Trimble MS990 Smart Antenna GPS
The Trimble® MS990 Smart Antenna is now available. A
rugged and reliable new GPS-based positioning sensor,
the MS990 is designed to provide advanced positioning
capability with Trimble GCS900 3D Grade Control
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.
The Trimble MS990 still optimally supports current GPS satellites and
- An advanced RTK engine providing faster initialization times when
satellite lock is lost and
better receiver performance when working in where obstructions exist.
- Tracking of GPS modernized L2C and the planned L5 signals to
increase the performance of the
system at longer baselines.
- Support for additional satellite constellations, such as GLONASS
that can increase system
utilization during periods of reduced GPS satellite visibility.
- Utilizes a standard, easy to use and remove mounting bracket with
quick release adjustment
which enables the MS990 to be quickly removed for daily storage for
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.
