Which HYPACK Drivers to Use with the CEESCOPE and CEE ECHO

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
