White Papers: Time for Data Centers to Consider Time as a Service	Time for Data Centers to Consider Time as a Service If you are in the data center business, you’re faced with a long list of customer demands as businesses and entire industries move operations to the cloud. But you’re also facing an increasingly competitive landscape where offering the best service and greatest value is paramount. Balancing what you can offer customers and at what cost can be complicated, to say the least. An often overlooked service offering, one which provides a large value to customers at a low cost to providers, is Time as a Service (TaaS).	pdf - 472 KB Tuesday, April 21, 2015 [ Permalink ]
White Papers: Beyond GPS: A Multilayered Approach to Addressing PNT Vulnerabilities	Beyond GPS: A Multilayered Approach to Addressing PNT Vulnerabilities The Global Positioning System is fundamental to the strength of American fighting forces. But GPS is vulnerable. One European Union study detected nearly 500,000 interference events in 23 countries from 2016 to 2019. This white paper discusses options for deploying a range of interlocking and overlapping solutions. In this multilayered vision, existing and emerging technologies can be used to minimize threats.

White Papers: A Master Clock Approach to Distributing Precision Time and Frequency	A Master Clock Approach to Distributing Precision Time and Frequency Traditional time and frequency distribution is defined by splitting and amplifying a signal to as many devices as needed. The distribution amplifier became a mainstay in precision time and frequency systems. Today there is greater access to precision timing considering more clocks in space transmitting global navigation signals and more network connectivity able to maintain higher levels of timing accuracy. A new generation of master clocks is capable of leveraging these trends while offering flexibility to generate the signal types and quantities wherever needed. Distribution amplifiers can still be an important “brick” in the system to meet needs for redundancy, reliability and cost-efficiency. This white paper describes the issue of providing precise time and frequency signals of the type and quantity needed by the application using commercial-off-the-shelf devices from Spectracom.	pdf - 652 KB Friday, January 31, 2014 [ Permalink ]

White Papers: What Time is it? It’s a Matter of Trust	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 Friday, September 5, 2014 [ Permalink ]
