Due to the huge success of GPS in both military and civil applications, several other GNSSs have been developed, built, and operated in the last few decades. GNSS, regional, and augmentation systems are comprise a growing family that also includes GLONASS, Galileo, BeiDou, and Japan’s Quasi-Zenith Satellite System (QZSS). New members, such as the Global Indian Navigation System (GINS), are preparing to join in next decade.

Urban Positioning on a Smartphone

Urban Positioning on a Smartphone

The poor performance of GNSS user equipment in urban canyons in terms of both accuracy and solution availability is a well-known problem that arises where there are tall buildings or narrow streets. This situation is worse in the cross-street direction than in the along-street direction. (See Figure 1.)

GAO Report Highlights GPS Role in Vehicle Safety Apps

GAO Report Highlights GPS Role in Vehicle Safety Apps

Components of a Vehicle-to-Vehicle Crash Avoidance System. Sources: Crash Avoidance Metrics Partnership and GAO

A Government Accountability Office (GAO) report on intelligent transportation system (ITS) technologies released today (November 1, 2013) identified concerns about GPS accuracy and relative positioning that could limit its use in vehicle-to-vehicle (V2V) systems.

However, U.S. Department of Transportation (DoT) officials responding to the GAO study expressed confidence that the quality of GPS receivers in today’s automobiles will be sufficient to support V2V safety applications.
