Global Positioning System

2014
Global positioning system is now generally used during field investigations for obtaining precise locations but more importantly it has been employed to determine the plate movements. The results are used for determining the strain build-up in an area and seismic predictions.

RETOOLING the Global Positioning System

Scientific American, 2004
The article focuses on the capabilities of the Global Positioning System (GPS). Underlying improved capabilities is a series of system upgrades that include additional satellite signals, increased broadcast power, performance monitoring, guaranteed error bounds, smart antennas that can selectively direct and receive signals, and integration with ...

Protecting the global positioning system

IEEE Aerospace and Electronic Systems Magazine, 2005
A report published by the Volpe National Transportation Systems Center titled "Vulnerability Assessment of the Transportation Infrastructure Relying on the Global Positioning System" (29 August 2001) states that the civil transportation infrastructure, seeking the increased efficiency made possible by GPS, is developing a reliance on GPS that could ...

The global positioning system (navstar)

Bulletin Géodésique, 1979
In October 1978, the third of a series of prototype navigational satellites of an entirely new design was successfully launched. By the end of the first phase (1979) there will be six of these “NAVSTAR” satellites. They constitute one piece of a major development thrust to deploy a revolutionary navigation system called the Global Positioning System ...

Global Positioning System (GPS)

1998
Das USA-Verteidigungsministerium (Department of Defense, Abkurzung DOD) erteilte 1973 den Auftrag, ein satellitengestutztes System zu entwickeln, das die Bestimmung von Position und Geschwindigkeit von beliebigen ruhenden und sich bewegenden Objekten ermoglichte, um damit eine weltweite Navigation mit hoher Genauigkeit zu gewahrleisten.

overview of global positioning systems

2019
This chapter discusses the fundamentals of satellite navigation. It introduces the fundamentals of the global position estimation using time‐of‐arrival estimation of signals received from a cluster of satellites. The chapter assesses the impact of the satellite constellation geometry on the global positioning accuracy.

GPS - Global Positioning System

Informatik-Spektrum, 1996
Das GPS (global positioning system) ist ein satellitenbasiertes Positionsbestimmungssystem. Es gestattet weltweit mit etwa 400 DM teuren handlichen Endgeraeten den GPS-Empfaengern, eine kontinuierliche Echtzeit-Orts- und damit auch Geschwindigkeitsbestimmung zum Nulltarif. Das GPS-System besteht aus drei Komponenten: 24 GPS-Satelliten, die den fuer die

New optimal approach to Global Positioning System/Differential Global Positioning System integrity monitoring

Journal of Guidance, Control, and Dynamics, 1996
Summary: The problems of global positioning system (GPS) and differential GPS (DGPS) integrity monitoring are addressed. Receiver-autonomous and station-based integrity monitoring algorithms are discussed. Integrity monitoring consists of two functions: detection of the fact that a satellite channel produced wrong data and isolation or identification ...
