Precision Timing and Reference Frequency
|Accurate, low-cost clock and frequency generation based on satellite positioning technology
In addition to positioning and navigation applications, GPS/GNSS signals are widely used as low-cost precision time or frequency references used by remote or distributed wireless communication, industrial, financial, and power-distribution equipment. By capitalizing on atomic clocks which are onboard positioning satellites, GPS/GNSS signals which contain embedded timing information can be used to synchronise equipment to within 15 ns, as well as provide UTC time to an accuracy within 90 ns. For wireless communication standards that utilize Time Division Multiplex (TDM) and for CDMA2000 in applications such as femtocell basestations, a precision time reference is mandatory. For these and other systems, GPS/GNSS signals are utilized to provide an accurate reference frequency to within 1 part in 100 billion (1011).
u-blox’ range of precision timing chips and modules are able to fulfill this important reference function for a fraction of the cost, power consumption, maintenance, size and weight of other technologies with comparable performance. The stand-alone products provide accurate time pulses wherever GPS/GNSS signals are available, as well as precise disciplined frequency references with hold-over.
