The Global Positioning System (GPS)

2017
This chapter presents an overview of the US Global Positioning System (GPS ), which became the first operational global navigation satellite system (GNSS ) core constellation when it was declared fully operational in 1995. First, the space segment is described, including key characteristics of the different satellite types.

Global Positioning System (GPS) autonomous navigation

IEEE Symposium on Position Location and Navigation. A Decade of Excellence in the Navigation Sciences, 2002
A system description, a discussion of design issues, and performance results obtained from the Aerospace Corporation simulation of the GPS autonomous navigation system (ANS) concept are given. Analysis methods, physical models, and pertinent equations are presented.

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

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.

GPS – Global positioning system

2013
Global positioning system (GPS) je mreža satelita koji kruže oko Zemlje na fiksnim točkama iznad planeta i koji odašilju signal prema Zemlji koji može primiti svatko s GPS prijemnikom. Ovi signali nose vremenski kod i zemljopisne podatke o položaju koji omogućuju korisniku da odrede svoj točan položaj, brzinu i vrijeme bilo gdje na planeti.

Global Positioning System (GPS) Autonomous User System

Navigation, 1988
A GPS autonomous navigation system will be operational with the GPS Block IIR satellites in the first decade of the twenty-first century. This system will provide the user with full navigation accuracy for 180 days even if the GPS Operational Control Segment (OCS) is inoperable.

Global Positioning System Surveying (GPS)

1995
This chapter is not intended to be a text on global positioning surveying. The bibliography contains many other sources that will greatly expand one’s knowledge of the topic to any depth or breadth required. The objective of the chapter is to provide information to eliminate problems commonly experienced by first time users of GPS technology.

Tracking African elephants with a global positioning system (GPS) radio collar.

Pachyderm, 1998
Reviews December 1996 to May 1997 Global Postioning System (GPS) trials based on results from two bulls radio collared in Amboseli NP: M86 (38 years and in musth when collared) tracked for 134 days, and M169 (34 years) tracked for 168 days.

Global Positioning Systems (GPS)

2014
We first explain the detailed calculation for determining the position and velocity of the GPS receiver. We then give the characteristics of different constellations of navigation satellites. We conclude with an appendix on GPS and relativity.
