Trimble GCS900 Grade Control System

Trimble GCS900 Grade Control System: 3D Automatic Control
One of the most revolutionary changes in the way earthworks are performed has been the introduction of 3D systems originally by Trimble in 1995. The Trimble GCS900 Grade Control System represents the next-generation 3D system from the company that invented 3D grade control.

The GCS900 Grade Control System is a cutting-edge earthmoving grade control system that puts design surfaces, grades and alignments inside the cab. The system uses GPS, GPS and laser, or advanced total station technology to accurately position the blade or bucket in real time, significantly reducing material overages and dramatically improving the contractor’s productivity and profitability.

The Trimble GCS900 is extremely flexible and can be used on excavators, dozers, motor graders and scrapers. You may purchase the GSC900 outright or as an upgrade from a Trimble GCS300 through GCS600 Grade Control System. And with its CAN-based design, the GCS900 can be easily moved from machine to machine, as needed.


Trimble GCS900 Features: How Does it Do That?

The positioning sensors are used to compute exact position of the blade or bucket many times per second. The on-board computer uses this position information, and compares it to the design elevation to compute cut or fill to grade. This information displays on the SV170 screen— in plan, profile, cross-section view, or text. The cut/fill data is also used to drive the valves for automatic blade control.
Additionally, the cut/fill data is passed to the GCS900 lightbars, providing additional visual guidance to the operator for up/down to grade and right/left to a defined alignment. The light bars are separate from the display so that the operator can focus on safely operating the machine by having the light bar in the field of view.

The MS980 GPS Smart Antenna, the SR300 laser receiver and the ATS Construction Total Station all connect to the same cable harness. This allows the contractor to easily switch between sensors; the contractor has the flexibility to use their system for all phases of earthmoving---from mass excavation through to finished grading.



Trimble MS990 Smart Antenna

A rugged and reliable new GPS-based positioning sensor, the MS990 is designed to provide advanced positioning capability with Trimble GCS900 3D Grade Control Systems.

The MS990 is the only commercially available integrated GPS smart antenna that offers the performance enhancements of a new Trimble RTK engine and supports the newest GPS signals.

Each unit contains a GPS receiver, antenna, and isolation system all in a single housing. It is designed specifically for installation on the blade or cab for use with GCS900 3D Grade Control Systems.

The MS990 uses an advanced RTK engine to provide faster system initialization times when satellite lock is lost. It also allows the GCS900 Grade Control System to increase machine productivity and utilization in tough areas of the jobsite, where tree canopies or other obstructions may exist.

The MS990 supports the L2C and planned L5 modernized GPS signals, improving performance of the GCS900 Grade Control System in job site areas where dense tree cover exists. The MS990 can also utilize signals from additional satellite constellations such as GLONASS. When combined with signals from GPS, this reduces system downtime when satellite availability is obstructed, such as when working against high walls or in deep cuts.



Trimble CB430 Control Box

The CB430 Control box is a computer that runs the system software. The control box has a color LCD screen to display guidance and other information, and push button controls to operate the system. In addition, the control box has a data card slot for loading and saving machine and display configuration data, and for loading and saving designs.
