SiRF Technology, Inc. was a pioneer in the commercial use of GPS technology for consumer applications. The company was founded in 1995 and was headquartered in San Jose, California. The company was acquired by CSR plc in 2009. On April 5, 2013, the formerly British-owned American-based company SiRF was acquired by the American company The Blackstone Group. SiRF manufactured 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. Wikipedia.

In this work, we propose a set-theoretic approach to collaborative position location for wireless networks. The proposed method borrows the concept from the parallel projection method (PPM), originally developed for signal recovery with inconsistent convex feasibility sets, modifies and extends the technique to an iterative and distributed numerical algorithm to estimate node locations, based on incomplete and noisy internode distance estimates. We demonstrate that in the case of noncollaborative position location, the proposed method is analytically equivalent to the parallel implementation of Kaczmarz Algorithm that is guaranteed to converge to a local minimizer and thus a stationary point. For collaborative position location, the proposed iterative PPM is computationally much more efficient than existing methods such as SDP and MDS-MAP, while achieving comparable or better localization accuracy and robustness to non-line-of-sight (NLOS) bias. Finally, our proposed method can be implemented in a parallel and distributed fashion, and is scalable for large network deployment. © 2011 IEEE.

GPS chip maker SiRF Technology has reduced first-quarter sales estimates and implemented a cost-savings plan that will cost about 50 people their jobs and result in the closure of SiRF’s offices in Stockholm and South San Francisco. Aside from general economic malaise softening demand for personal navigation systems, the other whammy for SiRF was a lousy mobile-TV market. According to the release, it’s getting out of the market altogether. “Although SiRF has made considerable progress on the development of its mobile TV technology, the market for mobile TV has been slow to ramp up. In view of this, the Company has stopped further product developments in the mobile TV space and will focus its efforts on its core business.” Much of the data has pointed to this, but companies, such as Broadcom, which has pushed its mobile TV chips into higher-volume production and Dish Networks, which recently bid $712 million for spectrum that can be used for mobile television, still haven’t gotten the memo. Either they can afford to play now at a loss, in hopes of a slow market eventually arriving, or they know something we don’t.

Earlier today, Google unveiled Latitude, a nifty little application for your smartphone (as long as it’s not an iPhone) that lets your friends locate you, and you them, on a map. It reminds me of that great Boost Mobile commercial, the one with the tagline, Where you at?! As the Google Mobile blog explains: Latitude is a new feature of Google Maps for mobile, as well as an iGoogle gadget, that allows you to share your location with your friends and to see their approximate locations, if they choose to share them with you. You can use your Google account to sign in and easily invite friends to Latitude from your existing list of contacts or by entering their email addresses. Google Talk is integrated with Latitude, so you and your friends can update your status messages and profile photos on the go and see what everyone is up to. You can also call, SMS, IM, or email each other within the app. In fact, Latitude is the result of a much bigger battle between Google and the mobile operators, of which location-based services are but one small part. As I have said so many times in the past, LBS is the next big pot of gold. Just this week, I wrote: “My big belief is that as we transition to an increasingly mobile world, the location beacon takes the role of the TCP, and most mobile services (and applications) find their context from this location beacon.” Panelists at our Mobilize conference last year were of the opinion that location is about adding relevancy to applications already being used. I’d put it a bit more bluntly: In the future, mobile applications without context provided by location-based services will be like pizza without cheese. We’ve already seen the rapid commoditization of the Global Position System (GPS) chips and hardware. Many of the GPS chipset vendors, such as Broadcom, Qualcomm, SiRF and CSR, have licensed Skyhook Wireless’ Wi-Fi positioning information, which adds depth to location-related information. In addition, there are many aggregators — Wavemarket, Loc-Aid and uLocate, for example — that sell network-centric location data as well. And in keeping with my theme from last night, I’d like to point out that there are already products on the market that do what Latitude promises. DodgeBall, a company Google itself bought, was doing something similar a few years ago. (Thanks Matt, for that link.) Of course Latitude could prove to be bad news for location startup Loopt. As one of our readers wrote, “Loopt has not cracked the code yet in terms of getting enough customers or getting PAID for the customers they do have.” Actually, Latitude is most similar to a friend locator offering from Useful Networks called Sniff, which is available on Sprint. In order to be effective on a larger scale, Sniff would have to do cross-carrier location information aggregation. They plan to announce more deals and trials at the Mobile World Congress in Barcelona later this month. In the meantime, with Latitude Google is moving to commoditize both the map information and the location beacon. Google is using triangulation data from cellular networks, and Wi-Fi positioning along with GPS data for its Latitude offering. It is only a matter of time before this location information is made available to other developers for free, especially Android app developers. After all, Google needs apps for its Android platform, and more importantly it needs developers to think differently. By doing so, it’s going after a potentially lucrative revenue stream for the carriers. As Stacey had noted, “Developers are charged each time their program asks a server for the GPS coordinates of the mobile device, making location-based services a potentially pricey feature.” North American carriers in particular are at risk here. They need a collective LBS aggregation strategy, and fast, according to Chetan Sharma, a mobile industry expert, which is where offerings from Qualcomm can help. But will those be enough? I don’t think so.

Smaller, lighter and longer. These are requirements for tracking devices of today. What sound like contradiction can be explained easily: Smaller dimensions, lower weight and longer battery running time. For such requirements Round Solutions offers the ORG4472 GPS module based on the brand new SiRF IV chipset. Available is a fully automotive and industrial compliant module – with only 7 x 7x 1.4 mm the smallest GPS module of the world. The ORG4472 is mounted by SMT (Surface Mount Technology). There are no cost s for RF connectors or cable and no manual work is need in production. Its integrated interface for accelerometers, gyrometers or other sensors makes “Dead Reckoning” easy. Using “Dead Reckoning” tracking can be continued even without sight to satellites, for example in tunnels. Free access to the test server www.track4less.com and www.track4free.com facilitates the use of geodata.

CSR, formerly Cambridge Silicon Radio, has bought SiRF, an American GPS chip company, in a share transaction valued at 91 million British pounds ($132.7 million), giving SiRF shareholders 27 percent of the new, enlarged CSR. Two SiRF directors will get seats on the board. SiRF is best known for its SiRFstar range of GPS chips, which are used by TomTom, Garmin, Palm, and others. CSR has traditionally specialized in Bluetooth chips, more recently concentrating on highly integrated all-in-one circuits that combine Bluetooth with other radio functions like Wi-Fi and FM reception. Lately, it has been promoting 802.11n for mobile applications, although industry uptake has yet to take off. The company has confirmed to me that it will continue to be called CSR, and will continue to have its headquarters in Cambridge, U.K.

CSR, formerly known as Cambridge Silicon Radio, has agreed to buy American GPS (global positioning system) chip expert, SiRF. The transaction values SiRF at £91 million, and gives SiRF shareholders 27 percent of the merged company. SiRF’s SiRFstar GPS chips are used in Tom Tom, Garmin, Palm and other system, while CSR is best known as a Bluetooth chip maker. CSR has been focusing on making combination chips, adding Wi-Fi, FM radio and GPS to its Bluetooth processors. The combined company will still be based in Cambridge UK. “GPS is next big growth market – and we are putting together world leader in GPS with world leader in Bluetooth,” Jeffrey Torrance, vice president of corporate development at CSR told eWEEK Europe. At the moment, only 20 percent of phones, at the high end of the market, have GPS in them, but that is expected to double in the next few years, he said. Phones are developing into a two-chip system, said Torrance. People had thought at one time that Bluetooth would eventually be absorbed into the main phone chip, so the phone is based around one processor and specialist companies like CSR would be out in the cold. Instead, things have evolved differently, with other radio technologies, such as Wi-Fi, FM and now GPS joining into the Bluetooth chip, said Torrance: “The phone is building up like a binary star – one chip for voice and the other is the connectivity centre. Our goal is to bring all those connectivity technologies together into one connectivity powerhouse.” CSR already has GPS, but has concentrated on eGPS, a form that uses triangulation between cellular base stations to locate a GPS handset, instead of the satellites used in conventional GPS. The two technologies are complementary, and can combine in A-GPS, where cellular location assists the conventional GPS: “It’s a continuum,” said Torrance.
