About
The NGS-N90 is a 1U/2U rack-mountable GNSS network time server for data centers, telecoms, utilities, and government infrastructure requiring precise, traceable time synchronization. Its 55-channel receiver tracks GPS, SBAS (GAGAN), GLONASS, and IRNSS (L5/S dual-frequency) with position accuracy under 10 metres RMS. Timing accuracy is under 20 nanoseconds RMS relative to GPS, with 8 nanosecond PTP timestamp resolution, simultaneously serving NTP v3/v4 and PTP IEEE 1588v2 to over 5000 clients. Optional Rubidium, OCXO, or TCXO oscillators provide enhanced holdover during GNSS outages. Custom configurations include additional Gigabit Ethernet ports, fibre optic interfaces, and IRIG inputs.
