Trimble MS992 GNSS Smart Antenna

Trimble MS992 GNSS Smart Antenna

The Trimble® MS992 GNSS Smart Antenna is "smart" because it contains an integrated GNSS receiver, antenna, an 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. All that means increased machine productivity and utilization in areas that were previously difficult to use GPS machine control - including under tree canopy and in urban canyons.

Designed for rugged operation on Trimble GCS900 Grade Control Systems and CCS900 Compaction Control Systems, the MS992 is available in single or dual configurations on the following machine types:

  • Dozers
  • Graders
  • Excavators
  • Scrapers
  • Pull-type Scrapers
  • Soil Compactors
  • Asphalt Compactors

Why Dual GNSS Antennas?

The patented dual MS992 antenna configuration is a unique advantage of the Trimble GCS900 Grade Control System. Using two GNSS antennas, the exact position of the bucket, blade or drum is calculated along with very accurate cross slope and heading. Dual GNSS configuration is especially advantageous for operations with dozers with angle blades, graders, and on complex design surfaces such as super elevations.

The MS992 GNSS Smart Antenna offers numerous features and benefits for earthworks and compaction contractors, including:

  • Single, rugged cab or blade mountable unit - powerful GNSS receiver, antenna, and isolation system in one unit
  • Support for the GNSS modernized L2C and the planned L5 signals
  • Advanced RTK engine means faster initialization times when satellite lock is lost and enhanced performance near obstructions
  • Advanced foliage detection when working near trees
  • Support for GLONASS
  • 3 LED indicators that provide instant operational feedback
  • On-machine I/O connection by single data cable connector
  • 100% sealed housing
  • An easy to use removable mounting bracket with quick release adjustment ratchet

These advances improve the contractor's ability to work in tougher environments, at longer ranges, and with faster initialization times. This results in increased productivity and reduced downtime on the construction job site.

How does GNSS work for construction?

Each on-machine GNSS receiver (MS992 or MS972) computes its exact position many times per second based on information it receives from GNSS satellites and a correction source. Simultaneously, an on-board computer or control box determines the exact position of the blade, bucket, or drum. It compares these positions to the design elevation and computes the amount of material to cut or fill to reach grade.

Cut/fill data is passed to the in-cab control box and lightbars that guide the operator to move the cutting edge up or down for grade and right or left of a defined alignment. The same data is also used to drive the valves for automatic blade control.
