MEMS and Platform Orientation & Deep Integration of GNSS/Inertial Systems

Q: How can a GPS receiver or MEMS (micro-electro-mechanical systems) inertial sensor assembly sense a host platform’s orientation? How can these sensor technologies be combined together?

Russia Stays on Schedule with Latest GLONASS Launch

Launch of three GLONASS satellites on December 25 has met the terms and schedule of a presidential initiative to have 18 of the Russian GNSS space vehicles (SVs) on orbit and operational by the end of 2007.

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!
