EndRun Launches Two GPS-Based Timing Units

October 7, 2015  - By

EndRun Technologies has launched two GPS-based timing products.

EndRun_Meridian2_Mirror

Meridian II Precision TimeBase.

The Meridian II Precision TimeBase references GPS to provide ultra-accurate time (10 nanoseconds to UTC) and frequency. At the core of Meridian II is a new GPS receiver that EndRun optimized to deliver a variety of traditional- and network-based time and frequency signals.

“The second-generation Meridian II continues EndRun’s heritage of pushing the envelope by delivering an industry-best, UTC time accuracy of 10 nanoseconds.” said Ron Holm, marketing manager, EndRun Technologies. “Meridian II also introduces a security-hardened, high-bandwidth network interface to synchronize evolving, network-centric applications via the Network Time Protocol (NTP) and IEEE-1588 Precision Time Protocol (PTP). Frequency standard customers will be happy to know that the revolutionary ultra-low phase noise and short-term stability performance of the original Meridian continues to be provided.”

EndRun_Tycho2_Mirror

Tycho II Precision TimeBase.

Also new is the Tycho II Precision TimeBase time and frequency standard, which references GPS to provide exceptional time (25 nanoseconds to UTC) and frequency (<1×10-13 per day) accuracy in a security-hardened, network-centric platform.

At the core of Tycho II is a new EndRun GPS receiver that is optimized to take advantage of improved GPS system accuracy. Tycho II delivers a variety of traditional and network-based time and frequency signals and services via a modular, customer-configurable platform. Operational status is easily monitored via the network interface (HTTPS, SNMP, SSH). Intuitive charts are provided to assess current and historical performance of Tycho II, its GPS receiver and reference oscillator.

“The second-generation Tycho II provides our customers with a cost-effective, high-performance time and frequency standard without compromise to security and reliability,” said Dan Paine, sales and support manager, EndRun Technologies. “In addition, Tycho II uses the same network-centric core of our ultra-high performance Meridian II TimeBase. This enables operation as a high-bandwidth, Network Time Protocol (NTP) server and optional IEEE-1588 Precision Time Protocol (PTP) Grandmaster.”

Both the Meridian II and Tycho II have modular architecture that allows customers to configure them to meet specific application requirements.

The units support mission-critical operations in a wide range of government and commercial applications including telecommunications, satellite communications, digital video broadcast, simulcast radio, test range, test and measurement, calibration labs and power utilities.
