Statum 1 Time Server

How Does GPS Network Time Synchronization Work?

Whether you're trying to get people to show up for a meeting or managing a scalable cloud-based business application, synchronicity is vital. Countless stakeholders and machines play essential roles in your processes. Keeping them all on the same timetable lets your organization move forward as a cohesive unit.

As far as networked hardware is concerned, you can't afford timing disparities. Here's how network time synchronization works and how to make your practices more effective.

Are You Ready for the Next GPS Week Number Rollover?

Click here to read the Department of Homeland Security’s memorandum about the upcoming Global Positioning System Week Number Rollover Event.

Do your networks or systems use Coordinated Universal Time, or UTC? April 6, 2019, is probably a date worth marking in advance. Unlike a regular calendar event or holiday, this day will mark a special rollover of the GPS week number, or WN, that helps receivers tell time more precisely.  

The only question is whether your devices will react to the rollover event properly. Here's what you should know. 

Network Synchronization: Internet NTP Servers vs. GPS NTP Servers


Measuring time is about more than merely knowing when events occur. It's a vital prerequisite for synchronizing your operations, securing your data and serving your clientele. It pays to be precise, accurate and on-time, and your ability to do so depends on how good your time server is.

Unfortunately, you're unsure which kind of time server is best. You've narrowed it down to two choices: internet-based NTP and GPS-referenced Stratum 1 NTP. The distinctions aren't so clear, but these facts might make it easier to pick wisely.

Network Timekeeping: NTP vs. SNTP

In the world of modern computing, accurate timing is everything. As networks grow increasingly complicated, they demand reliable standards that ensure everything is running on the same unified schedule.NTP, or Network Time Protocol, is a standard method for synchronizing different computer clocks. Here's how it compares to SNTP, or Simple Network Time Protocol.

FINRA Clock Synchronization Regulations - Are You in Compliance?

In April 2016, the Securities and Exchange Commission approved a proposed rule change from the Financial Industry Regulatory Authority to tighten rules for clock synchronization at National Market System securities and over-the-counter equity securities firms. It's important for these companies to understand the changes and to have the right Network Time Protocol servers to maintain compliance. Firms have until Feb. 20, 2017 to comply.

Accurate Time Stamping for Video Surveillance

Through the use of a Stratum 1 NTP server, it is possible to produce surveillance videos with timestamps legally-traceable to UTC. This solution is far more cost-effective and accurate than others, and has quickly become the preferred option for video surveillance applications.

A GPS NTP server synchronizes to precise time from GPS satellites and operates securely behind a firewall to synchronize all elements of a system, down to the millisecond. Indeed, such servers typically have a margin of error of just plus or minus two milliseconds, which is more than accurate enough for successfully defending time-stamped evidence in a court of law.
