Photo: Jackson Labs Jackson Labs Technologies (JTL) has launched the PNT-6220 Assured Reference — a product combining low-Earth-orbit (LEO) signals, GNSS, terrestrial, wireline and atomic clock services in one small solution, specifically designed for critical infrastructure applications. The PNT-6220 reference seamlessly combines concurrent L1, L2, L3 and L5 GNSS reception with a custom JLT-designed LEO-based Satellite Time and Location (STL) timing receiver. It also includes terrestrial receivers and PTP/IEEE-1588 edge grandmaster (EGM) and PTP/IEEE-1588-slave capability. The PNT-6220 provides assured PNT for critical infrastructure applications such as those described in the directives of Presidential Executive Order 13905. It can serve as a timing reference for 5G equipment, an ePRTC-capable reference, or a high-performance disciplined reference that supports PTP/IEEE-1588, STL, RF distribution and multi-frequency GNSS capability. The PNT-6220 will be able to select the most optimal UTC reference input automatically and auto-switchover among its numerous reference inputs if one or more of them are jammed or spoofed, as well as average several references for additional stability and accuracy. If all external references are jammed, the unit can provide UTC timing from its internal holdover oscillator with options that have less than 100-ns drift over 24 hours. The unit is also capable of outputting a GPS RF distribution signal driven by the internal flywheel oscillator, which allows glue-less retrofitting of any GPS-based legacy user equipment to the state-of-the-art reference sources the PNT-6220 can receive by simply plugging into the legacy equipment GPS antenna input. Available Options Numerous options are available for the half-width 19-inch-wide rack-mount box.
