GNSS Vulnerabilities and Solutions Conference 2009

The 2009 GNSS conference will focus on problems and vulnerabilities, and in particular, on developments aiming to improve the accuracy and reliability of the various GNSSes. It will take place on the resort island of Krk during the Adriatic high season.

Two special sessions will be organised in order to address particular causes of GNSS vulnerabilities: Space Weather and Ionospheric Effects on GNSS, and Safety Critical Applications (concerning primarily the ITS).

GPS-Monitored Vehicle Fees: Change You Can’t Believe In

Transportation Secretary Ray LaHood

One change that apparently won’t happen under the Obama administration is replacing the federal gasoline tax with a GPS-monitored mileage fee.

In an interview with the Associated Press last week, U.S. Department of Transportation (DoT) Secretary Ray LaHood had suggested that his agency should look at a “vehicular miles program where people are actually clocked on the number of miles that they traveled.”

It was one of the shortest flights of a trial balloon so far this year.

CSR-SiRF Merger Pairs Struggling Bluetooth and GPS Powerhouses - and Shows Handset Platform Dominance

CSR-SiRF Merger Pairs Struggling Bluetooth and GPS Powerhouses – and Shows Handset Platform Dominance

CSR image

Merger plans recently announced by CSR (Cambridge Silicon Radio) plc and SiRF Technology Inc. connote more than the evolving fortunes and common future of a Cambridge, UK–based Bluetooth and WiFi provider and a San Jose, California GPS manufacturer.

It reaffirms the emergence of mobile phone handsets as a dominant location platform, the convergence of wireless communications and positioning at the chip level, and the trend toward absorption by semiconductor manufacturers of independent GPS technology providers who offer only single-frequency solutions.

Satellite Collision Raises Issue of Similar GNSS Risks

Satellite Collision Raises Issue of Similar GNSS Risks

GPS Orbital Decay. Aerospace Corporation

The February 10 collision of an active Iridium satellite and a defunct Russian military communications satellite underlines a concern raised recently at the International Committee on GNSS (ICG) about the need to include coordination of space vehicle (SV) operations.

In comments during a session of Working Group A (compatibility and interoperability) during the ICG’s recent meeting in Pasadena, California, Professor Grigory Stupak of the Russian Institute for Space Device Engineering (RISDE), noted that Russia’s “position is that compatibility includes more than just signals,” among other things, “the sharing of orbits and disposal of satellites.”

Similar concerns have been expressed in recent years by organizations that have studied the possibility of GNSS satellites, particularly those that have been “parked” in disposal or graveyard orbits, to drift and possibly collide with one another.

New Russian GLONASS Satellites in Operation

New Russian GLONASS Satellites in Operation

The last of three GLONASS satellites launched December 25 began broadcasting a healthy navigation signal today (February 12), according to the Russian Space Agency’s Information-Analytical Center, bringing Russia’s operational GNSS constellation to 20 spacecraft.

One satellite, space vehicle number (SVN) 701 launched more than five years ago, has been off-line and in “maintenance” status for the last month. Another spacecraft, SVN 722, is transmitting only in the GLONASS L1 band.
