GLONASS Triple Satellite Launch Suffers Rare Failure

A Proton rocket carrying three modernized GLONASS (GLONASS-M) satellites failed to reach orbit following its launch Sunday (December 5, 2010), falling into the Pacific Ocean.

The Russian Federal Space Agency (Roscosmos) said that a special board had been established to investigate the event — rare for the GLONASS program — and "define next steps."

Tracking Santa and Father Frost: GPS or GLONASS

GLONASS Tracks Father Frost

As GLONASS approaches completion, it’s no surprise that the Russian counterpart to GPS has gotten into more popular applications of GNSS technology — even Santa-tracking.

For more than 50 years, the North American Air Defense Command (NORAD) has followed the travels of the Christmas gift-bearer from his North Pole headquarters. The Santa-tracking operation can be viewed online.

GPS Satellite Number 23 is 20 Years Old – And Counting

(From top) GPS Block I, Block IA, Block II, Block IIA

A 20-year-old GPS Block IIA satellite designated as space vehicle number 23 (SVN23) is setting new records in longevity among the durable spacecraft of the Global Positioning System.

Built by Boeing (formerly Rockwell Corporation) and launched on November 26, 1990, SVN23 has operated longer than any other GPS satellites — far exceeding its design life of 7.5 years.  Set healthy shortly after launch for navigation and timing use, the GPS Directorate (formerly GPS Wing) at Los Angeles Air Force Base predicts that the satellite will last another 12–18 months.

United States Appeals Courts Disagree on GPS Technology and Privacy Rights

District of Columbia Court of Appeals in Washington D.C., USA

Secret tracking using GPS may be simple, undetectable and cheap — but appeals courts can’t decide if it’s constitutional.

In 1791, when the Fourth Amendment to the United States Constitution was ratified, it certainly seemed specific enough for the needs of the time. The new Americans were tired of colonial powers freely searching and seizing, with general warrants that were as full of holes as Swiss cheese.

Goodbye, GPS Wing; Hello, GPS Directorate

The U.S. Air Force will inactivate its GPS Wing at Los Angeles Air Force Base on Wednesday (November 10) and replace it with the Global Positioning Systems Directorate.

Reflecting mostly the taxonomy and naming conventions of military commands and organization, the new designation is expected to bring little change in the new organization’s leadership or scope of responsibilities, although the organization will no longer have headquarters status. Air Force Groups will become Divisions and Squadrons, Branches.
