H-GPS Time and Frequency GPS Clock
The H-GPS is a high performance GPS clock used for highly accurate time and frequency signals. A GPS Clock is a combination of a GPS receiver and a high quality, stable oscillator. GPS is used to calibrate the oscillator to remove small biases in the frequency. The GPS Clock can synchronize both system timing and transceiver frequency, and is virtually fail-safe. It generates timing signals whenever there is power, and never needs to be re-calibrated. This is useful in any application where accuracy and stability are required. The H-GPS is popular in digital timecoding applications for media broadcast as well as in military and scientific applications.
