DS-VGPS-CLOCKGPS clock provider and GNSS receiver The DS-GPS-CLOCK uses a 10 Hz GNSS sensor and can be used for simple positioning measurement applications as well as for synchronization of Dewesoft data acquisition systems. The DS-GPS-CLOCK is a synchronized time base generator capable of using either GPS or IRIG as a time source. This allows completely synchronized data acquisition of multiple systems whether they are mobile or stationary. Additionally, the DS-GPS-CLOCK can also be used as an IRIG time code generator (output IRIG B/DC) synchronized to the GPS time. The base of any GPS receiver is precise time measurement. In addition to the position information, a precise PPS (pulse per second) is generated by the GPS engine. This pulse is used to synchronize a 40 MHz oscillator with software PLL (phase-locked loop). The result is an ultra-stable 40 MHz clock source that is completely free of drift over time. |
