u-blox published whitepapers:
- The advantages of global 3G coverage for M2M applications (PDF, eBook)
Numerous telecommunication carriers worldwide are migrating from 2G to 3G services to accommodate the increased bandwidth required by modern smartphones and tablet computers. This migration has a direct impact on the requirements for 3G wireless modems used in machine-to-machine (M2M) applications. One of the main issues is the numerous and differing frequency bands used by 3G networks depending on carrier and geographic region. Other issues include interoperability with different Global Navigation Satellite Systems such as GPS, GLONASS, Galileo and QZSS, as well as hardware compatibility with other wireless standards such as GSM and CDMA. This paper examines these issues.
- Combining the best of UMTS with GPS (PDF, eBook)
The combination of mobile communications with global positioning, Internet and multimedia services in small, portable devices has become an accelerating industry trend, particularly for mobile resource management systems, connected automotive navigation systems and handheld consumer products. The result is attractive new location-based applications and services that were previously impossible with either technology alone: smart, self-upgrading navigators, sophisticated vehicle and personal trackers, smartphones and tablet PCs with rich multimedia and communications capabilities. This whitepaper highlights some important considerations when combining UMTS connectivity with GPS based on the LISA-U2 module series.
- Hybrid Positioning and CellLocateTM (PDF, eBook)
Although GPS is a widespread technology, GPS positioning is not always possible, particularly in shielded environments such as indoors and enclosed park houses, or when a GPS jamming signal is present. The situation can be improved by augmenting GPS receiver data with mobile network cell attributes to provide a level of redundancy that can benefit numerous applications. A hybrid solution making use of this technique has been realized by u-blox: CellLocate.
- u-blox' Solution for European eCall (PDF, eBook)
With the imminent deployment of European eCall in 2014, development of In-vehicle eCall Systems (IVS) is in full swing. The correct choice of components will have a large affect on time-to-market. Important factors to consider are the possibility to verify IVS designs before eCall is deployed, the ability to support design-in requirements of closely-coupled GPS and GSM subsystems, comprehensive software support, component-level certification of the GSM modem, forward compatibility with future wireless technologies, and the availability of automotive-grade GPS and GSM components in high-volume. This paper examines these requirements.
- u-blox 6 GPS receivers enhanced with many new features
With the latest firmware 7 upgrade of the u-blox 6 GPS receiver platform, many new and innovative features have been added resulting in immediate, cost-free benefits to users of both u-blox GPS chips and modules. This whitepaper summarizes the upgrades.
- The Promising Marriage of Wireless and GPS Technologies
As both mobile service providers and GPS device manufacturers struggle to find new profitable services to offer their customers, the convergence of wireless and GPS technologies is starting to bear fruit. By equipping global positioning terminals with a parallel wireless back-channel, a whole new realm of application possibilities emerge that would have been impossible with either technology alone.
- Automotive Dead Reckoning: An intelligent solution for modern urban navigation
Increasingly dense urban environments pose a significant problem to navigation systems based on the reception of extremely weak GPS satellite signals. As ever more systems (e.g. road pricing, fleet management, emergency services, etc.) depend on reliable, uninterrupted navigation, “Dead Reckoning” GPS is becoming increasingly important.
