Furuno GT-90

GT-90 is a Multi-GNSS receiver module for time synchronization that delivers high-stability and high-resolution time pulse (1PPS). Time stability of less than 4.5ns (1o), ideal for 5G mobile base stations, is achieved with a singlefrequency band. This offers superior cost performance of the receiver and allows widely available single-frequency antennas to be used for greater total cost reduction. GT-90 support all GNSS using L1 band, making it suitable for integration into globally deployed equipment. The GT-90 also performs well not only in ideal environments with open skies, but also in urban areas with mixed multipaths. Our proprietary Dynamic Satellite Selection technology (Dss), which appropriately chooses only the highquality satellite signals, minimizes degradation of time stability. GT-90 has countermeasures against these threats and can be used safely and securely in critical infrastructure applications. GT-90's sophisticated built-in security including secure boot and secure firmware update ensures maximum protection against tampering.
