GNSS Radios for Construction
Trimble GNSS radios enable fast, reliable data communication between base stations and rovers on construction sites. Designed for rugged conditions and flexible configurations, these data radios ensure high-accuracy RTK corrections are transmitted with minimal delay, keeping your crews productive and connected in real time. Whether you’re operating in spread-out terrain or dense urban zones, Trimble radios deliver dependable GNSS signal transmission where it matters most.
Frequently Asked Questions About Trimble GNSS Radios
What is a GNSS data radio and why is it important in construction?
A GNSS data radio transmits correction signals from a base station to rover receivers in real time. This communication is critical for achieving high-precision positioning in construction workflows like layout, grading, and surveying.
What’s the difference between the TDL 450B and the TDL 450 Series?
The TDL 450B is a high-power, rugged UHF radio ideal for long-range communication in tough environments. The TDL 450 Series includes multiple models with flexible frequency support and configuration options for a variety of site conditions.
Are Trimble GNSS radios compatible with all GNSS systems?
Trimble radios are designed for seamless integration with Trimble GNSS receivers, but they also support widely used protocols and frequency bands for compatibility with other systems.
Can I use Trimble GNSS radios in urban or obstructed environments?
Yes. Trimble GNSS radios are engineered to maintain strong, stable communication even in challenging environments with buildings, trees, or terrain obstructions.
