Description:
GT-804 is a 1U rackmount GNSS Disciplined Oscillator (GNSSDO) which supports 4 pairs of 1PPS and 10MHz clock outputs on the back panel. GT-804 is equipped with the u-blox M8, Multi-GNSS, high-sensitivity timing engine, OCXO, DPLL/DCO, and SoC. This GNSSDO provides stable 1PPS and 1PPS synchronized 10MHz clocks. The holdover time of ±1.5us is better than 4 hours. GT-804 supports positioning of multi-satellite systems – GPS, GLONASS, GALILEO, BEIDOU, QZSS, SBAS. Vast number of visible satellites allows stable and better clock quality of 1PPS/10MHz. Additional filtering design makes clocks even more stable.
