PCTEL GPS antennas in GAGAN
PCTEL will deploy its WAAS ground
station GPS antennas in India's GPS-Aided
Geosynchronous Augmented Navigation
(GAGAN) system. These antennas are
currently deployed for the North American
WAAS system and Japan's MSAS. The
land-based WAAS antennas enable
highly precise navigation and tracking of
aircraft and covers L1, L2, and L5 GPS
frequencies.http://investor.pctel.com
GLONASS-M Satellites head to pad
The Russian Reshetnev Company has
sent the fi rst of three GLONASS-Ms
satellites to the Baikonur spacedrome and
launch pad in Kazakhstan. A second set
of three Glonass-M are to be launched
in December, thus providing 6 more
satellites to enlarge the constellation.
Barring further on-orbit failures, this could
yield 99.97 percent global availability
of three-dimensional positioning -
effectively full operational capability
(FOC) status - earlier than the planned
date, end of 2010. Another two group
launches in 2010, of three GLONASS-M
satellites in September and two M and
one K in December, would achieve FOC
of 24 spacecraft. http://en.rian.ru
GPS IIR-21(M) Satellite operational
The last in the series of eight modernized
GPS IIR satellites, GPS IIR-21(M),
was declared operational for military
and civilian users worldwide. GPS IIR-
21(M) will join the constellation of 30
operational satellites on orbit providing
global coverage and increased overall
performance of GPS service. This
IIR-M satellite provides improved
accuracy, enhanced encryption, antijamming
capabilities, and a second
civil signal to provide dual frequency
capability and improve resistance to
interference. www.losangeles.af.mil
PRN01/SVN49: GPS Satellite anomaly
From monitoring at the University of
New Brunswick and elsewhere around
the globe, it appears that normal signals
from the L1 and L2 transmitters on
the GPS satellite PRN01/SVN49 were
unavailable for more than two hours on
the morning of September 4 from about
12:00 to 14:11 UTC. The L5 test signal
continued to be tracked by some receivers
but not others. http://sci.tech-archive.net
PerkinElmer contract for Next
Generation GPS
PerkinElmer, Inc. has been awarded
a contract for $15 million from ITT
Corporation Space Systems Division to
support the GPS Block IIIA Space System
program. It will design and implement
several engineering advances into its
heritage GPS Block IIR and Block IIF
RAFS, as well as qualify and deliver fl ight
units for the fi rst two satellite vehicles by
March 2012. Lockheed Martin, operating
under an initial $1.4B contract, is the
program's Space System prime contractor
for this next-generation system, and
ITT is the provider for the cutting-edge
technology navigation payload designed
to provide improved position, navigation
and timing services. www.perkinelmer.com
Partnership to fi nd missing children
MapQuest and the National Centre for
Missing & Exploited Children® (NCMEC)
launched a new widget on MapQuest
Local that includes valuable missing child
alerts and information from NCMEC.
It features pictures and information
about children who are missing from the
geographic area for which the MapQuest
Local page is set. Also included is the
ability to search for missing children
by name and link directly to NCMEC's
homepage. www.mapquest.com
Web maps from Ericsson Labs
Ericsson Labs have launched Ericsson
Web Maps with APIs, web components
and documentation to enable developers
to bring dynamic maps into web sites or
web applications. It uses Idevio's patented
map technology RaveGeo to distribute
and visualise the map. www.ericsson.com
