NTP80 Plus - Stratum 1 NTP Time Server

A popular, triple port, cyber hardened, GPS based Master Clock NTP time server unit.  The three NTP ports are hardware and firmware isolated with protocol choice programmability .


Offered with a choice of oscillators and GPS antennas.

The NTP80 Plus Stratum 1 GNSS/GPS multi-network NTP Master time clock system is an advanced, cyber secure, high precision master clock timing platform that is commonly specified for use in critical network timing applications that depend upon a reliable, quality time standard.  

Built to demanding AS9100C aerospace quality standards, the unit offers three truly independent and isolated NTP network ports, each of which can be individually configured for network security and access levels.  

The unit is readily configured as a Stratum 1 Master Time Clock reference server or as a Peer to Peer sub-master client in order to form a multi-network distributed time system.

Options include a choice of TCXO, OCXO or Rubidium oscillators together with a choice of standard or long distance antennae.

Constellation options are user selectable via the 32 channel C/A GNSS/GPS antenna covering GPS, GLONASS & BEIDOU combinations.

Features

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

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

   •  TCXO, OCXO and Rubidium disciplined oscillator options

   •  IRIG Synchronisation option available as an alternative to GNSS

   •  3 Fully isolated, secure and independent NTP ports supporting up to 1500 clients

   •  Stratum 1 Triple port NTP Server mode

   •  Peer-to-Peer client mode - Sub master clock operation and NTP distribution mode

   •  Client NTP system accuracy within 50 µs to UTC

   •  Automatic holdover switching

   •  1pps output - 100ns accuracy to UTC On Time Sync Signal

   •  Configurable Serial Time Code Output via RS232/ RS422 port

   •  Non-volatile internal event log

Input Options

   • Satellite GPS via High Gain Active Antenna or Long Distance Remote Antenna System

   • Analog timecode, e.g. IRIG-B, AFNOR NFS-87500 (see over for full list)

   • NTP (Peer-to-Peer)

   • LF (MSF, DCF-77, etc)

Typical Applications

The NTP80 Plus is commonly specified where high reliability and cyber security are key considerations in the network application.  

These high integrity units are common place and thoroughly proven worldwide in network timing applications such as airports, rail/transit networks, financial institutions and  exploration installations where traceable, precision time stamping and time distribution is required.  

The robust design and unrivalled build quality delivers exceptional performance and trouble free product field longevity.  Commonly specified in air traffic control systems, broadcasting, CCTV security systems, computer and communications networks.
