Trimble SNR900 900 MHz Grade Control Machine Radio

Trimble SNR900 Machine Radio
The Trimble® SNR900 machine radio modem enables you to establish a robust, wireless data broadcast network for real-time, high-precision earth moving applications in the construction industry.

The 900MHz frequency offers many advantages for the construction site:

• Virtually immune to inference
• No licensing is required
• Low-latency, high-speed link allows two-way data between office and site machines
• Ideal operating range for construction sites
• Single Radio for ATS or GPS and Two Way IP Data

Designed for Machine Operation
The Trimble SNR900 radio has improved power conditioning over the Trimble SiteNet 900 radio, allowing operation on 12V or 24V machines using direct machine harness power with no intermediate conditioning. The integral antenna, status LEDs and rugged 8-pin connector are durable and waterproof to ensure longevity even under the harshest conditions.

Utilizing 900 MHz spread-spectrum technology, the Trimble SNR900 radio enables seamless network connectivity from office to field. With more memory, more processing power, and 128 kbps over-the-air data rate, the SNR900 is truly the smart choice for your critical wireless networking needs.

License-Free
The Trimble SNR900 radio is certified for license-free operation in the U.S.A., Canada, Australia and New Zealand. This makes the SNR900 radio extremely portable, you can move it from project to project with licensing hassles and restrictions.

900MHz for productivity
Frequency hopping technology and 40 user-selectable networks equate to a reliable network in virtually any radio environment. The Trimble SNR900 radio is a plug in replacement for the SiteNet 900 radio and is fully compatible with existing Trimble 900MHz networks.

This versatile radio operates in the frequency range of 902–928 MHz, receiving real-time GPS corrections and providing two-way data on a single radio. The Trimble SNR900 radio can also communicate with an SNB900 base radio connected to a Trimble ATS Construction Total Station.

The Trimble SNR900 radio is especially suited for use with sensor independent grade control systems, where the multi-functional radio reduces the number of components and reduces complexity. It is ideal for all machine applications where reliability is important. Fully sealed against dust, rain, splash, and spray, the Trimble SNR900 radio remains reliable even in harsh conditions. The radio’s ruggedness and reliability minimizes downtime, lowering ownership costs.
