Timing Systems

Our time and frequency products use the capabilities and accuracy of a GPS satellite synchronized clock to deliver pulse-per-second and frequency reference signals for many industries.

From wireless infrastructure and base station timing, to laboratory reference and event time stamping-timing modules, boards and standard products to satisfy your needs.

Thunderbolt E

The Protempis® 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 wireless local loop. The architecture is comparable to systems currently used to maintain the tough CDMA holdover specification. This makes the Thunderbolt E GPS clock a natural for a CDMA clock, the digital standard for cellular phones.
