GT-9001

The GT-9001 delivers accurate 1PPS synchronized with UTC with high resolution.
The GT-9001 also includes three output clock signals.The three outputs can be arbitrarily assigned to 1PPS and clock.
The GT-9001 clock outputs can be set as required to 10MHz, 2.048 MHz, 19.2 MHz, and 30.72 MHz, which are commonly used in wireless communications.
This shortens the time-to-market and contributes to strengthening the customer's competitiveness.

Compliant with TDEV (Time Deviation) /MTIE (Max Time Interval Error).
Exceeds the most stringent requirements in 5G networks.

Multi constellation capability supporting GPS, GLONASS, Galileo, Beidou, QZSS and SBAS from various countries.
The GT-9001 can be used with a selection of positioning satellites or all of them concurrently, making it ideal for globally deployed 5G mobile base stations and network equipment.

The use of GNSS receivers for time synchronization is growing vastly into urban areas where multipath signals are mixed and cause severe degradation of timing accuracy. Our proprietary "Dynamic Satellite Selection™*" technology, which appropriately chooses only the high quality satellite signals, minimizes degradation of time synchronization performance in poor reception environments.
This technology can be used safely even at base stations installed in urban areas.

* Multipath resistance technology based on an algorithm developed by NTT

The GT-9001 mitigate the effects of jamming signals automatically and to provide real-time notification to the user of the jamming signal frequency and signal strength.
The modules enhance receiver security and identify the source of jamming during the operational phase of a customer's system.
The GT-9001 also implement a detailed algorithm to verify the correctness of GNSS signals and can detect and eliminate spurious signals that are not broadcast from the satellites.

Interruption of GNSS satellite signals is a major concern during operation of critical infrastructure systems.
GT-9001 support short term holdover, which maintains constant performance even if GNSS satellite signals are interrupted for a short period of time.

GT-9001 accept an external time reference input (1PPS, clock) that is different from that of the GNSS satellites. The input can be derived from an external clock, enabling the modules to continue to provide service even in the unlikely event of loss of signal from the GNSS satellites.

Compared to conventional GNSS receivers for time synchronization, Furuno's new GNSS receivers are substantially more robust (i.e., they are not affected by most disruptions and thus ensure continuous service).
Such enhanced features give users a high level of confidence in fields that require high reliability, such as 5G mobile base stations, financial transactions, and power grids.
