DT100 Multibeam Profiling Sonar & DT100 SIR
240 kHz multibeam profiling sonar with a Sensor Interface Relay box that connects and time-stamps sonar, GNSS, MRU, heading and sound velocity sensors.
Description
The DT100 is a 240 kHz multibeam profiling sonar with a 120° swath, housed in 316 stainless steel or Delrin. The companion DT100 Sensor Interface Relay (SIR) is a central connection point for bathymetric sensors: one or two sonars, GNSS/GPS, motion reference unit, gyro/heading and sound velocity. Powered by AC or DC, the SIR supplies DC operating voltage to each sensor and time-stamps sensor messages at their native update rates with 100 microsecond accuracy; a buffered GNSS output connects directly to a HYPACK acquisition PC.
