MIDAS Echosounder GPS Echosounder

Echo Sounder 

Single (210kHz) or dual (210 / 33kHz) channel input, using unique “fuzzy logic” DSP to give accurate readings and reliable performance, even in shallow water. Data may be logged and output either raw (as measured) or corrected for tide and heave. 

Range: 0.3 - 100m (210kHz), 1.8 - 100m (33kHz) 

Accuracy: greater of ±0.01m or ±0.02% 

Resolution: 0.01m (210kHz), 0.04m (33kHz) 

Sample Rate: 6Hz 

Position 

MIDAS Surveyor logs and displays DGPS position data in WGS84 or Local Grid. User has full control over spheroid and projection constants for Local Grid setup. 

Standard: Integral 12 channel GPS/SBAS receiver with combined antenna: 

± 4m (CEP), with no correction 

± 2m (CEP), with SBAS correction 

Option : Surveyor also accepts user’s own differential, GPS or RTK data input. 

Other Inputs 

The Surveyor will accept data input from all the additional sensors listed below. All data may be logged and output in real time on a single RS232 channel, and tide & heave data may be used to provide real time corrections to depth data. 

Tide: RS232 text data from tide gauge or RTK. 

Heave: RS232 data from heave sensor (up to 60Hz). 

Sound Speed: Continuous or spot readings from Valeport Sound Velocity Sensors may also be logged. 

Gyro/Auxiliary: RS232 input of vessel heading or any other text string may be logged with the survey data. 

Event Marker: Surveyor is supplied with remote event marker 

Data Outputs 

Real Time RS232 output on a single channel of any, some or all of the active data inputs, in choice of industry standard formats. 

Memory 

16Mb internal FLASH memory provides nominal 32 hours of data logging. An optional 32Mbyte memory is available at time of order. 

Data Display 

240 x 128 pixel graphics LCD display, providing numerical and graphical depth display, position data (WGS84 or Local Grid) and all other incoming parameters. On screen help and simple menu-driven setup functions allow full system control. 

Electrical 

Internal: 8.4Ah sealed lead acid battery pack 

External: 12 – 24vDC 

Power: 3W (sampling), 25W (max when recharging) 

Battery Life: Nominal 24hours working time 

(Recharge using external power) 

Connector: Fischer 

Software 

Surveyor is supplied with SurveyLog windows based software, allowing data extraction & display. All data is presented in ASCII format, and may easily be exported for use in industry standard hydrographic survey software packages, or simple XYZ format data. 

Physical 

Surveyor: Rugged IP67 case, 35 x 33 x 16cm, 9kg 

Accessories: IP67 case, 41 x 33 x 18cm, 9kg
