GNSS: What next?
F Michael Swiek, Miguel Angel Martínez Olagüe, Bruce Peetz, Keith D McDonald, Bernhard Richter,Sang Jeong Lee, Ir. Hans Visser, John Pottle, Thomas Seiler, |
It is a fascinating time for GNSS. The US is set to modernize GPS and Russia is making steady progress on GLOSNASS. Despite the intricacies involved, Europe is determined to realize Galileo. Not surprisingly, the industry is introducing imaginative and innovative applications built around these technologies. The technology providers face the additional challence of meeting the evolving needs of the users. We asked Mr Mike Sweik, Executive Director, US GPS Industry Council, to moderate the discussion. |

| DGPS reference
network |

GPS In 2008 GPS remains dominant with
32 nominal Satellites. At the same time
local DOP holes will remain possible as
the aging GPS constellation may have
multiple unhealthy satellites. Standard
GPS L1 accuracy improvement will slowly
start degrading as the Ionospheric activity
will increase to the next solar max in 2012.
SBAS In Europe EGNOS is maturing
and will finally achieve it’s in orbit
validation (IOV). Working towards QZSS
and Gagan will continue to operate.
Glonass Glonass will again launch 6
satellites in 2008, but at the same time the older generation of Satellites will
become unhealthy leaving a 12 Glonass
Satellites constellation at year’s end.
Omnistar Omnistar will replace in
2008 most of its 100 reference stations
with new Glonass capable reference
stations. Omnistar will expand the
DGPS reference network into new
areas as India, Kazakhstan and China.
Omnistar will in 2008 improve
the broadcasting data format to be
more compressed and allow more
measurement data to be sent over the
12 worldwide satellite links. Omnistar
HP converge time will again improve.
Also in 2008 Omnistar’s worldwide
10 cm accuracy system will improve
gradually. Omnistar will add three
new geostationary L-band correction
satellites in America (AORW), Europe
(AORE) and Asia (IOR). Omnistar
corrections over cellular phone
will start with pilot projects.

| Industry
consolidation |
John Pottle
Director of Spirent Communications |
Everywhere one looks, there is evidence
that GNSS is hitting the mainstream.
New signals, new applications, new lower
prices, better maps, more accuracy…
everything points to the acceleration of
the navigation and positioning revolution.
In 2008, we are looking forward to:
Galileo will the Galileo project forge
ahead in 2008 or be tarnished by some
of the organisation and funding issues
that we have all read about recently? My
prediction is that 2008 will be a good year
for Galileo. Confidence will build and
developers will start to seriously look at
adding Galileo compatibility to receivers.
Compass the industry is hungry for
more information about the intriguing
Compass system. Perhaps it will become
available during 2008? The Chinese
have indicated their intention to make
information available on the open
Compass signal(s), something we all look
forward to understanding more about.
GLONAS more launches recently,
with more in prospect, and the
potential for CDMA technology in
future, make GLONASS a serious
GNSS that is receiving increasing
interest already. This looks set
to continue through 2008.
Industry consolidation is likely to
continue. Of particular note already
are the emergence of Broadcomm
(with the Global Locate deal) and
Cambridge Silicon Radio (with the
CPS and NordNav deals). A-GPS
location applications growth: we have
been waiting for cellphone-based
location applications for many years.
With a few exceptions (eg. Korea,
Japan) we are still waiting. 2008 could
be the year that this will change. The
key enabler is the Secure User Plane
Location technology that enables
handset manufacturers and others
to offer services direct to users in a
network-agnostic way. Finally, is the
increasing work ongoing on receiver
and antenna technology. From GPS
M-code user equipment projects in the
USA to adaptive antenna technology,
these developments are certainly
moving forward and will improve
still further the GNSS capabilities
across all application areas. |
| A myriad of
different devices |
Thomas Seiler
u-blox CEO |
In mobile telephones, positioning
information provided by GPS receivers
has become as common as Bluetooth.
The major trend in 2008 will be growth
in GPS attachments in a myriad of
different electronic devices. We anticipate
significant breakthroughs in many areas
of the consumer electronic market,
resulting from falling costs in integrating
positioning functionalities. This has
made the price of GPS negligible. The
industry has reached a level of maturity
that makes the availability of positioning
information of true value to users of
handheld devices. Today maps, points
of interest and other information are
readily available, something that was
not the case only two years ago.
The main drivers of the industry
are identifiable. Firstly, continued
improvements in mobile connectivity with
the many different wireless communication
technologies available make internet
connection possible, almost anywhere.
Modern mobile devices require accurate
positioning information to be useful. Here
wireless and positioning technologies
play hand-in-hand in providing additional
user benefits. Thus we believe that
more and more mobile terminals will
include an integrated GPS receiver.
Secondly, the economic benefits
derived from navigation information
boost the demand for GSP receivers
and wider scopes of their application.
Market penetration should continue
to increase, with alone the sales of
Personal Navigation Devices (PNDs)
being predicted to double in 2008.When
the promised modernizations of GPS
and commissioning of the GALILEO
satellite systems are finally realized,
better signal quality will allow further
expansion in the range of positioning
applications. Current receiver technology
has reached a very sophisticated and
mature level so that innovation will again
be accelerated by the new capabilities
provided by the satellites. |
