Space State Representation Product Evaluation in Satellite Position and Receiver Position Domain

Displaced squeezed number states: Position space representation, inner product, and some applications.

Position-Aware Non-negative Matrix Factorization for Satellite Image Representation

Satellite images clustering is a challenging problem in remote sensing and machine vision, where each image content is represented by a high-dimensional feature vector. However, the feature vectors might not be appropriate to express the semantic content of images, which eventually leads to poor results in clustering and classification. To tackle this problem, we propose a novel approach to gen...

Exhaustive global grid search in computing receiver position from modular satellite range measurements

A global grid search algorithm with an application in weak signal satellite positioning is implemented and tested numerically. The algorithm consists of local GaussNewton search and a global starting point chooser, and it can be generalized as a global optimization method for functions with an attraction basin of computable minimum radius. The method is shown to find the global minimum in a bou...

State Space Initiation for Blind Mobile Terminal Position Tracking

Blind localization and tracking of mobile terminals in urban scenarios is an important requirement for offering new locationbased services, handling emergency cases of nonsubscribed users, public safety, countering IEDs, and so forth. In this context, we propose a track-before-detect scheme taking explicitly advantage of multipath propagation in an urban terrain by using a priori information ab...

Time Domain Passivity Control for Position-Position Teleoperation Architectures

This article presents a method for passivating the communication channel of a symmetric position-position teleoperation architecture on the time domain. The time domain passivity control approach has recently gained appeal in the context of timedelayed teleoperation because passivity is not established as a design constraint, which often forces conservative rules, but rather as a property which...
