Resolution-SMT GPS receiver

Trimble has introduced an embedded GPS receiver for timing applications. The Resolution-SMT GPS receiver enables system integrators to add precise GPS to provide location, Coordinated Universal Time (UTC) and synchronization to many products or systems where cost or size had previously been a limitation.

Precise timing and synchronization is vital to today's wireless infrastructure, efficiently controlling the flow of network information data to maximize the use of bandwidth. The Resolution-SMT receiver provides a low-cost, easy to use, highly accurate and reliable GPS timing source for the telecommunications, broadcast synchronization, power transmission and wireless industries.

The Resolution-SMT is a complete, ready-to-go timing receiver in a 19mm x 19mm x 2.5mm shielded module. The small, thin, single-sided receiver is packaged in tape and reel for pick and place manufacturing processes. It features a reflow-solderable edge castellation interface so the module can be incorporated in a product design without costly I/O and RF connectors.

Timing features of the Resolution-SMT receiver include: automatic self-survey to ensure accurate reference position for improved timing accuracy; the overdetermined timing mode provides an accurate 1 PPS synchronized to GPS/UTC within 15ns (one sigma); timing receiver autonomous integrity monitoring (T-RAIM) to assure high PPS integrity in overdetermined timing mode; and other features. The modular design also allows for reduced integration time and low implementation risk.

The Resolution-SMT Starter Kit equips designers who need to begin adding the latest GPS timing capability into their application. The Resolution-SMT receiver uses Trimble Standard Interface Protocol or NMEA.

The Resolution-SMT receiver and starter kit are available now through Trimble's worldwide Component Technologies sales network.
