GT-9001
Timing Multi-GNSS Receiver Module
Highly precise time & ultra-low
jitter 1pps synchronized with UTC
The world‘s highest level of stability under open sky <4.5ns (1σ)
Single-frequency band positioning system with excellent cost
performance
World's lowest accuracy degradation in harsh urban multipath

environments
Delivers high stability 1PPS synchronized with UTC andprogrammable clocks on three channels
The GT-9001 is a Multi-GNSS receiver module for timesynchronization that delivers high-stability, and high-resolution
time pulse (1PPS) and programmable clocks. 1PPS achieves thetime stability of less than 4.5ns (1σ), which is required for 5G
mobile base stations, using single-frequency band reception.
GT-9001 clock outputs can be set as required to 10MHz,
2.048MHz, 19.2MHz, and 30.72MHz or other frequencies
which are commonly used in wireless communications. Thisshortens time-to-market and increases the customer's
competitiveness by reducing component count.

GPS+QZSS/SBAS●GLONASS●Galileo●BeiDou●The GT-9001 also performs well not only in ideal environmentswith open skies, but also in urban areas with mixed multi-paths.
Our proprietary Dynamic Satellite Selection™* technology (DSS),
which appropriately chooses only the high-quality satellite
signals, minimizes degradation of time stability. This makes theGT-9001 ideal for 5G mobile base stations and precise PTP
grand master clocks to be installed in urban areas.

Time pulse output (1PPS)●GT-9001 supports short term holdover, which maintains
constant performance even if GNSS satellite signals areinterrupted for a short period of time. It is equipped with antijamming and anti-spoofing functions to ensure safe and secureuse in critical infrastructure systems.

The main applications of GT-9001 include 5G mobile basestations, police radios, emergency services radio systems, train
radios, and time servers. Furuno's GNSS receivers for timesynchronization, which contribute to strengthening thecustomer's competitiveness, are also deployed in the latest 5G
mobile base stations. GT-9001’s sophisticated built-in security
including secure boot and secure firmware update ensuresmaximum protection against tampering.
