GCS900 Grade Control System by Caterpillar Trimble Control Technologies


ITEM MODEL: GCS900 Trimble Machine Grade Control System

CONDITION: This system was previously used by a large construction company. This item is in working condition.

DESCRIPTION: The Trimble GCS900 with Dual GPS is a full 3D Control System that puts the site plan – design surfaces, grades and alignments – inside the cab. The dual antenna configuration is unique to Trimble GPS-based Grade Control Systems. Using GPS, the exact position, very accurate cross slope, and heading of the blade is measured. This is especially advantageous for complex design surfaces such as super-elevation grading tasks. GPS-based Grade Control Systems are ideal for larger site projects and long-term, multi-phase projects. The Trimble MS992 GNSS Smart Antenna is “smart” because it contains an integrated GNSS receiver, antenna, and isolation system in a single, ruggedized housing that can withstand even the toughest construction site environments. It is also the only commercially available GNSS antenna that offers the performance enhancements of a new Trimble RTK engine and supports the newest GNSS signals.
