On-orbit Stellar Camera Calibration based on Space Resection with Multi-images
on-orbit calibration stellar camera space resection multi star images satellite attitude accuracy
2015/11/20
Due to the intense vibration and/or the change of space environmental factors such as temperature, pressure, etc., the stellar camera parameters might change during satellites launching or while orbit...
Impact of variability of space environmenton communications:Working Group 1 overview
environmenton communication
2015/9/14
The paper presents an overview of the scientific research carried out in the frames of Working Group 1 activities of the COST Action 271. The basic objective of this Working Group was the study of the...
The study of (m, 8)-systems is motivated by the problem of lower bounding the two-way complexity (in the sense of Yao [1]) of the Hamming distance function. Results in this direction will be contained...
Ionospheric Threats to Space-Based Augmentation System Development
Ionospheric Threats Space-Based Augmentation System Development
2015/6/26
The ionosphere contributes the largest and most unpredictable error to single frequency GPS users’ range measurements. The goal of a Space-Based Augmentation System (SBAS) in mitigating these ionosphe...
Methodology and Case Studies of Signal-in-Space Error Calculation Top-down Meets Bottom-up
Signal-in-Space Error Calculation Top-down Meets Bottom-up
2015/6/25
Signal in space (SIS) errors are a major error source for the Global Positioning System (GPS). They are defined as any errors related to satellite transmission, mainly satellite position and clock err...
GPS Signal-in-Space Anomalies in the Last Decade:Data Mining of 400,000,000 GPS Navigation Messages
GPS Signal-in-Space Data Mining GPS Navigation Messages
2015/6/25
For the Global Positioning System (GPS), signal-in-space(SIS) performance is key to the positioning accuracy and the integrity. In practice, SIS anomalies occasionally happens and the consequent user ...
Steffen Thoelert received his diploma degree in Electrical Engineering with fields of expertise in high-frequency engineering and communications at the University of Magdeburg in 2002. The next four y...
Statistical Characterization of GPS Signal-In-Space Errors
Statistical Characterization GPS Signal-In-Space Errors
2015/6/24
For most Global Positioning System (GPS) standard posi-tioning service (SPS) users, real-time satellite orbits and clocks are derived from predicted ephemeris and clock parameters in broadcast navigat...
As GLONASS has fully restored its constellation, there is an increasing desire to use multiple constellations to im-prove positioning performance. Knowledge of GLONASS signal-in-space (SIS) error beha...
GEOMETRIC ASPECTS OF THE HANDLING OF SPACE IMAGES
space images mathematical models orientation GIS
2015/5/12
Only few space images do have a perspective geometry like aerial cameras. But also the Russian perspective photos do have not
negligible systematic image errors. By this reason special mathematical m...
CLGVSM: Adapting Generalized Vector Space Model to Cross-lingual Document Clustering
CLGVSM Adapting Generalized Vector Space Model Cross-lingual Document Clustering
2013/6/27
Cross-lingual document clustering (CLDC) is the task to automatically or-ganize a large collection of cross-lingual documents into groups considering con-tent or topic. Different from the tradition-al...
On the MMSE Criterion for Space-Time Coded Signaling in the Presence of Unknown Interference
MMSE Criterion Space-Time Coded Signaling Unknown Interference
2009/9/4
The primary goal of this letter is to provide comparative assessments to the two cases where different criteria are used in joint over antenna minimum mean squared error (JA-MMSE) spatial filtering fo...
Discrete Array Representation of Continuous Space-time Source Distributions
slant stack transform ultra-wide band short-pulse signals continuous space-time source distribution
2009/7/28
We consider the realization of a continuous space-time source distributions using a sparse non-uniform point-source array. The construction determines the largest possible cells corresponding to the l...
