| | A new software technology uses a navigation overlay algorithm between GPS measurements and a GIS database that describes 2D footprints of buildings. This software middleware is laid under the embedded navigation application, providing it with improved position fixes, resulting in an average improvement of cross-track errors by a factor of 3. |

| GNSS Accuracy: Lies, Damn Lies, and Statistics
| | | This update to a seminal article first published here in 1998 explains how statistical methods can create many different position accuracy measures. As the driving forces of positioning and navigation change from survey and precision guidance to location-based services, E911, and so on, some accuracy measures have fallen out of common usage, while others have blossomed. The analysis changes further when the constellation expands to ombinations of GPS, SBAS, Galileo, and GLONASS. Software scripts, provided online, help bridge the gap between theory and reality. |

 | Optimizing Indoor GPS Performance
| | | GPS was never intended for indoor environments, and indeed, the relatively weak satellite signals do not readily lend themselves to use in such environments. The Federal Communications Commission's E911 mandate has spurred significant effort in the GPS community to apply its combined expertise to solve this dilemma. |
