The Trimble® Thunderbolt® E GPS Disciplined Clock is Trimble’s latest offering for GPS synchronization devices targeting the wireless infrastructure. This fifth-generation GPS clock combines a 12-channel GPS receiver, control circuitry, and a high-quality ovenized oscillator on a single board, providing increased integrity and reliability at a lower size and cost.

The Thunderbolt E’s level of integration makes it a perfect solution for precise timing applications in the wireless industry. Among its uses are synchronizing the E911 positioning infrastructure and maximizing bandwidth for a wireless local loop. The architecture is comparable to systems currently used to maintain CDMA holdover performance requirements in telecommunications systems.
