GP-1000 GPS and GNSS NTP Server

GP-1000 NTP Time Server

GPS and GNSS receiver with IRIG-B, 1PPS outputs

KEY FEATURES DATA SHEET

Overview

The GP-1000 The GP-1000 NTP Time Server, is a compact DIN Rail mount time server which efficiently serves GPS time to NTP clients while also providing precise GPS synchronized timecode via 1PPS and unmodulated IRIG-B outputs. The time server is ideal for private networks requiring enhanced security as it ensures complete isolation from public networks.

The GP-1000 NTP Time Server supports SHA-1 and MD5 authentication for NTP requests, enhancing the security of NTP clients. It also provides comprehensive SNMP monitoring and logging, enabling efficient alarm tracking through SYSLOG and SNMPv3. In addition, the GP-1000 NTP Time Server integrates seamlessly with existing enterprise directories via RADIUS for user authentication.
