Resolution SMT GG
Trimble Resolution SMT GG module is a multi-GNSS (GPS, GLONASS, QZSS, SBAS) receiver, optimized to generate precise timing signal. Designed specifically for integration on a circuit board using surface mount technology. When operating in Over Determined Timing Mode the accuracy of pulse per second (PPS) is within 15 nanoseconds of GNSS/UTC.

Lowers total cost of operation
The Resolution SMT GG lowers your total cost of operation by reducing the form factor to enable this timing functionality in the most compact user applications. Measuring only 19 mm x 19 mm, its small size and surface-mount package makes it the ideal choice for high-volume manufacturing applications

Standard Timing features
The Resolution SMT GG includes many of Trimble’s standard timing features, including the Timing Receiver Autonomous Integrity Monitoring (T-RAIM) algorithm, and automatic self-survey.

Starter Kit and Carrier Board Options
The Resolution SMT GG board may be loaded directly onto the customer application board, or can be purchased on a carrier board for integrators who prefer the traditional form factor of the original Resolution T™.
The Starter Kit provides everything you need to evaluate the Resolution SMT GG board, including the Resolution SMT GG on a carrier board, AC/DC power converter, antenna and USB interface cable.
