GNSS observables and the navigation functions in the GNSS receiver are not used.
With loosely coupled
inertial/GNSS integration, the GNSS position and velocity solution are processed to aid the inertial
navigator.
POS MV employs tightly coupled integration to enhance performance, especially rapid Real-Time
Kinematic (RTK) recovery after a loss of GNSS signal reception. Depending on the availability and
relative quality of sensor inputs such as the primary GNSS, auxiliary GNSS and base station GNSS
corrections, POS MV will automatically switch between tightly coupled and loosely coupled algorithms to
ensure maximum performance.
With its use of leading-edge technology, POS MV marks a significant breakthrough in the field of aided
inertial navigation and precision motion measurement for use in marine applications. The accuracy and
stability of measurements delivered by the system remain unaffected by vessel turns, changes of speed,
wave-induced motion, or other dynamic manoeuvres.
Therefore, by using POS MV, you can continue survey operations during poor weather and throughout
deteriorating sea conditions. This allows a more efficient use of survey time and a reduction in the overall
cost of the operation.
POS MV generates attitude data in three axis. Measurements of roll, pitch and heading are all accurate to
±0.02° (±0.03° for WaveMaster) or better, regardless of the vessel latitude. Heave measurements
supplied by POS MV maintain an accuracy of 5% of the measured vertical displacement or ±5 cm
(whichever is the larger) for movements that have a period of up to 20 seconds.
The system includes a compact disk containing the MV-POSView Controller program, which runs on a PC
under Microsoft Windows
®
. After you install the POS MV, you can use this program to configure the
system and monitor its status during operation.
After you have configured the POS MV successfully, you can operate the system in two start-up modes:
•
You can use the controller program to enable navigation mode and to monitor the status and
performance of the system,
or
•
You can operate the POS MV in stand-alone mode. In this mode, after power-on, the system will
enable navigation mode and deliver measurements automatically through whichever ports you
have selected.
Communication between POS MV and the controller program is through a 10/100BaseT Ethernet link:
•
Data output by POS MV may use the Universal Datagram Protocol (UDP) so that other
computers attached to the same Ethernet Local Area Network (LAN) can receive the data or
Transmission Control Protocol (TCP) so that only a single computer can receive the data.
