GPS Programs Push Ahead

The GPS program continues progress on several fronts — in space and on the ground.

During fall 2010, the U.S. Air Force and the Raytheon Company team developing the GPS Advanced Control Segment (OCX) successfully carried out an integrated baseline review (IBR) for the next-generation system on schedule.

When completed in 2015 under the current schedule, GPS OCX will deliver control segment enhancements designed to provide secure, accurate and reliable navigation and timing information to military, commercial and civil users.

GMV Will Launch Fully Hosted Software GPS Receiver at Mobile World Congress

GMV will launch the SRX-10, a software GPS receiver for mass-market applications, at this year’s GSMA Mobile World Congress, scheduled February 14–17 in Barcelona, Spain.

As a fully hosted solution, all SRX-10 receiver functions — even signal acquisition and tracking — can be hosted on a general purpose CPU with only the requirement of adding on a low cost RF front-end, according to the company.
The company cites other benefits offered by its new software receiver, particularly its substantial flexibility and upgradeability.

Tracking Santa and Father Frost: GPS or GLONASS

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

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

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.
