** The ARRL put officials in Manassas, Virginia, on notice that the League
will act on behalf of its members to ensure full compliance with FCC
regulations when the city's Broadband over Power Line (BPL) system starts up
in a few months. The League was responding to media reports that Manassas--a
Washington, DC, suburb--has approved plans for a citywide BPL rollout.
Manassas City Council reportedly voted unanimously October 16 to grant a
10-year franchise to Prospect Street Broadband to expand a BPL field trial
and offer high-speed Internet service to the entire community over municipal
power lines. --ARRL
** Two Japanese satellites have been in trouble following geomagnetic
storms triggered by recent solar flares, one of them the largest in three
decades, the Japanese space agency said Thursday. ADEOS-2, one of the
world's biggest earth observation satellites, has lost contact with the
earth since last Saturday due to a possible glitch in its electrical system,
a spokesman for the Japan Aerospace Exploration Agency said. The
communications satellite Kodama has stopped relaying data after its sensor
developed trouble early Wednesday after the massive flare, Junichi Moriuma
added. --SpaceDaily
** The Voyager journey of discovery continues. After traveling through
space for more than 26 years, voyager 1 is approaching a new milestone. On
November 5, 2003, the spacecraft will be 90 astronomical units (AU) from the
Sun. 90 AU is the equivalent of about 8.4 billion miles or 13.5 billion
kilometers. Recent observations indicate that Voyager 1 is in a region
unlike any encounter in its 26 years of exploration. These observations and
what they may infer about the approach to the termination shock will be the
subject of a NASA Space Science Update (SSU) on November 5, 2003. The SSU
will be carried live on NASA Select beginning at 1:00 PM EST. --SpaceDaily
** Penn State engineers have developed innovative design methods for a new
class of antennas composed of an array of fractal-shaped tiles that offer
anywhere from a 4:1 to 8:1 improvement in bandwidth compared to their
conventional counterparts. The new broadband antennas are composed of
irregular but self-similar, repeated fractal-shaped unit tiles or
"fractiles" which cover an entire plane without any gaps or overlaps. While
fractal concepts have been used previously in antenna design, Werner and his
research team are the first to introduce a design approach for broadband
phased array antenna systems that combines aspects of tiling theory with
fractal geometry. --SpaceDaily
