Introduction
The SPS985 GNSS smart antenna can be used for the following infrastructure and site development
applications:
l
Layout of structure foundations, caissons, and piles
l
Earthworks, fine grading and finishing stakeout operations
l
Initial site measurements to verify design levels and regular subsequent measurements to
determine progress volumes
l
Vehicular-mounted site supervisor applications
l
Measurements and grade/thickness checks on laid materials
The GNSS smart antenna incorporates a GNSS antenna, receiver, internal radio, and battery in a
rugged light-weight unit that is ideally suited as an all-on-the-pole RTK rover or quick setup/rapid
mobilization base station. LEDs enable you to monitor satellite tracking, radio reception, data
logging status, Wi-Fi, and power. Bluetooth wireless technology provides cable-free
communications between the receiver and controller.
You can use the SPS985 smart antenna as part of an RTK GNSS system with the Trimble SCS900 Site
Controller software. The receiver can optionally record GPS data to the receiver’s optional internal
memory and download to a computer using the serial connection.
The GNSS smart antenna has no front panel controls for changing settings. To configure these
receivers:
l
In real time, use external software such as the SPS web interface, HYDROpro™ construction
software, or the WinFlash utility.
l
Use an application file. To edit an application file, use the Configuration Toolbox utility.
