Applications
The NaviPac
software is an integrated navigation software specifically suited for
applications like:
- General navigation
- Hydrographic & oceanographic surveying
- Geophysical 2D seismic surveys
- Port & harbour surveys
- Pipeline lay-barge management and control
- Pipeline pre- and post-surveys
- Barge/tug management
- Rig move management & control
- Cable installation & support
- Civil/offshore engineering work
- Underwater operations
- ROV surveys |

Modularity
NaviPac provides
complete modularity through use of the multi tasking, multi threading and
networking capabilities of the Windows 2000 and Windows XP/XPP operating system.
The software is highly flexible and user configurable, and the user interface
adhere to The Microsoft Interface Guidelines making it very intuitive and easy
to operate. |
Navigation Set-up
The NaviPac
set-up module provides easy selection of geodetic parameters, navigation
systems, devices, offsets and port settings. |
Device I/O Drivers
A vast number of
field-tested device I/O drivers are provided for most available positioning
systems, GPS/DGPS receivers, gyros, motion/attitude sensors, tide-gauges,
singlebeam echosounders, magnetometers, dynamic positioning systems, autopilots,
etc. Generic I/O drivers allow definition or customisation of own device I/O
drivers. Data is interfaced via RS232, a LAN or via a digital I/O interface.
Device I/O drivers for multibeam echosounders, multibeam side scan
backscattering, pipe- trackers, scanning and profiling sonars, etc. are provided
in the NaviScan software. |
Time Synchronization
Time stamping of
sensor data, incoming as well as outgoing, can be done in two ways, either by
the internal computer clock or by the PPS output available from most GPS
receivers. Using the PPS output data are synchronized relative to the GPS/UTC
time frame, resulting in an accuracy of a few milliseconds. |
|
Survey Planning
NaviPac allows for
survey planning through quickly creation of planned survey area and survey
lines. A variety of methods for creation of survey lines is provided, e.g. by
click-and-drag (of mouse/trackball), input of survey line coordinates, offset
(parallel) survey lines, cross lines, circles, arcs etc. Survey lines can easily
be adapted to fit a defined survey area. Creation of templates allows input of
other data formats.
Navigation Display
The Navigation Display graphically presents the
real-time absolute and relative positions of selected survey objects and
cartographic features. |
Helmsman Display
The Helmsman
Display provides off-track and along-track information, planned and actual fix
locations, in a fully configurable graphic format.
Electronic Charts
Vessel positions, survey lines (on DXF, DWG and ASCII formats) and objects may
be displayed superimposed on C-Map or S57 based electronic chart displays.
Coverage of depth information from singlebeam and/or multibeam echosounder as
well as DTM’s generated on-the-fly can be presented on the Navigation
Display through interface with the NaviScan software. |

Data Handling
NaviPac provides a
systemised way of managing and storing survey data. Records are saved to a
project directory allowing you to set up new surveys or to quickly switch to an
existing survey. During data logging records can be limited in time or file size
defined by the user.
Client/server System
NaviPac builds on a
client/server solution, which allows execution of all software modules
(including a/o Helmsman display, LogData and DataMonitor) on any Personal
Computer on the network. |
Windows Displays
Full system
flexibility allows you to design and configure your survey and preferred display
settings and layout to best fit your needs. You can open as many displays as you
want to, one of each type or several of the same type, and freely distribute
these to monitors working as slaves or to intelligent workstations for
individual windows set-up and interactive use.
Optional Modules
Optional software modules are available for NaviPac
comprising a/o:
· Sonardyne LBL positioning
· Barge/tug management system
· Cable and flexible pipe lay |
|
NaviPac Lite
NaviPac Lite
provides an affordable entry-level software package for on-line navigation.
NaviPac Lite features same functionality as the NaviPac full version, except
that the Lite version is limited in the numbers of device I/O drivers. This is
why it is suitable for minor surveys with few fixed sensors. Additional device
I/O drivers can be added to allow interface of other sensors. Thus a gradual
update to a partial or full version of the NaviPac software can be made at any
time. |
