The current low-cost global navigation satellite systems (GNSS) receiver cannot calculate
satisfactory positioning results for pedestrian applications in urban areas with dense …

Currently, global navigation satellite system (GNSS) receivers can provide accurate and
reliable positioning service in open-field areas. However, their performance in the downtown …

This paper describes a GNSS software receiver architecture and the associated benefits in
terms of algorithm flexibility and processing efficiency. For the latter, different signal …

Carrier phase–based positioning using Global Navigation Satellite System (GNSS) signals
can provide centimeter-level accuracy; however, to do so requires robust, continuous …

The reliable and accurate localization of people and vehicles is one of the challenges of
intelligent transportation systems (ITS) s. This has led to a variety of technical approaches in …

eliable positioning in urban canyon, especially in dense urban areas, is difficult to achieve in
a cost-effective manner using standalone Global Navigation Satellite System (GNSS), due to …

The navigation system of a vehicle plays an important role in the vehicle's safety and control.
Such a system can be realized through the integration of a Global Positioning System (GPS) …
