Aqua-Mètre R3000

AQUA-METRE R3000-NG   (ROV operated, down to 3000 metres):

The AQUA-METRE R3000-NG, like the R300-NG version, is a local underwater positioning system based on an acoustical interferometric scheme (mainly known as Ultra Short Base Line or USBL). It is particularly well suited to Metrology Class local 3D locating within the range of up to 250 metres from the reference point (the Base).

The system may be ROV operated and managed from the surface using acoustical networking features. The AQUA-METRE R3000-NG has been designed for deep offshore metrology (down to 3000 metres), the system is operated through a set of commands (monitor commands and acoustic commands) and may be operated using the AQUA-CAD software from PLSM that allows real time interface to BricsCad range of CAD tools.

The AQUA-METRE R3000-NG share the same elctrical and mechanical interfaces with the R300-NG version. The housing are made of special aluminum to cope with the deep operation, the interferometric frame has been qualified to withstand up to 350 bars (>5000psi). The R3000-NG Pointer is about the same size than the Base unit, it includes a large battery pack in order to keep in sleeping mode several weeks before operation if needed.
