What is STL?

GNSS systems do a good job providing solutions for diverse applications, but they were never designed to be used in many of the ways applied today. Satellite Time and Location Signal Technology (STL) has features that complement GPS and other GNSS satellite signals, enabling more robust system designs.

Master Clock Systems

Master Clocks normally take one or more precise timing reference signals as inputs, then convert and distribute those timing references to other devices so their clocks are almost as accurate as the master clock.

GPS Clock Synchronization

Electronic clocks control critical functions in many applications. However, clocks are often designed for low cost rather than for keeping accurate time.

IRIG Timecode Synchronization

IRIG timecodes are a set of standard specifications originally developed by the Inter-Range Instrumentation Group to transmit very precise time via a pulse rate.

While GPS is an indispensable tool for synchronizing military networks and navigating military vehicles, it is vulnerable to jamming and spoofing.

What is a GPS Simulator?

As GPS receivers are built into more mission-critical devices for difficult application environments, developers and manufacturers need better ways to guarantee performance.

What is a Leap Second?

When a irregularities caused by drifting in the Earth's rotation create a gap between Coordinated Universal Time (UTC) and the mean solar time, a leap second is inserted in the UTC time scale to keep it in step with the solar day.
