Trimble SNR920 On Machine Radio

Rugged, 900MHz SNR920 On-Machine Radio for Grade Control Systems

The Trimble® SNR920 is a multi-network, 900MHz on machine radio designed specifically for use on grade control system applications for the construction and mining industries. The SNR900 on machine radio has been designed for use within a Trimble GCS900 Grade Control System. It offers outstanding features and benefits for on-machine applications:
  • Increased robust power handling allows direct connection to machine power for easier installation and cabling
  • Controller Area Network (CAN) communication with the GCS900 system provides a simpler, more reliable system
  • Error correction and a high-speed data rate ensures maximum performance
  • Designed for reliable operation in demanding RF environments and optimized for GPS with increased sensitivity and jamming immunity

The SNR900 on machine radio can be used as a replacement radio on Trimble SiteVision® systems. This rugged unit is fully sealed against dust, rain, splash, and spray for optimal reliability in all weather conditions to minimize downtime and lower overall operating costs.
