Product Overview

Today small cell in the mobile network and IEC61850 power-grid requires high time accuracy. OGM-64 offers you a simple and effective solution for synchronization by GNSS receiving. It combines GNSS antenna, GNSS receiver, and PTP/NTP GrandMaster Clock functions in one compact weatherproof housing, which allows you to install simple and cost-effective time master without RF cabling. OGM-64 supports PTP as master and NTP as time server. Also it supports both IPv4 and IPv6 for packet traffic.
