Atomic GNSS Locked References

GNSS disciplined references use timing information from the GNSS to synchronize a local reference. Long-term accuracy on the order of E-12 is common. The GNSS oscillator can be crystal or atomic with a wide range of performance options depending upon the specific requirement. A range of configurations are available from PCB assembles that can be easily embedded into a system, to rack mount units with up to ten channels. Self-calibrating references essentally eliminate long-term drift by storing the current calibration coefficients for the 10 MHz OCXO in FLASH memory (see demonstartion video). Kits are available complete with the selected GNSS locked source, antenna, power supply and cable - everything you need to have a fully operational source. GNSS locked oscillator products are considered to be frequency standards by NIST (NIST white paper)
