Qinetiq, Rockwell Demonstrate Multi-Constellation Galileo/GPS Secure Positioning for Governmental Applications

November 12, 2013By

On August 30, QinetiQ and Rockwell Collins demonstrated the first joint satellite navigation positioning using live signals from the encrypted governmental services from the U.S. Department of Defense (DOD) GPS Precise Positioning Service (GPS-PPS) and the new European Galileo Public Regulated Service (PRS). The signals on GPS L1 and L2, together with Galileo PRS L1A and E6A, were processed and... read more

New Structure for GLONASS Nav Message

November 2, 2013By
Glonass-K-W

Russian scientists propose a new code-division multiple-access signal format to be broadcast on a new GLONASS L3 signal. Once implemented across the modernizing GLONASS constellation, this will facilitate interoperability with — and eventually interchangeability among — other GNSS signals. The flexible message format permits relatively easy upgrades in the navigation message, if required. read more

Delta IV, the current GPS launch vehicle, awaits a date with space at Cape Canaveral.

Launch Delays Ground GPS IIF and Galileo FOC The scheduled October 23 launch of GPS IIF-5, the fifth in the current “follow-on” generation of GPS satellites, has been postponed in order to complete a review of an adjustment made to the rocket’s upper stage engine. A loss of thrust by a Delta IV rocket upper stage during a GPS launch last... read more

The Halloween Storms: When Solar Events Spooked the Skies

October 30, 2013By
ssn_predict_l-O

Ten years ago, scientists watching the skies experienced a Halloween fright of cosmic proportions, when space weather degraded GPS signals, affecting land and ocean surveys, and commercial and military aircraft navigation. The most extreme of what became known as the Halloween Storms hit on October 30, 2003 — ten years ago today. According to the National Oceanic and Atmospheric Agency,... read more
