At the heart of HYPACK® is the SURVEY program. SURVEY allows users to perform an entire range of surveys, from simple GPS-Echosounder jobs to complex side scan and multibeam transducers mounted on ROVs. SURVEY can support single or multiple vessels. The multiple vessel support allows you to track the main vessel and an ROV or multiple vessels during naval exercises. SURVEY supports GPS, Range-Range, and Range-Azimuth positioning systems. It also can provide real time water level calculations using RTK GPS and a heave-pitch-roll sensor. It also provides interfaces for over 150 different sensors, including single beam echosounders, dual frequency echosounders, multiple transducer echosounders, multibeam sonars, gyros, heave-pitch-roll sensors, magnetometers, telemetry tide gauges, side scan sonars, flourometers, oxygen sensors, etc. The information for each sensor is time-tagged to within .001 second and logged to a file for post-processing. Meanwhile, the SURVEY program gives constant guidance to the helm with a left-right indicator and a graphic area map which can be displayed in either a "North Up", "Vessel Up" or "Planned Line Up" orientation.

Background Files The background display in SURVEY’s Area Map can display electronic chart data from ARCS, S-57, C-Map, NIMA Vector Product format, or BSB Raster charts. It can also display engineering drawings from Microstation DGN or in CAD DXF. SURVEY can also display your vessel over an orthometric TIF file, allowing you to use aerial photos for your background display. SURVEY allows you to combine different background file formats. For example, you can place a construction drawing in Microstation DGN format on top of your S-57 electronic chart file.

Targeting SURVEY allows users to display target locations. Target locations can be marked in real time or prepared in advance and then used to navigate to user defined locations for water quality samples or recovery of bottom mounted equipment. They can also be used to mark aids/hazards to navigation, such as buoys, wrecks, rocks, etc.

Color-Coded Depth Matrix SURVEY allows you to "paint" the bottom with single beam, multiple transducer or multibeam depth information. This feature provides you with a real time and permanent bottom coverage map which can also be used to locate bottom features and depth outliers. Depth matrices can be plotted in HYPLOT or can be exported to ASCII XYZ files for import into other applications.

Boat Shapes In certain applications, it’s nice to see the exact outline of your survey boat, barge, dredge, etc. HYPACK® has a simple BOAT SHAPE EDITOR program which allows you to describe the exact dimensions of your vessel.

Anchor Handling Routines HYPACK® allows users to place, drop and retrieve up to nine anchors on each vessel. This can be handy when working with four-point mooring systems or when performing construction on pipelines.

Night Operations HYPACK®’s SURVEY program allows users to toggle between Day and Night colors, allowing for 24-hour survey operations.

Real Time Water Levels from RTK GPS
HYPACK, Inc., working with the U.S. Army Corps of Engineers, was the first to be able to offer the capability of determining real time water levels using RTK GPS.

The SURVEY program can translate the precise height above ellipsoid available from RTK to a height above chart datum. Using the heave-pitch-roll information, and the offsets between the GPS antenna and the echosounder transducer, we can then determine how high the transducer is relative to the chart datum.

The rest is simple! Several USACE survey groups and private surveyors are now eliminating the need to maintain expensive tide gauge networks.

Calibration Routines HYPACK® contains tested routines to calibrate delay times between your GPS and echosounder and our famous PATCH TEST program for the calibration of multibeam systems.

HYPACK® is used by over 2,000 surveyors around the world. The SURVEY program can be found on everything from a small notebook computers in a dinghy operator’s lap to a large rack-mounted system on an oceanographic ship.

HYPACK® is the result of over 10 years experience in running hydrographic survey programs in DOS, Windows™ operating systems from 3.11 to XP. While others are just beginning, HYPACK, Inc. has been fine-tuning features and adding functionality to remain on the cutting dge with new technologies.
