Trimble SPS985 GPS GLONASS Base Or Rover Antenna


Trimble SPS985 Smart Antenna

Rugged, Reliable Positioning
The ultra-rugged Trimble® SPS985 GNSS Smart
Antenna offers unmatched reliability for
construction site positioning. Ideal for use on small
and large job sites, the SPS985 can serve as a GNSS
rover system or as a Wi-Fi enabled base station for
other GNSS operations including machine control.

Easy-to-Use Rover
The SPS985 is engineered to stand up to the
most dynamic and rugged jobsite measurement
applications. The integrated smart antenna
design and quick release connector make it easy
to transport and set up on a range pole, ATV or
supervisor truck.

The SPS985 can move from one site measurement
application to another with one quick release,
saving set up time and maximizing use time. For
example, a grade checker can mount the SPS985 to
an all terrain vehicle and conduct site topos, check
as-builts, and road center lines in even the roughest
site conditions. The SPS985 can withstand the high
vibration scenarios often seen on ATV-mounted site
work without interruption or fear of damage.

With Trimble SCS900 Site Controller Software,
you can:

  • Determine cut/fill on a range pole, utility vehicle,
    or truck
  • Stake out site or road features, utilities, daylight
    lines and side slopes
  • Measure progress and calculate material
    stockpile volumes
  • Carry out as–built measurements, grade checks
    and laid material thickness checks

The SPS985 integrates numerous timesaving
features in a compact and rugged system. It has
never been so quick and easy to get measuring.
Initial site work and topo can even be done
base station free using satellite delivered GNSS
corrections to the rover.

The Trimble Web UI™ eliminates the need to
travel to the job site for routine monitoring of the
established base station. Now you can assess the
health and status of the base station and perform
remote configurations from the office. Setting a
new standard for rugged reliability, the SPS985
GNSS Smart Antenna keeps your crews working,
not wasting time with GNSS maintenance.

Reliable Base Station
The SPS985 can also serve as a powerful site base
station, using integrated Wi-Fi or optional radio to
send and receive corrections for rover or machine
control work. It is the easiest base station on the
market – just put it on the tripod, switch it on, and
you’re ready to go. The SPS985 will automatically
establish a Wi-Fi connection with the machine radio
or GNSS rover and begin transmitting corrections.

With integrated Trimble 360™ receiver technology,
the SPS985 GNSS Smart Antenna can “see” more
GNSS constellations and signals than traditional
GPS, so you can expect greater accuracy in more
challenging conditions such as under tree canopy
and in urban areas. That also means more uptime
using the system and more productivity for your
job crews.
