White Papers: What Time is it? It’s a Matter of Trust Those in the business of measuring time are familiar with the saying, “If you have one clock, you know what time it is. If you have two, well…”. Time synchronization is the ability for all clocks to have the same time. But what time is it? If your time synchronization deployment uses time from the internet, your organization may be at risk. Official time provided by a GPS-based network appliance is a time source that you can trust. pdf - 399 KB

Technical Notes and Briefs: Changes in the WWVB Radio Signal Affects Precision Frequency and Timing Reference

Spectracom had used the WWVB signal to synchronize its time and frequency references and master clocks in North America before the wide-spread use of GPS for precision timing applications. The last of these WWVB products has not been promoted for over 10 years and officially went end-of-life in 2005. A change in the WWVB signal was being considered in recent years to reduce impact of electro-magnetic interference and allowing for improved reception in consumer-grade clocks and watches1. However, this change affects the operation of precise time and frequency standards whose receivers are based on phase-locked loops, such as Spectracom WWVB receivers, so these products will no longer operate as intended.

Presentations and Articles: Zone Based Indoor Location Using GNSS Simulators Signals from Global Navigation Satellite Systems (GNSS), such as the Global Positioning System (GPS), are very weak and usually cannot be seen indoors or underground. A common method to overcome the problem of receiving GNSS signals indoors or underground is to use a GPS/GNSS repeater with an antenna located outdoors to receive the GNSS signals and an amplifier/antenna to re-transmit the signal indoors. This paper describes the technologies and methods for creating an intelligent repeater system including time synchronization at the nanosecond, microsecond, and millisecond levels, how each synchronization level affects the overall system and methods for achieving each, power level considerations including power level requirements between zones and how they affect transitions from one zone to another, data transfer and example system configurations. While GPS is primarily demonstrated and tested, the possibility for adding other GNSS constellations such as QZSS, BeiDou, Galileo, and GLONASS are also presented. pdf - 270 KB
