The GT-100 from Furuno is a Multi-GNSS Timing Receiver Module that supports L1/L5 band reception. It delivers three outputs, including 1 pulse per second (1PPS) synchronized with UTC as well as user-programmable frequencies. The outputs can be set as required to 10 MHz, 2.048 MHz, 19.2 MHz, etc., commonly used in a variety of wireless communications systems. It has best-in-class time stability of less than 4.5 ns (1 sigma) and is equipped with Dynamic Satellite Selection™ (DSS) which is a multipath-resistant algorithm developed by NTT that minimizes degradation of time performance even when the antenna is installed in urban areas or near a window. This module is compliant with G.8272 PRTC-A and PRTC-B.

The GT-100 supports short-term holdover, which maintains constant performance even if GNSS satellite signals are interrupted for a short period of time. This module mitigates the effects of jamming signals automatically and provides real-time notification to the user of the jamming signal frequency and signal strength. It enhances receiver security and identifies the source of jamming during the operational phase of a customer's system. This module also implements a detailed algorithm to verify the correctness of GNSS signals and can detect and eliminate spurious signals that are not broadcast from the satellites. The GT-100 also has the ability to operate only on L5 if L1 is jammed, or only on L1 if L5 is jammed.

The GT-100 has 62 channels for GNSS reception, an acquisition sensitivity of -147 dBm, and a tracking sensitivity of -165 dBm. It requires a DC supply of 3.3 V and consumes 55 mA of current. This module is available in a 47-pin LCC package that measures 18.00 x 17.80 x 3.11 mm. It is suitable for use in 5G RAN, radio systems, and time servers.
