RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

September 14, 2016 - Smiths Microwave Subsystems is pleased to announce that TRAK has released the 8836 series tactical GPS Time and Frequency System. The design approach integrates a ground-based GPS receiver module (GB-GRAM), a rubidium oscillator, time and frequency signal generation, and control/status circuitry in a compact, ruggedized enclosure.
Standard outputs include 1PPS, low noise 10 MHz Network Time Protocol (NTP) and two IRIG B outputs over multi-mode fiber. The 8836 can be synchronized from the internal GPS receiver or from an external GPS 1PPS. When tracking GPS with a TFOM of 3 or better, the discipline algorithm steers the internal oscillator providing 1 PPS time accuracy of < 30 nS to UTC and long term frequency stability of < 1E-12 averaged over 24 hours. In the absence of GPS the unit transitions into hold-over mode providing an accumulated time drift of < ± 2 μS in 24 hours. An Ethernet interface provides NTP, SNMP v1, v2 and v3, SSH, syslog and telnet. Three GPS Standard Serial Interface Protocol (GSSIP) ports are provided from the GB-GRAM. Two ports are configured to automatically output ICD-GPS-153 messages and the third port is configured to output NMEA-0183 messages. For more information, visit www.TRAK.com
