STMicroelectronics Satellite-Tracking Chips Make a Mark on Europe's Navigation
ST and European Space Agency Performed the First-Ever Position Fix
Using GALILEO Satellites
GENEVA -- (Marketwired) -- 04/11/13 -- STMicroelectronics (NYSE:
STM), a global semiconductor leader serving customers across the
spectrum of electronic applications, today announced that its Teseo
II single-chip satellite-tracking ICs were successful in the very
first ground location test using Europe's own independent navigation
system, Galileo. The tests were conducted in collaboration with the
European Space Agency (ESA).
Last month, the first position fix of longitude, latitude and
altitude using the four Galileo satellites currently in orbit was
performed by the European Space Agency at its Technology Centre in
the Netherlands and by ST at its GNSS (Global Navigation Satellite
System) software development labs in Naples, Italy.
ST and ESA conducted the historic static and dynamic tests using a
rooftop antenna with a clear view of the satellites (static) and from
a mobile test-bed unit travelling in a normal user environment
(dynamic). The Teseo II receiver was able to track and produce a 3D
fix over the entire path of the mobile unit, using only the 4 Galileo
IOV (In-Orbit Validation) satellites.
ST and ESA plan to continue the joint tests, initially as a combined
multi-constellation fix with GPS and/or Glonass satellites, then
later in the year, when more Galileo satellites are available, they
also plan Galileo-only tests in a hostile environment.
ESA and ST have been cooperating on a project to evaluate the
performance of low-cost consumer and automotive GNSS receivers with
the Galileo signals, combining ESA's expertise in knowledge of the
signals, both theoretical and from monitoring, with ST's 20 years of
experience in producing chips to process satellite navigation
Low-cost receivers have narrower bandwidth and less-capable antennas,
but in the real world must operate in much more hostile situations
than professional test receivers. As the consumer receiver must
operate in urban-canyon situations when many of the signals are
reflections, greatly weakened and significantly distorted, ST's Teseo
II, with its multi-constellation capability and outstan
sensitivity, makes a perfect fit for many different consumer
"The historic milestone achieved in collaboration with the European
Space Agency is an excellent demonstration of the Galileo support on
ST's satellite navigation platform and reinforces our position as a
leading supplier of high-performance GNSS receivers for applications
like e-Call, Tolling, Telematics and Navigation," said Antonio
Radaelli, Infotainment Business Unit Director, STMicroelectronics.
"Furthermore, the outstanding capability of the Teseo II chips to use
signals from multiple satellite navigation systems enable consumers
to benefit from the Galileo navigation system before the satellite
constellation is fully populated."
Notes to Editors:
Introduced as the world's first single-chip positioning device for
multiple global navigation systems in January 2011, ST's Teseo II is
a single-chip standalone satellite receiver able to use signals from
all of the satellite navigation systems, including GPS, the European
GALILEO system, Russian GLONASS and Japanese QZSS. This allows the
receiver to keep many satellites in sight, delivering advantages such
as shorter time-to-first-fix and continuous tracking with enhanced
accuracy, even under challenging circumstances such as driving
through urban canyons.
ST is a global leader in the semiconductor
market serving customers across the spectrum of sense and power and
