At the core of Meridian II is a proprietary, time-and-frequency-optimized, GPS receiver that provides industry-leading time accuracy (<10 nanoseconds RMS) and frequency accuracy (<6x10-14 one day average) to UTC(USNO).  For ultimate performance, the innovative Real-Time Ionospheric Corrections (RTIC) option compensates for ionospheric delay in real-time that meets the performance of L1/L2 solutions.  Meridian II can be configured with our individually-characterized oven oscillator options and provide spectrally pure 5 MHz or 10 MHz outputs with state-of-the-art phase noise performance (<-115 dBc/1 Hz offset at 5 MHz).

The network-centric Meridian II provides dual-gigabit Ethernet ports that are security hardened to meet the highest Information Assurance (IA) requirements.  A built-in stratum 1, Network Time Protocol (NTP) server is enabled with a high performance packet timing engine (7500 NTP packets per second).  An optional PTP/IEEE-1588 Grandmaster provides specialized PTP hardware time stamping (8-nanosecond resolution).

Designed for mission-critical applications, Meridian II is based on a high reliability platform with a conservative MTBF of 20 years.  The product is made in America, supported with free software upgrades, and free technical support (if needed), resulting in the lowest total cost of ownership in the industry and backed by our Satisfaction Guarantee!
