dbpprop:abstract
  • SiRF Technology Holdings, Inc. is a publicly traded company that manufactures a range of patented GPS chipsets and software for consumer navigation devices and systems. The chips are based on ARM controllers integrated with low-noise radio receivers to decode GPS signals at very low signal levels. SiRF chips also support SBAS to allow for differentially corrected positions. SiRFstar III architecture is designed to be useful in wireless and handheld location-based services (LBS) applications, for 2G, 2.5G, 3G asynchronous networks. The SiRFstarIII family is comprised of the GRF3w RF IC, the GSP3f digital section, and the GSW3 software that is API compatible with GSW2 and SiRFLoc. The chips have been adopted by major GPS manufacturers, including Sony, Garmin, TomTom and Magellan. A pioneer in the commercial use of GPS for consumer applications, the company was founded in 1995 and has its headquarters in San Jose, California. On 10 February 2009, UK wireless chip company CSR announced it was buying SiRF in a share deal worth 136 million dollars.
  • SiRF Technology ist ein Hersteller von Chipsätzen für das Global Positioning System. SiRF ist auch die Bezeichnung für die jeweiligen Produkte. SiRF-Chipsätze beherrschen sowohl das klassische NMEA-Protokoll als auch ein eigenes ebenfalls als SiRF bezeichnetes binäres Protokoll. Die Firma SiRF Technology Holdings, Inc. wurde 1995 gegründet und hat ihren Sitz im kalifornischen San José. Sie ist an der Technologiebörse NASDAQ gelistet. SiRF ist Mitglied der Open Handset Alliance. Im Jahr 2005 kaufte SiRF die komplette GPS-Chip-Fertigung (und den Verkauf) von Motorola für 20 Millionen US-Dollar. Im Jahr 2007 hat SiRF die Centrality Communications übernommen, einen Hersteller von GPS-Navigation-Chips. Der Kaufpreis lag bei 283 Millionen Dollar, die in bar und in Aktien ausgezahlt werden. Das in Redwood ansässige Unternehmen Centrality Communications fertigte Navigationslösungen und mobile Navigationsgeräte. Seit seiner Gründung im Jahr 1999 hat es diverse System-on-Chip-Lösungen für mobile Navigationsanwendungen wie die Atlas- und Titan-Navigationsprozessoren entwickelt. Im Zuge von Patent-Streitigkeiten und der Finanzkrise ab 2007 verlor der Aktienkurs im Zeitraum von 2006 bis 2009 über 98 % an Wert. Am 9. Februar 2009 kündigte die englische Firma Cambridge Silicon Radio (CSR) an, für ungefähr 91 Millionen Pfund Sterling (98,2 Millionen Euro) in Form von eigenen Aktien SiRF zu übernehmen.
  • SiRF Technology Holdings, Inc. on yhdysvaltalainen satelliittipaikannuksen piirejä valmistava yhtiö. Yhtiö on mukana NASDAQ-indeksissä. Yhtiö perustettiin vuonna 1995 ja sen pääkonttori on San Josessa, Kaliforniassa. Vuonna 2007 sen liikevaihto oli 330 miljoonaa dollaria, josta kolmannes oli voittoa. Sen johtajat ovat Diosdado P. Banatao ja Kanwar Chadha. Helmikuussa 2009 englantilainen CSR ilmoitti ostavansa SiRFin 136 miljoonalla dollarilla. .
  • SiRF è un marchio di microcontroller di proprietà di SiRF Technology Holdings, Inc. , progettato per essere usato nei sistemi GPS, che ha un suo linguaggio di programmazione. L'architettura SiRFstar III è progettata per essere usata su applicazioni wireless e portatili, per reti asincrone 2G, 2,5G e 3G. La famiglia SiRFstarIII è compresa di GRF3w RF IC, la sezione digitale GSP3f, e il software GSW3 che è API compatibile con GSW2 e SiRFLoc. I chip sono stati adottati dai grandi produttori di GPS come: Garmin, TomTom, NAVIGON e Magellan. La compagnia SiRF Technology Holdings, Inc. è stata fondata nel 1995 con sede a San Jose, California. È elencata al NASDAQ sotto il simbolo SIRF. Nel 2008 SiRF Technology annuncia di essere al lavoro di SiRFPrima, successore di SiRFstarIII.
  • SiRF Technology Holdings, Inc. é uma empresa que fabrica uma série de chipsets GPS e softwares para sistemas e dispositivos de navegação. Os chips são baseados em controladores ARM integrados com receptores de radio de baixo ruído para decodificar sinais GPS em níveis de sinal muito baixos (normalmente -160dBm).
