SiRF GPS Technology to be Used in Vehicle Tracking Modules for Automotive Marketplace

March 18, 2002

SiRF Technology, Inc. announced Mar. 18 that Sony Ericsson MobileCommunications (USA) will use SiRF's global positioning system (GPS)technology to location-enable a family of modules for the fleet management and telematics markets. These products, to bedeveloped and marketed by the Sony Ericsson M2M Com (Machine toMachine Communication) Business Unit, will be powered by the SiRFstarIIe chipset to provide positioning andnavigation information.

These products will be used primarily in fleet management andtelematics applications. According to the company, fleet management is a fast-growing market fortracking and managing large fleets of vehicles including trucks,delivery vehicles, taxis, and more. The market for telematics -- thecombination of location-aware devices in the automobile and wirelesslinks to location-based services -- is expected to grow explosivelyover the next five years. Strategy Analytics estimates that by 2007,up to 55% of new cars produced in the U.S., Europe, and Japan willhave built-in telematics functions.

"With their clear leadership in telecommunications and consumerelectronics, we expect Sony Ericsson to be a major player in thefast-growing telematics and fleet management markets," according toKanwar Chadha, founder and vice president of marketing at SiRFTechnology. "We believe this alliance will help SiRF to advance itslead as the premier supplier to the automotive GPS market, which isand will continue to be an important market for us." Specific products will be announced later in 2002.

SiRFstarII Architecture

According to the company, the SiRFstarII architecture provides complete GPS functionalitywith the high performance necessary for telematics and fleetmanagement, in which fast start-up (or time to first fix -- TTFF),high fix density, and accuracy in obscured sky environments iscrucial. With its unique set of features such as SnapStart forquick start-up, SnapLock for fast acquisition, and FoliageLockfor high sensitivity, the SiRFstarII architecture provides enhancedGPS-based location information in urban canyons and dense foliage --where traditional GPS architectures fall short. The SiRFstarIIbaseband IP core provides a library of modular and portable buildingblocks, along with a complete set of tools, to enable integrationinto customer designs. SiRF has also developed technologyimplementations to facilitate and optimize GPS integration intospecific platforms, such as automobiles, cell phones, and personaldigital assistants.
