Trimble GPS Package
The survey data is displayed on the operator’s screen and re-mapped in real time, based on the depth and location of the IMS SolidsMaster Cutterhead system. This allows the operator to maximize digging efficiency while providing a record of digging operations for their client(s).
The IMS GPS System tracks the following:
- Dredge Position
- Dredge Heading
- Dredge Cutterhead Depth
The operator must upload an XYZ file or pre-dredging survey into the GPS laptop. This will allow the system to do the following:
- Provide a history of dredging operations
- Shows “as surveyed”
- Shows “as dredged”
- Cut real time profiles at the digging tool position
- Update the “As Dredged” surface based on the depth of the digging tool
Real time sections in the IMS GPS program can be:
- Plan view
- Sectional views
The IMS Dredging GPS System is comprised of the following components:
- Trimble MPS865 Receiver
- Dual GA830 Antennas for dredge positioning and heading
- Trimble Marine Construction Software (TMC) activated with dongle
- Three LR970B Angle Sensors:
- One in cab for pitch/roll
- One mounted on ladder in submersible housing for ladder position
- One mounted on cutter-head shroud for cutter position
- 14” Panasonic Toughbook installed above right dash via mounting arm for data collection and display (removable for security purposes)
- Installation of equipment at IMS factory
- Field start-up and training services
- ***OPTIONAL UPGRADE – Subscription for CenterPoint RTX: Precise Point Positioning (PPP) technology delivered via satellite for < 10 cm accuracy – Recommended. Annual fee under $2,000. Client can purchase subscription directly from Trimble.
