SEL has released a new network clock designed for critical infrastructure and harsh environments. Model SEL-2488 receives GNSS time signals and distributes precise time via multiple output protocols, including IRIG-B and NTP. The SEL-2488 provides time-delay compensation for antenna cables and output cables on per-port basis to further optimize time distribution accuracy. For security, the clock features the Syslog Ethernet standard... read more

The fifth and sixth Galileo satellites have been in a safe state since August 28, under control from ESA’s center in Darmstadt, Germany, despite having been released on August 22 into lower and elliptical orbits instead of the expected circular orbits. The European Space Agency has released two diagrams showing the orbits. ESA said that the potential of exploiting the... read more
Following the July launch of Explorer for ArcGIS on Mac OS X, the Explorer team released an update into the app store today that broadens the reach of Explorer by adding support for 21 new languages. Explorer for ArcGIS is now available in all of the country app stores supported by the Mac App Store. It can be downloaded from... read more
Spirent Federal Systems, a U.S. provider of positioning, navigation and timing test solutions to the government and its contractors, announces that its GSS9000 RF constellation simulator has been reviewed and granted security approval by the GPS Directorate. Higher dynamic simulations with more accuracy and fidelity are enabled by 1000-Hz (1 ms) System Iteration Rate — a four-fold increase over Spirent’s current GSS8000 product — zero inter-channel bias... read more
Rockwell Collins has successfully received and tracked a Galileo satellite signal using a prototype GNSS receiver designed for secure military use. In 2013, Rockwell Collins received a $2 million contract from the Air Force Research Laboratory (AFRL) and the GPS Directorate to develop and demonstrate a Secure Software Defined Radio (S-SDR) GNSS receiver capability. By using multiple available satellite signals, improved and more... read more
