Russia launched a single GLONASS-M satellite into orbit on Monday (November 28, 2011) from the Plesetsk space center north of Moscow.
This is the fifth and the last launch of a GLONASS satellite this year, according to the Russian Federal Space Agency.
Typically, Russia launches three of the modernized satellites at a time on Proton rockets, including three GLONASS-Ms sent up November 4 from Baikonur, Kazahkstan, and placed in orbital plane 1. Monday’s launch used the smaller Soyuz rocket to place the satellite into plane 3.

No sooner had GPS positioning helped validate key aspects of Einstein’s general theory of relativity in the Gravity Probe-B program than GPS timing has been cited as helping bring his special theory of relativity into doubt.
At issue is the so-called OPERA (Oscillation Project with Emulsion-tRacking Apparatus) experiment, inaugurated in 2006 with the main goal of studying the rare transformation (oscillation) of muon neutrinos into tau neutrinos.

Although a Department of Homeland Security (DHS) report on the risks posed by GPS disruptions has yet to be released, the analysis has inspired a proposal to create receivers capable of self-diagnosing spoofing attempts.
“The receiver is the first line of defense,” Logan Scott, president of LS Consulting, told members of the National Space-based Positioning, Navigation, and Timing (PNT) Advisory Board this week.
