PORTABLE HYDROGRAPHIC SURVEY SYSTEM

MODEL 620 PHSS

NEW

Originally designed to meet the demanding needs of the US ARMY, the Innerspace Technology Model 620 PHSS is a truly portable and fully integrated hydrographic survey system (PHSS) and is designed to collect hydrographic  X-Y-Z data from a small boat, Zodiac style craft or other marine vessel for the purpose of post-processing this data into bottom topographical maps primarily in near shore, littoral zone, inland waterways, lakes and reservoir operations.

 The 620 PHSS consists of a depth sounder (both analog and digital depth presentation), DGPS and data collection software. Via split screen presentation, real time sounding charts are displayed on one side of the 10.4 inch, daylight readable, color LCD and data collection software screens on the other side.  

The complete, self contained, data collection system is Windows XP based (both operating system and data logging) and is packaged in a waterproof, high impact , non-metallic transit/operating case and is designed for both commercial and military use.  The system is waterproof both open and closed.

 Having the depth sounder, data collection software and GPS in one, self-contained system minimizes external cabling to DC Power IN, GPS Antenna IN and Transducer IN. There are just three connections to make in the operating mode. Two other I/O connectors are for Keyboard IN and GPS Controller IN but both of these are for setup and are not used during data collection onboard the survey craft. 

The 620 PHSS is at the state-of-the-art as a small boat hydrographic data collection system.

MODEL 448 THERMAL DEPTH SOUNDER RECORDER:    

The 448 Thermal Depth Sounder Recorder provides survey precision, high resolution depth recordings using solid state thermal printing. The lightweight, portable unit is designed for use in small boat surveying as required for nautical chart production, engineering surveys, harbor and channel maintenance, pre and post dredge surveys, etc. The Model 448 TDSR uses a thermal printing technique pioneered by Innerspace for depth sounding which provides the high resolution and accuracy required by groups such as the U.S. Army Corps of Engineers, dredging companies, survey companies, port administrations, etc. The design allows easy integration into hydrographic data collection systems.

There are more 448’s in service in the USA than any other precision depth sounder. It is widely used by private survey companies, the National Oceanic and Atmospheric Administration and the U.S. Army Corps of Engineers. In the Corps of Engineers alone, there are over fifty 448’s in service at 18 district offices and a number of 449's as well.

In our opinion, and in the opinion of many of our customers, the 448 is the best precision sounder on the market in terms of performance and reliability. Many customer references are available and will be provided upon request; you owe it to yourself to get user comments before you purchase

MODEL 449 THERMAL DEPTH SOUNDER RECORDER:

The 449 Thermal Depth Sounder Recorder is a precision survey and scientific depth sounder with black and gray tone thermal printing. Chart recordings provide excellent detail where prevailing conditions include suspended sediments (fluff), light silt, mid water layering (thermal or biological) or aquatic vegetation. Unique Gray Threshold feature allows selective imaging of mid water replies. Single and dual frequency models are available.

The 449 is used for high speed (20 knots) condition surveys on ten boats in the lower Mississippi River by the New Orleans Corps of Engineers, where the hard bottom is digitized through a suspended sediment layer. The frequency used by the New Orleans Corps is 27kHz.

MODEL 449DF THERMAL DEPTH SOUNDER RECORDER :

The 449DF Thermal Depth Sounder Recorder is a precision, dual frequency survey depth sounder. The unit provides high resolution, dual frequency chart recordings and digitally displays both frequencies simultaneously. Maximum delineation between the two frequencies is obtained by printing one frequency in black and the other in gray. Typical frequencies are 200kHz and 24kHz or 210kHz and 33kHz. The 449DF is usually furnished with transducers, but existing customer owned transducers of any frequency can be used. Over-the-side or hull mount transducers are available.

MODEL 447 THERMAL DEPTH SOUNDER RECORDER:

The Model 447 is a precision navigation depth sounder for commercial and military ships. The 447 comes with remote depth alarm/depth display. The main cabinet has both thermally printed analog chart and digital display. Typically, digital depth would be displayed for the entire cruise, and the chart recording turned on when entering and leaving port for archival document purposes. Depth output is in NEMA format for use with integrated bridge navigation systems.

The 447 is currently installed on a number of Arco Marine oil tankers where they are providing flawless performance.

MODEL 445 AUTOTRACK:

The Model 445 Autotrack is a digital depth sounder/depth digitizer - stand alone operation or attachable to any analog depth sounder. The 445 is useful in very small boat applications and where no analog chart is required. The unit may be connected to data logging or computer equipment.

The 445A version provides deep water digitizing to 5,000 meters plus when used in conjunction with high power transceivers such as the 450C.

MODEL 450C TRANSCEIVER:

The 450C is currently being used by naval groups and an oil exploration company for deep water bathymetry.

SOUND VELOCITY PROFILERS:

The 443 Velocity Profiler was designed to provide the precise speed-of-sound needed to calibrate survey depth sounders for variations in sound velocity in the water column for US Army Corps of Engineers customers and others involved with precision waterways maintenance or dredging surveys.

Before the advent of the 443, a "bar check" procedure was used whereby a bar or plate was lowered a known distance and suspended under the transducer face. Then, if the sounder chart reading was slightly different, the speed-of-sound adjustment on the sounder was changed until the chart read the correct distance. However, the bar check is not always easy or safe to perform. It is especially difficult on larger boats, in winter where icy conditions exist on deck and where currents make it difficult to position the bar correctly.

The criteria for developing the Model 443 was that the product provide data that was as good or better than provided by the manual bar check. Innerspace has accomplished this; the 443 is easier to use and provides better data more consistently than the manual bar check procedure. The customers using the 443 on their daily surveys find it to be an indispensable survey tool.

Since the 443 provides precise speed-of-sound for each foot of the water column, this data can also be used to correct acoustical transmissions from any underwater ranging device, such as transponders used in oil exploration and other applications.
