Common Struggles of Data Center Operators

Engineering and operations personnel responsible for designing and running today’s most modern and sophisticated data centers are aware that things can go wrong without proper timing synchronization. Some typical examples:
Network Time Protocol (NTP) frequently fails to deliver the accuracy needed for today’s time-sensitive applications.

Precision Time Protocol (PTP) offers better accuracy than NTP but relying on PTP to provide time to distant applications and appliances at the network edge too often introduces an accumulated timing error.

Using GPS/GNSS as a source of time is challenging within indoor locations where the signal has a hard time reaching without outdoor antennas that are difficult and expensive to install and maintain.

Having a backup source of time is essential. However, establishing redundant GPS/GNSS sources is burdensome and expensive — and it usually fails to deliver true resilience.
If these problems sound familiar, then it’s time to consider a timing solution from Satelles. STL is easy to connect and simple to configure, it operates indoors and in occluded environments, and it just works.

Our History

Satelles traces its origins to a team of four Ph.D. graduates from Stanford, all of whom were protégés of Professor Brad Parkinson, the ‘father of GPS’, and Professor Per Enge. These scientists and engineers had already pioneered GPS-based agricultural guidance systems and autonomous aviation platforms when they set their sights on innovating a new form of positioning, navigation, and timing with the purpose of backing up and augmenting GPS. They founded Satelles as a business in 2013, and the Satellite Time and Location (STL) service has been operationally available since 2016. Since then, the company has deployed STL to customers around the world.

Did you know?

Inauthentic GNSS signals are responsible for several incidents of lawlessness on the high seas. The New York Times published an article in September 2022 about ships that are faking their GNSS coordinates to evade Western sanctions on Russia. Shipping data researchers have identified hundreds of cases where a ship has transmitted fake location coordinates to carry out illegal business operations and circumvent international laws and sanctions.

However, GPS and GNSS have some inherent vulnerabilities —
and are open to serious threats.

Lack of Strength

The GPS signal is essentially a “whisper” from satellites orbiting at an altitude of 12,500 miles. As such, the GPS signal is not that strong and not available everywhere.

Susceptible to Degradation

GPS is vulnerable to signal degradation by buildings, tunnels, tree canopies, and other obstructions. This creates a problem for PNT-dependent systems that are indoors or in other locations where GPS cannot easily reach.
