GPS Disciplined Oscillator Model GF-8052Discontinued Products

For Timing

The Furuno GF-8052 is a GPS Disciplined Oscillator that has an OXCO as a base oscillator.

By using GPS as a reference the GF-8052 realizes complete maintenance-free high stability OXCO oscillator. The stability of the GF-8052 is higher than that of Rubidium oscillators and Cesium oscillators. Even if it receives one satellite signal, it generates 1PPS (pulse per second) synchronized with UTC as well as 10MHz sine wave and square wave coherent to 1PPS.
The GF-8052 can synchronize with SBAS satellites (WAAS/MSAS/EGNOS). It continues to operate as a frequency generator even if the GPS satellite signals are interrupted due to emergency situations. It has a “holdover” function that enables it to maintain high clock accuracy even if GPS loses the GPS/SBAS satellite signals. The combination of the GF-8052 and the Furuno GPS antenna contributes to it being jamming-resistant.

Features

  • Highly-stable frequency and high accurate UTC time can be easily obtained worldwide.

  • The GF-8052 can continuously output high accurate and stable 1PPS and 10MHz even if the GPS receiver loses the GPS satellite signals in holdover mode.

  • The GF-8052 realizes the coherency within ±2ns accuracy between the rising edge of 1PPS and the zero crossing of 10MHz sine wave.

  • The GF-8052 can synchronize with SBAS satellites (WAAS/MSAS/EGNOS).

  • Designed specially for wireless broadband base stations for CDMA, WiMAX and LTE and for multimedia broadcast base stations.
