Depth Sounder Specs
The new generation of Bathymetric Survey Systems is the SURVEYCASE. This complete survey system includes a DGPS receiver and SDI’s Intelligent Depth Sounder (IDS) integrated with a rugged computer in a single small portable case.
SURVEYCASE operates from 12 vdc and includes an internal beacon receiver, a WAAS receiver or an internal radio for use with SDI’s Remote Differential Base Station. This small, low power, all-in-one package includes a daylight screen, waterproof keyboard and waterproof joystick. With the SURVEYCASE, navigation software, a battery and a boat you are ready to survey. SDIDEPTH and DEPTHPIC software provide replay and edit of data. HYPACK MAX or SmartSurvey provides navigation. SDI’s proprietary display is daylight visible and also dims for excellent night viewing.
IDS is a full survey grade depth sounder that digitizes the echo to 16 bit resolution and stores the full digital record on hard disk. IDS provides data play back with high resolution and detail. 65,536 shades of gray are digitized versus a maximum of 16 shades of gray typical of paper records. The depth resolution is maintained regardless of the depth range. DEPTHPIC and SDIDEPTH software provides convenient replay and reprocessing of hydrographic data without hand digitizing or scaling of position. Navigation data and all other collection parameters are saved with all depth soundings. Positions, events and operator annotations are exchanged between HYPACK and SDIDEPTH programs.
SDI’s hardened computers include internal shock mounted electronics, armored display windows, marine grade aluminum display housings and non-corrosive impact resistant cases, and stainless hardware. Display controls and hinges are o-ring sealed and connectors are waterproof or splash resistant.
This computer can be upgraded in the future unlike most laptops.
The SURVEYCASE uses 12 channel DGPS receivers with sub-meter accuracy and options for RTK cm accuracy. WAAS, USGS beacon receivers, and 10+ mile range radios for use with SDI’s reference DGPS base stations are available. HYPACK MAX Software by HYPACK, Inc. is available from SDI.
