Trimble ICM SMT 360 Carrier - Multi-GNSS Timing Module

Ideal Solution For Mobile Products, Precise Timing When You Need It

Introduction

Introduction

Trimble® designed the ICM SMT 360™ Timing Module to work in the most demanding weak signal environments, including femtocells and in-building systems. With its robust performance in low signal environments, users can save on expensive cabling and externally mounted antennas. In addition, the ICM SMT 360™ timing module accepts aiding data for environments requiring the highest levels of enhanced sensitivity.

PPS and Frequency Outputs

The ICM SMT 360™ timing module outputs a precise1 pulse-per-second (1PPS) and 10 MHz frequency to maximize your network performance and synchronize systems at a global level. Custom frequencies are also available for volume sale.

Standard Timing features

The ICM SMT 360™ timing carrier includes many of Trimble’s standard timing features, including Time-Receiver Autonomous Integrity Monitoring (T-RAIM) algorithm, automatic self-survey, and GNSS disciplining of the oscillator to provide an accurate frequency reference.

Starter Kit

The ICM SMT 360™ timing carrier can be loaded directly onto the customer’s application board. The Starter Kit provides everything you need to evaluate the ICM SMT 360™ timing platform, including the ICM SMT 360™ on a carrier board, AC/DC power converter, antenna and USB interface cable.
