NLC-RCB-GT-100

The NLC-RCB-GT-100 is a carrier board based on the robust  Furuno GT-100 GNSS chip, which provides exceptional sensitivity and acquisition times for all dual-band (L1/L5) GNSS systems.

The NLC-RCB-GT-100 is a multi-GNSS receiver module for time synchronization that delivers high-stability, high-resolution time pulse (1PPS) and programmable clocks. 1PPS achieves the time stability of less than 4.5ns (1σ), which is required by the most demanding applications such as 5G mobile base stations.

The NLC-RCB-GT-100 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. The user no longer needs to convert 1PPS to the desired frequency.

Interruption of GNSS satellite signals is a major concern during operation of critical infrastructure systems.

NLC-RCB-GT-100 supports short term holdover, which maintains constant performance even if GNSS satellite signals are interrupted for a short period of time. Also, dual-frequency band positioning (L1 and L5) mitigates the effects of ionospheric delays caused by solar flares, etc.

Jamming and spoofing are anticipated problems that may occur after a system with a built-in GNSS receiver for time synchronization is put in to operation.

NLC-RCB-GT-100 has counter measure functions against these threats and can be used safely and securely in critical infrastructure applications.

The NLC-RCB-GT-100 also performs well not only in ideal environments with open skies, but also in urban areas with mixed multi-paths. Proprietary Dynamic Satellite Selection™ technology (DSS), which appropriately chooses only the high-quality satellite signals, minimizes degradation of time stability.

Time stability of less than 4.5ns (1σ) is achieved even when receiving only L1 or L5. NLC-RCB-GT-100 can operate only on L5 if L1 is jammed, or only on L1 if L5 is jammed. The main applications of NLC-RCB-GT-100 include 5G mobile base stations, police radios, emergency services radio systems, train radios, and time servers. Highly robust GNSS receivers for time synchronization, which contribute to strengthening the customer's competitiveness, are also deployed in the latest 5G mobile base stations.
