PTP80 Elite - PTP (IEEE1588) GrandMaster Clock

This Stratum 1 GNSS/GPS based PTP GrandMaster and Boundary time clock system is an advanced, cyber secure, high precision master clock timing platform that generates and distributes precisely synchronised time to PTP clients and slaves. Offered with a choice of oscillators and GPS antennas.

This Stratum 1 GNSS/GPS based PTP GrandMaster and Boundary time clock system is an advanced, cyber secure, high precision master clock timing platform that generates and distributes precisely synchronised time to PTP clients and slaves across packet networks using the PTP (Precision Time Protocol) in accordance with IEEE-1588v2.

The platform delivers excellent time and frequency accuracy using a tried and tested hardware based time stamping system which operates in combination with a choice of high precision disciplined oscillators serving to ensure precise time information is available even in the event of GPS signal loss.

Units can be configured as GrandMaster, Boundary Clock or PTP slave while providing multiple output formats including 1PPS, 10MHz, E1/T1, IRIG-B and NTP (RFC1305). Multiple PTP80 Elites can be configured for load sharing resilience and increased network support.

Options include a choice of Oven Controlled or Rubidium oscillators together with a choice of standard or long distance antennae.  

Constellation options are user selectable via the 12 channel C/A GNSS/GPS antenna covering GPS, GPS/GLONASS & GPS/BEIDOU combinations.

Features

•   12 Channel GNSS/GPS receiver synchronised - Standard and long Distance Antenna options

•   Constellation selections : GPS, GPS/GLONASS, GPS/BEIDOU

PTP80 Elite datasheet

Overview

Combining a Linux operating system with a high performance embedded single board controller and custom hardware based time stamping engine, the PTP80 Elite delivers exceptional levels of cyber security and operational accuracy and reliability.

A 12 channel C/A GPS receiver delivers high coverage and rapid GNSS sync lock (GPS/GLONASS/BEIDOU) while physical 1PPS, 10MHz, IRIG-B and E1/T1 timing signal outputs are made available at rear panel BNCs, allowing other equipment to be readily synchronised.  

A high contrast 40 x 2 LCD display and 5 button menu navigation console provides real time system information about the GNSS - GPS/GLONASS/BEIDOU satellite status, network status, system sync status and fault conditions.  

Two 10/100/1000 BaseT Ethernet ports provide network connectivity supporting PTP, NTP and remote system management which is made available via an intuitive built in web browser configuration and management suite.  

Multiple network protocols are supported and selectable as is an RS232/RS422 port that provides a Time of Day NMEA GPRMC message.

Standard antenna options provide for unit to antenna distances of up to 150m (500ft), while a proprietary “head-end” antenna option allows operation up to distances of 500m (1600ft).
