EndRun Technologies, a provider of precision time and frequency solutions, announced at the Precision Time and Time Interval Systems and Applications (PTTI) meeting the release of the RTM3205 precision timing module for portable time and frequency applications. The PTTI meeting is being held Jan. 30-Feb. 2 in Monterey, California. The RTM3205 precision timing module by EndRun Technologies. Photo: EndRun The second-generation RTM3205 is optimized for size, weight, and power (SWaP), but can exceed the stability of a standard cesium atomic frequency reference. The GPS-synchronized RTM3205 is based on EndRun’s Meridian II precision timebase instrument providing a subset of outputs with the same accuracy, stability and ultra-low phase noise. For ultimate performance, EndRun’s innovative real-time ionospheric corrections are available to directly measure and compensate for the ionospheric delay of received GPS signals in real time. The network-centric RTM3205 provides a dual-gigabit Ethernet interface supporting a high-bandwidth Stratum 1 Network Time Protocol (NTP) server, optional IEEE 1588 — Precision Time Protocol (PTP) grandmaster, and secure management. “The versatile RTM3205 precision timing module is a consolidation of EndRun’s state-of-the-art time and frequency technologies in a small, thermal efficient module.” said Michael Korreng, senior R&D engineer, EndRun Technologies. “Customers can now easily integrate this high-performance, time and frequency module into portable and tactical systems.” Key RTM3205 performance specifications with Real-time Ionospheric Corrections and an Ultra-Stable OCXO are: Time accuracy of Frequency accuracy better than 4×10-14 (1 day average) Short-term stability -13 at 1 second Ultra-low phase noise 10 MHz ( Dual-gigabit Ethernet with a Stratum 1 NTP server (7500 packets per second) IEEE 1588 PTP grandmaster option Low power, The RTM3205 is available now.
