The Trimble Internet Base Station Service (IBSS) enables the transmission of Real-Time Kinematic (RTK) or Differential GNSS (DGNSS) correction data from a base station over the internet using Wi-Fi or cellular networks. This approach extends the effective range of high-precision GNSS positioning and machine control beyond the limitations of traditional UHF radio links. IBSS also serves as a valuable supplement in areas where UHF coverage is limited, offering a more flexible and cost-effective solution for maintaining reliable connectivity across the construction site.

The Trimble® SPS855 GNSS Modular Receiver is designed for use as a permanent or semi-permanent base station, making it ideal for large-scale construction sites that require both site positioning and machine control. This versatile receiver supports a range of configurations and can be paired with an external antenna of your choice to complete a customized base station setup. Its robust design and flexible deployment options make it a reliable solution for maintaining high-accuracy GNSS corrections across complex jobsite environments.

Trimble VRS Now is a Network RTK subscription service that delivers high-precision GNSS corrections via the internet over a cellular connection. Designed for construction environments where setting up a physical base station is impractical—such as sites without machine control or during early reconnaissance—VRS Now provides a flexible and efficient alternative. By leveraging Trimble’s advanced VRS technology, users can access centimeter-level accuracy on demand, anywhere within the supported reference station network. The service requires an internet-connected rover and offers a cost-effective, user-friendly solution that is continuously available and ready to support a wide range of positioning tasks.

Trimble CenterPoint RTX is a high-performance GNSS correction service that delivers RTK-level accuracy via satellite or cellular connection, making it ideal for construction sites around the world. The service operates in real time using geo-stationary L-band satellites, with corrections received directly by a Trimble GNSS Antenna or GNSS Smart Antenna. This eliminates the need for UHF radios or cellular network infrastructure, offering a reliable, always-on solution for precise positioning. CenterPoint RTX is especially valuable in remote or challenging environments where traditional correction methods may be limited.
