WIRELESS - Single-Shot Position - Cell-Phone Location without Ephemeris - A new method enables the mobile phone to compute its own position using acquisition assistance data with increased resolution in some of the fields. It benefits network operators as they can deliver the best performance with minimum bandwidth requirements, making this especially relevant in emergency-call situations.

WIRELESS - Shadow Matching - Improved GNSS Accuracy in Urban Canyons - GNSS positioning in dense urban areas is unreliable. Shadow matching uses 3D building models to predict which satellites are visible from different locations and compares this with the measured satellite visibility to determine position. Presented are test results of a preliminary shadow-matching algorithm in a London urban canyon and discussion of practical implementation.

WIRELESS - Over-the-Air Test Method - A-GPS Antenna Performance - Traditional testing of A-GPS device performance over a cabled RF connection, bypassing the GPS antenna and associated circuitry, does not give a complete picture of real-world performance and user experience. The OTA methodology described here ensures that all GPS antenna and device design factors are taken into account.

WIRELESS - Opening Up Indoors - Japan's Indoor Messaging System: IMES - IMES has been developed to meet the challenges of indoor and deep indoor positioning, as a system that can be implemented in any device that has a GPS/GNSS receiver, without hardware modification. IMES can provide reliable 3D position data with a single transmitter device without performing range calculation.

WIRELESS J911: Fast Jammer Detection And Location Using Cell Phone Crowd-Sourcing Inexpensive, readily available GPS jammers constitute a threat to safety, national infrastructure, and industry revenue streams. Cell phones could incorporate GPS jam-to-noise (J/N) ratio detectors to provide timely interference detection and effective localization, with a flexible and updateable system using a crowd-processing function resident in software.

WIRELESS - EGNOS Gets to Work - Using the European Service with GPS-Equipped Mobile Phones - Satellite-based augmentation system corrections from the European Geostationary Navigation Overlay Service improve the positioning accuracy and user experience of GPS-enabled mobile phones, even if EGNOS satellites are not visible and even when the GNSS chipset in the phone does not support SBAS.
