DREDGEPACK ®
III. Installation Instructions
A. GNSS Receiver
DREDGEPACK® requires dredge position and dredge heading. The best method to obtain this data is to use a dual
antenna GNSS receiver.
- Dredge position: The main antenna can be used for calculating the position and elevation of the dredge. For better
performance, the GNSS receiver can be upgraded to have a low uncertainty using RTK (Real Time Kinematic). For
the best performance, the receiver needs to be combined with a source of corrections (RTCM or CMR). The GNSS
receiver is provided with all of the accessories (i.e. antennas, cables and interfaces). We can also provide a radio modem
and RTK base station when requested.
- Dredge heading: We offer a GNSS receiver that can calculate the heading using the secondary antenna.
For better satellite coverage, we recommend installing the GNSS antennas on top of the cabin free of obstacles. To
avoid measuring complicated offsets, install the antennas parallel or perpendicular to the center axis of the dredge,
as shown in the following images. The antennas can be installed from aft to forward or port to starboard.
