GNSS satellites are equipped with atomic clocks that are accurate to within nanoseconds. While this incredibly accurate time measurement is necessary for the calculation of GNSS positioning, GNSS receivers can also use this to provide timing accuracies of better than 20 ns. This accurate timing source can be utilized for a wide range of other applications. Take seismic monitoring for example. The epicenter of an earthquake can be precisely determined by using seismic monitors that have been synchronized with GNSS satellite clocks. By knowing the exact time the earthquake was detected at various locations, the place of origin can be readily calculated.
In addition to scientific research, businesses utilize time information to gain efficiencies in how they manage workflows and data. Synchronization of communications systems, electrical power grids and financial networks ensures systems are maximizing their capabilities.
