3D GPS positioning system for excavators

ARVAexcavator is a GPS controlling system for excavators ideal in those situations in which is not possible staking or using laser.

ARVAExcavator displays the tridimensional position of the operating machine on the AUTOCAD sheet  project.

ARVAExcavator is composed of a rugged touch-screen provided PC using WinXP Embedded operative system on which is installed ARVAexcavator software integrated with a centimetric double-antenna GPS RTK receiver and with a set of angular sensors on the excavator’s jibs.
Once loaded the project on ARVAexcavator the software displays the tridimensional position of the excavator indicating to the operator the exact absolute position and height.
ARVAExcavator  offers the following advantages:

• 50% working productivity increase 
• Accurate excavation reference directly on board
• Workers’ safety guaranteed
• Essential for those situations in which is not possible staking or positioning lasers (sub-marines excavations, canals, dams construction, dumps etc….)

ARVAExcavator is being used in the building of the dams of the MOSE Project

High accuracy GPS controlling system for wired crane

ArvaGru is a GPS system available with different levels of precision (60cm EGNOS, 10 cm HP Omnistar, 2cm RTK) purpose made to operate in the most hostile environments, with dust, moisture and vibrations.
ArvaGru visualize instantly position and depth of the crane’s hook in respect of the project AVOIDING EVERY STAKING ACTION!
The software to set the positioning of boulders and stones is customizable and can load project files in AUTOCAD: DWG,DXF format.

The main advantages are:

• 50% work productivity increase
• Precise absolute position reference directly on board of the machine
• Chance to set  the positioning points list in office and to load it on ARVApc
• User friendly software
• Workers’ safety guaranteed
• Essential for those situations in which is not possible staking.

The whole compact system is composed of:

• Rugged  ARVApc PC  with high-contrast 8,4” touch-screen and decimetric or centimetric integrated GPS. Level protection breakage and shock, IP 65.
• Second receiver GPS WAAS/EGNOS with directional function
• Windows XP embedded operative system customizable ArvaGru
• Optional depth sensor
• Wirings.

3D GPS positioning system for dredging ships 

ArvaShip is a positioning system dedicated to  dredging ships based on the presence of three GPS.
ArvaShip displays ship’s position referring to a project plan. A typical application is a dam construction at open sea.  One GPS has a double antenna and broadcasts ship’s steering. The second GPS, placed on ship’s  crane, displays the crane’s hook real time height and position on the project plan. A third GPS, also mounted on the crane, gives its direction.

This advanced solution gives the captain the possibility to know  the real time certain positioning and steering of the ship affording him to work in  sync with the wired-crane.

Ship dedicated software shows at the same time its positioning in the sea in referring to the project plan and the position of the crane’s hook respect of the ship; it’s customizable and it permits to load project files in AUTOCAD: DWG,DXF. Also wired-crane dedicated software gives its positioning referring the project plan and is also customizable.

Main advantages are:

• Significant increase of work productivity even operating with no reference: open sea constructing site.  
• Precise reference of the absolute positioning on board of the ship and of the crane at the same time.
• Chance to plan the operations in office and to load on the ARVAPC the positioning points list.
• User friendly software.
• Operators safety guaranteed.
• Essential in all that conditions in which is not possible staking and using laser.

• Two industrial ARVApc with touch screen 8,4", high brightness display, integrated GPS receiver HP Omnistar (10 cm), or RTK (2 cm). Level of protection: shock and breakage, IP 65
• Third GPS receiver WAAS/EGNOS with crane directional function
• Operative System Windows XP Embedded with customizable software ArvaShip
• GPS with double antenna for ship direction
• Communication system with radio modem between the two ArvaPC
• Optional Depth Sensor
• Wirings.
