Trimble SPS852 Modular GPS Receiver FLEXIBLE RECEIVER FOR JOBSITE MEASUREMENT Whether you need a reliable GNSS base station or a rugged rover, the Trimble® SPS852 GNSS Modular Receiver gives you the flexibility to do all of your construction site measurements. As a permanent or semi-permanent base station, it provides GNSS corrections for site measurements and machine control. As a rover, it can move easily from a site supervisor truck to a pole mount for grade checking, site measurement and stakeout. The versatile SPS852 receiver is available in a range of options to suit your jobsite or marine construction performance requirements. Simply purchase the receiver that you need today, and upgrade as your needs change. Secure and Easy to Use The Trimble SPS852 is comprised of an integrated GNSS receiver and radio plus a choice of external antenna. The receiver can be placed in a secure environment such as the job trailer or boat cabin where it is protected from theft and weather. The less expensive antenna can be placed in a location with clear visibility to the sky and maximum radio coverage. You don’t have to be a GNSS expert to use the SPS852. Integrated 900 MHz license-free radio and interface with Trimble SCS900 Site Controller Software make the SPS852 easy to use, fast to setup and more productive on the job. Trimble Autobase™ technology means anyone on the jobsite can perform daily base station set up with one button push. For more advanced troubleshooting, the receiver’s web interface allows your GNSS manager to remotely monitor base station performance, availability, and configuration. No need for time-consuming and costly visits to the base station to set up each day or diagnose issues that may arise. You don’t have to be a GNSS expert to use the SPS852.

Trimble Zephyr Model 2 GNSS Antenna The new Trimble® Zephyr™ 2 and Zephyr Geodetic™ 2 antennas break new ground in GNSS surveying antenna technology. Both antennas support modular Trimble systems such as the Trimble® R7 GNSS and Trimble® 5700 GPS receivers, and can be used as part of the Trimble GNSS Infrastructure solution. The Trimble Zephyr 2 GNSS antenna is typically used in roving applications. It minimizes multipath, and offers robust low elevation tracking and sub-millimeter phase center repeatability A Trimble GNSS rover comprising the rugged Zephyr 2 and a receiver such as the Trimble R7 GNSS is extremely flexible: Attach the antenna to the top of a pole, wear it on the purpose-built Trimble backpack, or drive with the Zephyr 2 mounted on the roof of a vehicle. The Trimble Zephyr 2 supports the way you want to work. COMPREHENSIVE GNSS SUPPORT The Trimble Zephyr 2 and Zephyr Geodetic 2 antennas offer full support for coming and near-future GNSS signals, including GPS L2C and L5, GLONASS, and even Galileo. This technology future-proofing, in combination with the rugged durability of each antenna, means any investment in a Trimble Zephyr GNSS antenna will last for many years. Features:
- Comprehensive GNSS support, including GPS Modernization signals, GLONASS, and Galileo
- Robust low-elevation satellite tracking
