Global positioning system and discussion on its use(3)——application of GPS;

Global positioning system and its application(1)——history of development for navigation and positioning technology;

Research on GDOP of global positioning system;

Global Positioning System (GPS) is a radio navigation system which provides free users with accurate longitude, latitude and elevation of three-dimensional position information and time information.

With the continuous emergence of some new technologies and depth integration, these issues are getting resolved, including: Global Positioning System (GPS), Geographic Information System (GIS) and Intelligent Transportation System (ITS).

COMPARISON BETWEEN BEIDOU SATELLITE NAVIGATION SYSTEM AND GPS;

Application of GPS in Substations;

Application of GPS to Landslides Research in Xiakou;

The theory of the realization of global position system(GPS) receiver is studied in this paper,and the simple mathematical model is also introduced.

This unit combined global position system(GPS) with phase locked loop(PLL) technique,and made measured phasor to be sampled synchronously at different site,as well as sampling frequency to follow system frequency variance self-adapt.

With the ability of offering precise position and time synchronization information, the Global Position System(GPS) has substituted the traditional methods in more and more domains.
