Sensor-aided inertial navigation has successfully been used for decades for localization of a
roving body. When the rover is known to be stationary, artificial “stationary” measurements …

Unmanned aircraft system navigation in urban environments requires consideration of which
combination of sensors can provide the most accurate navigation results in a dynamically …

To enhance the performance of the inertial navigation system (INS)/global position system
(GPS) integrated navigation system for the land vehicle during GPS outages is an extremely …

This paper presents an overview of GNSSbased indoor location technologies. Current and
emerging users and their potential requirements are first discussed. Signal attenuation and …

Global Navigation Satellite Systems (GNSSs) suffer from the problems of invisible satellites
and multipath effect in urban canyons. Many approaches have been employed to eliminate …

Despite the prevalence of GPS services, they still suffer from intermittent positioning with
poor accuracy in partially shadowed regions like urban canyons, flyover shadows, and …

The research tests the accuracy of two consumer grade GPS devices and two GPS-enabled
Apple i-devices within an urban landscape. Data collection is an integral component to …

A test-bed application, called Map Matched GPS (MMGPS) processes raw GPS output data,
from RINEX files, or GPS derived coordinates. This developed method uses absolute GPS …

Vehicle constraints have been gaining increased popularity as a means to mitigate drift of
Inertial Navigation Systems in GNSS deprived settings. While useful, such constraints …

Collaborative driving is a growing domain of Intelligent Transportation Systems (ITS) that
makes use of communications to autonomously guide cooperative vehicles on an …
