There are some global land-cover maps and they are used not only for various assessments of international organization but various researches such as GCM, ecosystem model, water resource model and land-use model. But the accuracy of global land-cover maps are not high and legends of maps are not unified. For example, MODIS land-cover ...

Verifying the velocity accuracy of a GPS receiver or an integrated GPS/INS system in a dynamic environment is a difficult proposition when many of the commonly used reference systems have velocity uncertainities of the same order of magnitude or greater than the GPS system. The results of flight tests aboard an aircraft in which multiple reference systems ...

The authors affirm that the ability to deliver a reconnaissance payload over 300 miles from a launch point to better than 35 m can be achieved by using a tightly integrated GPS (Global Positioning System)-inertial system. This system provides navigation, guidance, airframe and payload management functions for an unmanned air vehicle (UAV). High ...
This report contains the results of a Sandia National Laboratories Directed Research and Development (LDRD) program to investigate the integration of Global Positioning System (GPS) and inertial navigation system (INS) technologies toward the goal of optimizing the navigational accuracy of the combined GPSANS system. The approach ...

Efficient techniques for computing axisymmetric non-neutral plasma equilibria are described. These equilibria may be obtained either by requiring global thermal equilibrium, by specifying the midplane radial density profile, or by specifying the radial profile of [integral][ital n] [ital dz]. Both splines and finite-differences are used, and the ...
This paper presents an image network-based technology designed for long-range onboard rover localization. This integrated overhead and ground image network provides a global geometric configuration. Incorporation of this image network with our unique incremental bundle adjustment and visual odometry methodologies ensures optimal localization ...

. This paper presents a novel way of identifying and illustrating the accuracy in the particle tracing method for flow visualization. We make use of explicit Runge-Kutta methods for particle tracing in steady velocity fields, and describe three approaches to estimate the accuracy of the calculated path. These approaches are: ...
