SPS 781 & 881 Rover Receivers

The Trimble® SPS781 and SPS881 Smart GPS Antennas provide a rugged and highly portable GPS base station and rover solution for grade checkers and site engineers on site development or highways projects that require precise site measurement and stakeout capability.

The SPS781 and SPS881 Smart GPS Antennas can operate in Location GPS modes with Satellite Based Augmentation Systems (SBAS), as a rover in Real–Time Kinematic (RTK) mode with corrections from a site base station, Internet base station or VRS™ network and can act as a site base station for RTK operations.

In combination with the Trimble SCS900 Site Controller Software, the receivers provide the capability to:

• Determine cut fill anywhere on the jobsite

• Stake out site or road features, utilities, daylight lines and side slopes

• Carry out site measurements for progress and material stockpile volume computations

• Carry out as–built measurements, grade checks and laid material thickness checks

Easy Setup Saves Time and Money

The Trimble SPS781 and SPS881 models are easier than ever to set up. The SPS781 and SPS881 Smart GPS Antennas make setup for base station and rover operation quick, easy and hassle–free.

Base Station Operation

• One component to set up

• One button to start up using AutoBase technology

• Bluetooth cable–free operation when using a controller

• Easy to understand status LEDs that show receiver is switched on, tracking satellites and transmitting corrections

Rover Operation

• One component to set up

• One button to start up

• Bluetooth cable–free operation

• Automatically connect using the last used rover settings and source of corrections

• Easy to understand status LEDs that show receiver is switched on, tracking satellites and receiving corrections

Rover set up is fast and easy–just switch on the receiver, start up the controller and you’re ready to go. And, because the GPS receiver, GPS antenna, radio, radio antenna and battery are integrated into one housing, you don’t have to deal with cables and multiple components. It saves time and money by making them simple to transport and fast to setup.

Trimble AutoBase functionality provides users with rapid repeat daily set up of the base station without the need for a controller.
