Introduction
Trimble SPS852 Modular GPS receivers are ideal for the following site development and
construction applications:
• Base station for precision GPS applications such as site positioning and machine control
• Location RTK for site vehicle and supervisors
• Precision RTK rover on-site
• System integrator applications using Location GPS augmentation, including OmniSTAR,
Location RTK, SBAS, and DGPS RTCM and Precision RTK
The receiver has a keypad and display, so you can configure the receiver without using a controller or
computer.
All the receivers can optionally record GPS data to the internal memory, and transfer the data over a
serial or Ethernet connection.
