Systems and Sensors
- Pressure: Paroscientific 8B7000-I, Digiquartz depth sensor, rated to 7,000e meters (23,000 feet)
- Doppler Velocity Logger (DVL): RDI, 300kHz
- Doppler Velocity Logger (DVL): Nortek, DVL500, 6,000 meters
- Attitude sensors (pitch, roll, heading-internal): IXBLUE PHINS III
- Inertial navigation (internal): IXBLUE PHINS III
- Multibeam mapping sonar: Kongsberg EM2040, 200Khz and 400Khz
- Edgetech 120/230/540kHz Side Scan
- Edgetech 4kHz to 20kHz = 4-24kHz chirp sub-bottom profiler
- Three high precision, digital, APS 3-axis fluxgate magnetometers; two mounted midship (port, starboard) in a horizontal gradient mode and a third mounted centrally within the vehicle above the other two in a vertical gradient mode.
Scientific Equipment Interfaces
|Digital:||RS232 standard ports available (300 through 115,200 Baud)|
|Power:||12, 24 and 48 VDC switched circuits available, custom voltages upon request|
|Data:||Instruments can be synced to precision clock (e.g. all the main computer stack, imaging stack, multibeam, sidescan, PHINS gyro are synced)|
** Potentially able to accommodate other digital/power formats and/or quantities.
All science gear connections must be worked out during the pre-cruise process.
