Time SynchronizationProduct Catalog • GNSS Disciplined Oscillator (GNSSDO) • GNSS Timing Module • GNSS AntennaFURUNO technology Extremely high stability of 4.5 ns (1 sigma) using a single band GNSS timing receiver UTC time-synchronized signal performance to meet 5G requirments is obtained without any changes to existing single band GNSS antennas. GNSS antennas can be mounted on walls and windows of tall buildings The Dynamic Satellite Selection™ minimizes deterioration of time synchronization performance by choosing only the high quality satellite signals. * a new satellite signal selection algorithm developed by NTT Industry-leading holdover performance (GF series) Provides highly accurate timing signals even if satellite reception is lost due to antenna failure or jamming issues.

FURUNO technology made it possible to achieve 5G-required performance. 4.5 ns (1 sigma) by a single band receiver is obtained. The receivers are in comformitity with G.8272 PRTC-B. This is achieved by an improved and advanced position estimation algorithm. It optimizes position calculations using several different GNSS satellite constellations. It allows users to achieve 5G-required performance without changing existing single band GNSS antennas. GNSS antennas can be mounted on walls and windows of tall buildings GT-88 Significantly improved Normally typical time synchronization performance...
