VEMO+ : real time
supervision software for subsea vehicle navigation
The VEMO+ software's main functions are the preparation, real
time monitoring, archiving and operational examination of
Ifremer's subsea vehicle navigation.
VEMO+ provides vehicle operators with a high-performance, easy-to-use tool
which works on all vehicles, to manage the navigation before, during
and after the dive.
VEMO+ meets the operational requirements in the fields of assignment
preparation, real time subsea trajectory plotting, supervising the behaviour of
the system and the support ship during the dive as well as the operational use
of the navigational data.
Functions
Before the dive
- creating and modifying cruise
parameters
- preparing and configuring dive
parameters :
- cartography
- navigation
- vehicle equipment
- data acquisition (network frames,
serial link)
- comments, etc.
During the dive
- Shared MMI combining control
and supervision features for the navigation and for the vehicle's equipment
(sensors, actuators, video, cables, alarms, etc.)
- undersea trajectory plotting :
- real time monitoring of
georeferenced trajectories for the support ship and the subsea mobiles
- bathymetry of the zone (isobath
curves)
- grid, grid referencing, axes and
scale indication
- display options (cartouche,
comments, hours on route, appearance of mobiles, drafting tool, etc.)
- interactive and ergonomic view
handling (scroll, zoom, centring on mouse-click or mobile, automatic
centring on mobile, printing, etc.)
- Various information (characteristics
of a route-point, azimuth/distance between 2 points, etc.)
- navigational aids :
- profile management (routes to
follow)
- guidance information (on profile,
target, characteristic point, mouse-click or mobile)
- vertical plane display
- various computations (distance
covered, speed, cartographic conversions, etc.)
- creating, managing and displaying events
(sampling, photos, etc.) and of georeferenced characteristic points (start/end
of dive, beacon, active site, basket, echo sounder, etc.)
- visualization as curves of captured
data or of positioning data over time or other data
- selective data archiving
- outward dissemination of data
(network, file, serial link)
- creating reports at the end of
the dive
- module
3D optional
After the dive
- technical examination
- archives management (back-up,
restoration, etc.)
- exporting the data
Technical specifications
- object-oriented software
- tools: C++, X11/Motif, Unix
