The Trimble Thunderbolt® PTP Grandmaster Clock is designed for the telecom market, for use at the edge of wireless networks requiring phase synchronization. The GM200 provides continuous availability of UTC traceable time for phase synchronization, a must for LTE-Advanced networks and services.

The Thunderbolt PTP GM200 employs industry-leading Trimble GNSS performance, and world class holdover technology.

The PTP GM200 tolerates harsh environmental conditions, supporting both indoors & outdoors deployments with extended operating temperature range (-40 to +85 C).

The Thunderbolt PTP GM200 supports small cells networks that require phase synchronization. Although it is designed with keeping small cells in mind, it meets Marco base station requirements for synchronization.

Due to the Trimble GM200’s small size, low cost, superior accuracy, reliability and flexibility of deployment options, the risk of network re-configuration and load variance on IEEE-1588 signal quality is reduced.


  • Low cost reduces CAPEX of LTE TDD, LTE-A & small cell projects

  • Extended environmental capabilities enable deployment in difficult locations where small cells and LTE-A base stations are deployed

  • Superior holdover performance via Trimble proprietary technology gives extra time error budget for network design and dimensioning
