Spatial IT Application: Navigation System for Global Positioning System

Precision Position, Navigation, and Timing without the Global Positioning System

Real-Time Navigation Using the Global Positioning System

For more than a decade, TRW has been involved in aerospace applications of the Global Positioning System (GPS). TRW Ballistic Missiles Division first began working with GPS on a Minuteman missile test flight program in 1980. Since then, TRW has applied GPS to programs such as the Peacekeeper missile, the F-22 fighter aircraft, the Orbital Maneuvering Vehicle, Brilliant Pebbles, and classified s...

How is it made? Global Positioning System (GPS)

Recently, after a family trip, a friend of mine decided to go back to use his old paper map in his travels and to put his GPS receiver to rest for ever. This came after a series of deceptions by this little device with the annoying automated voice and the 4" screen and the constantly lost signal, his words notmine. The latest of these deceptions was a trip from Ottawa to Niagara Falls which too...

Application of Vectorized Attitude Determination Using Global Positioning System Signals

In this paper, an analysis of two techniques for finding a point-by-point (deterministic) attitude solution of a vehicle using Global Positioning System phase difference measurements is preformed. These techniques transform a general loss function into a more numerically efficient form. One technique determines three-dimensional vectors in the body coordinate system, and the other in the refere...

Global Positioning System (A Review)

Accurate measurement of physical activity is a pre-requisite to monitor population physical activity levels and design effective interventions. Global Positioning System (GPS) technology offers potential to improve the measurement of physical activity. This paper 1) reviews the extant literature on the application of GPS to monitor human movement, with a particular emphasis on free-living physi...
