Three More GLONASS Satellites Come On-Line

Russia’s space forces had an easier time of it bringing the latest set of GLONASS-M satellites on line within just over a month after launch.

As of December 6, the GLONASS constellation had 15 operational satellites, two of which are not broadcasting signals during maintenance. The next launch of three modernized GLONASS space vehicles is scheduled for December 25.

GNSS Believer

Technology-agnostic. Now there’s an interesting term.

I first heard it from engineering staff at the Federal Communications Commission as they backpedaled away from a premature assumption that network-based solutions would meet the agency’s E911 mandate for wireless phones. After, that is, their assumption was confronted with a more accurate, more far-reaching GPS technology.

Platforms for a Future GNSS Receiver

GNSS receiver technology has changed dramatically since the first reception of a GPS signal. It evolved from complex electrical circuits — partly analog — tracking only one satellite at a time to today’s sophisticated, small multichannel receivers. The core of a modern receiver is contained in one or more highly sophisticated chips that perform all the receiver’s tasks, starting with signal processing, followed by positioning, and often ending at application processing.

Russia Places 3 GLONASS Satellites in Orbit

Russia successfully launched three modernized GLONASS (GLONASS-M) satellites from the Baikonur Cosmodrome in Kazakhstan on October 26, a day later than planned due to a Kazakh national holiday. The Proton-K rocket, equipped with a Block DM upper stage and carrying three Uragan-M (GLONASS-M No. 18, 19, 20) satellites, lifted off at 11:35 Moscow time.

GNSS for the Masses

Oh, yes, to be sure — they are really impressive numbers: the steep upward curve of unit and dollar (or euro or ruble or renminbi) sales volumes now that GNSS has hit the big time.

Whether it’s $25 billion today or $68 billion in 2010, the worldwide market has really taken off since consumers have discovered — almost by accident, in many cases — the amazing power of GNSS-driven products and services.

Ah, consumers. The mass market.

Rich! We’ll all be rich beyond our wildest imaginings!

GLONASS Launch Is Back On for October 25

Investigation into a Proton-M rocket failure in September, which appeared to threaten the schedule for continued rebuilding of the GLONASS constellation, has cleared the launcher and Baikonur facility for renewed activity, including a scheduled October 25 launch of three GLONASS-M satellites.

Get ready for the 2008 Toulouse Space Show! ENC-GNSS, EFTF 08, and more . . .

Next April’s Toulouse Space Show will provide a good deal of company for the European Navigation Conference (ENC-GNSS 2008).

In addition to the annual European Frequency and Time Forum (EFTF 08), which joined ENC-GNSS 2007 this year at TimeNav '07 in Geneva, Switzerland, events include a Space Applications symposium sponsored by the French space agency CNES, a commercial exhibition, and associated events for the general public, students, and young people, to promote the value of space applications in daily life.
