Note : Your request will be directed to FURUNO Electric Co., Ltd..

The GF-8804 from FURUNO Electric is a Multi-GNSS Disciplined Oscillator that generates a UTC-synchronized 1 pps (pulse per second) reference output signal of 10 MHz. GPS disciplined oscillator, also called as clock module, is a highly accurate timing source that consists of an oscillator and a GPS receiver. The oscillator generates a highly accurate and precise time pulse 1PPS (one pulse per second) 5 MHz or 10 MHz output signal, which can be used as a frequency standard for reference signal. This device supports the concurrent reception of GPS/GLONASS/Galileo/QZSS/SBAS constellations. It provides extremely high 1 pps stability of 4.5ns (1sigma) using a single band receiver, in conformity with G.8272 PRTC-A, PRTC-B. The GF-8804 is available in a package that measures 100 x 52 x 20 mm and is ideal for TRAIM, Single Satellite Tracking, Multipath Mitigation, Anti-Jamming and Anti-Spoofing applications.
