GF-8802 outputs 1PPS synchronized with UTC as well as 10MHz coherent to 1PPS.
UTC time-synchronized signal performance to meet 5G requirements is obtained without any changes to existing single-band GNSS antennas.
It also incorporates Dynamic Satellite Selection™, which is a new satellite signal selection algorithm developed by NTT. Thanks to that GF-8802 permits GNSS antennas to be mounted more freely than ever before including wall mounting and window mounting installations.
Ultra-small size form factor featuring atomic clock level frequency stability with 24h holdover.
GF-88 series is a full-featured multi-GNSS disciplined oscillator (GNSSDO), embedded with multi-GNSS receiver, OCXO, LDO regulator and antenna detection circuit in a compact pin-header module. It provides outputs of one-second pulse (1PPS), synchronized with Coordinated Universal Time (UTC), and reference frequency (10MHz) signal.
Combined with ultra-miniature OCXO, GF-8802 (approx. 34mm x 27mm) builds up a holdover function which can maintain within 10μs / 24 hours(ex.GF-8803) in case that GNSS falls into unlock.
