  Trimble SPS881 Smart GPS Antenna
The Trimble® SPS881 Smart GPS Antenna provides 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 SPS881 Smart GPS Antenna 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 SPS881 model is easier than ever to set up.

The SPS881 Smart GPS Antenna 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.

Integrated radio
The SPS881 Smart GPS Antenna has a integrated license–free 900 MHz spread spectrum or 450 MHz UHF radios for receiving or transmitting base station corrections. The Smart GPS antenna can be used with cellular communications for connection to VRS networks, Internet–enabled base stations for long–range operation and to provide infill for areas where base station corrections are unavailable over radio.

A future–proof investment
Available in a range of options to suit your application and performance requirements, versatile Trimble GPS receiver is a future-proof investment.

The SPS881 Smart GPS Antenna is designed to receive current and future satellite signals. This receiver supports GPS modernization through support of L2C code and can be upgraded to receive GLONASS or L5 GPS signals, protecting your investment well into the future.

Improved GPS Performance
The new Trimble RTK engine improves performance under tree canopy and reduces initialization time after loss of lock, delivering high performance in a variety of measurement conditions.

Every innovative feature on the TSC2 controller is designed to make your job easier. Clearly view background maps and check work on the vibrant color graphic display for greater data control and confidence. Use the full alphanumeric keyboard, or quickly select software options using the touch screen.The unique TSC2 controller changeable cap enables the use of removable memory or third-party media, such as GPRS, GPS, camera, and product scanner functions. Extend your data logging capabilities and experience a major leap in productivity.

Eliminate cable hassles and expedite setup with integrated Bluetooth® wireless technology. When the TSC2 controller is used with a Trimble R8 or 5800 GPS system, the rover is 100% cable free for unsurpassed convenience and ease of use. The internal 2.4 GHz radio option is ideal for use with a robotic system such as the Trimble S6 total station.
Using the expandable media function, a GSM/GPRS modem can add full wireless communication to the Internet in the field.Transfer data in your office over a wireless 802.11 LAN—again, no cables are required. You can also use hotspots to quickly and securely share data with your office from remote locations.

Choose the method of data transfer that suits your situation. Using an external modem such as a cell phone with Bluetooth, send and receive files over the Internet from the field: you don’t need to drive back to the office. In the office, internal 802.11 technology provides wireless connection to your network. The TSC2 controller also provides USB and serial RS232 communication options; data can be transferred to a PC or another TSC2 controller using a cable, Bluetooth, CompactFlash, or Secure Digital memory card media.

The TSC2 controller is central to Integrated Surveying™ from Trimble. With an application such as the Trimble Survey Controller™ software onboard, collect and manage both GPS and optical data in one Job file simply by switching the TSC2 controller between sensors. Standardize on one flexible controller for maximized investment. And your survey team only needs to know one interface. When field work is complete, simply transfer the Job file to your office using the communication method that suits your needs.
