SiRF’s Next-generation GPS Technology Brings Benefits of Location Awareness to More Consumer Platforms and Users
SiRF Technology, Inc. today announced two new global
positioning system chip set families that deliver such high levels of performance, power savings,
cost effectiveness and system integration that the world’s largest consumer electronics manufacturers are
using them to enable a new range of innovative wireless, consumer electronic, automotive and mobile
computing products. These new products, in combination with today’s announcements of relationships
with Motorola and Matsushita Electric Works extend SiRF’s lead in the GPS chip set and IP
licensing market.
The two new product families are designed to address the emerging needs of the
consumer GPS market: lower power for longer battery life, lower cost to accelerate mainstream
consumer acceptance, and smaller size to enable a compact new class of handheld and wearable
devices.
The new products include the SiRFstarIIe/LP and the SiRFstarIIt families. With its
dramatic power efficiency, high sensitivity and modular design, the SiRFstarIIe/LP delivers
longer battery life and faster integration of GPS location technology into consumer devices such
SiRF’s Next-generation GPS Technology Brings Location Awareness to More Consumers as cell phones and mobile computer accessories.
The SiRFstarIIt family is designed for low
power and lower system cost implementations of GPS in automobile navigation and mobile
compute system motherboards by using an innovative new architecture that shares system
resources to reduce the incremental cost of the GPS function.
Our vision is to drive GPS further into the mainstream. These new low-power product
families enable our OEM partners to develop market leading products that meet a broad range of
price, performance and functionality needs of consumers, according to Kanwar Chadha, founder
and vice president of marketing for SiRF Technology. With these new options, manufacturers
have a choice. If the desired consumer platform already possesses a powerful microprocessor,
they can use our new SiRFstarIIt to reduce system cost by sharing host resources. If not, the new
SiRFstar IIe/LP delivers all the horsepower needed for GPS and other functions to enable them
to run non-GPS applications in parallel – representing a major space and money saver.
SiRFstarIIe/LP: optimized for wireless handhelds and modular GPS designs
An extension to the highly popular SiRFstarIIe chip set, the new SiRFstarIIe/LP chip set
combines the industry’s highest GPS performance with extremely low power consumption and
higher CPU throughput. The current draw is only 60mA, which directly translates to longer
battery life – a critical requirement in portable devices such as cellular phones, personal locators
and handheld devices. SiRF’s TricklePower advanced power management technology reduces
power consumption still further.
With an embedded ARM7TDMI microprocessor, the SiRFstarIIe/LP features 55% more
CPU throughput than its predecessor, in many cases eliminating the need for a separate processor
to run non-GPS tasks, and thus dramatically reducing costs for many GPS consumer products.
As a highly integrated and self contained chip set, the SiRFstarIIe/LP is also well suited for use
in stand-alone GPS modules and subsystems.
The SiRFstarIIe/LP is fully compatible with SiRFLoc high sensitivity technology,
which provides autonomous and network aided GPS functionality in areas where traditional GPS
will not work, such as urban canyons, tunnels and even some indoor locations.
SiRFLoc is
designed to meet the coverage and accuracy requirements of both the FCC’s E-911 mandate as
well as the emerging location based services market.

SiRFstarIIt: reducing cost by putting GPS on the motherboard
The SiRFstarIIt chip set is architected to deliver lower power, smaller size and lower
system cost by integrating the GPS function directly onto the system motherboard. A further step
in SiRF’s vision of integrating GPS functionality more tightly and economically into highvolume
products, SiRFstarIIt consists of the GSP2t GPS tracker chip which calculates GPS
measurements; and SiRFNav software, which runs on the host system and calculates a final
navigation and position data. This allows sharing of host system processing and memory
resources, thereby delivering far lower system cost and smaller size. This is an extremely costeffective
solution for applications that use GPS as part of a multifunction system such as vehicle
navigation applications or motherboard mobile computing applications.
As mobile computing platforms are adopted by enterprise users, interest in location
technologies is growing, according to Gerry Purdy, CEO and president of Mobile Insights.
SiRF’s new products provide PDA manufacturers with a low-cost, low-power option either as a
peripheral or integrated directly onto the motherboard.
New technology already being adopted
The two new technologies are already being adopted by leading manufacturers including
Matsushita Electric Works, Lowrance, Navman, Leadtek, Royaltek and others.
SiRF is now the worldwide leader in GPS chip set volume, having overtaken the
incumbents in five years’ time, according to Will Strauss, president of Forward Concepts. I
attribute this success to the company’s ability to listen to manufacturers’ needs, and then meet
them by providing multiple product families to meet the diverse range of market needs – with
continual innovation in critical areas such as smaller form factors, lower power consumption,
and high performance and accuracy.
Based on SiRFstarII architecture
Both products are based on the SiRFstarII architecture, providing the high performance
GPS common to all SiRFstarII receivers. At the core of the SiRFstarII is the Satellite Signal
Tracking Engine, a patented GPS engine that integrates key functionality into a tight
architecture. This design enables the SiRFstarII’s unique set of features including SnapStart
for quick start-up, SnapLock for fast acquisition, and FoliageLock for high sensitivity.
SiRFstarII also features a built-in Wide Area Augmentation System capability for
SiRF’s Next-generation GPS Technology Brings Location Awareness to More Consumers
enhanced accuracy, advanced multi-path rejection for better accuracy in harsh environments, and
TricklePower advanced power management for extended battery life.
Both the SiRFstarIIe/LP and the SiRFstarIIt families consist of RF IC, baseband IC and
software. Both the baseband ICs, GSP2e/LP and GSP2t are built using 0.18 micron CMOS
processes for low power. The RF IC GRF2i/LP utilizes a low power bipolar process technology.
