A REDUNDANT GNSS-INS LOW-COST UAV NAVIGATION SOLUTION FOR PROFESSIONAL APPLICATIONS
UAV sreliable navigation sredundant IMUs sGNSS beamforming sclose coupling
2015/9/21
This paper presents the current results for the FP7 GINSEC project. Its goal is to build a pre-commercial prototype of a low-cost, accurate and reliable system for the professional UAV market. Low-cos...
Compressed Sensing with Coherent and Redundant Dictionaries
Compressed Sensing Coherent and Redundant Dictionaries
2015/6/17
This article presents novel results concerning the recovery of signals from undersampled data in the common situation where such signals are not sparse in an orthonormal basis or incoherent dictionary...
REDUNDANT IMUS FOR PRECISE TRAJECTORY DETERMINATION
Photogrammetry Sensor IMU Simulation Modelling Processing Acquisition
2015/5/29
A redundant inertial measurement unit (IMU) is an inertial sensing device composed by more than three accelerometers and three gyroscopes. This paper analyses the performance of redundant IMUs and the...
Generating Oriented Pointsets From Redundant Depth Maps Using Restricted Quadtrees
Matching Surface Three-dimensional Point Cloud Fusion Triangulation
2014/9/9
In this article we present an algorithm for the fusion of depth images derived by dense image matching (DIM). One key idea of our algorithm is to generate a 2D triangulation for each available depth m...
Fault processing policy based on dual-redundant control law for aero-engine control sensors
sensors health management digital control
2014/8/12
A fault processing policy was proposed for the circumstance under which all the dual-redundant closed-loop feedback control sensors went wrong. This policy was based on dual-redundant control law and ...
The Fastest Response Burst-mode Transmission Scheme Using Small Redundant Scrambler and AC-coupled Receiver with Fast Baseline Response
Optical communications Fiber optics links subsystems Networks star
2015/6/8
The fastest 10-nsec response with 21.5-dBm dynamic-range burst-mode transmission for 10G-PONs without any reset scheme is demonstrated using newly proposed small redundant scrambler and low-cost AC-co...
Probabilistic Analysis of a Robot System with Redundant Safety Units and Common-Cause Failures
robot safety availability reliability common-cause failures failure repair redundancy
2013/1/29
This paper presents reliability and availability analyses of a model representing a system having one robot and n-redundant safety units with common-cause failures. At least k safety units must functi...
Application of annotated paraconsistent logic to surveys conducted of self-administered questionnaires containing redundant questions
Annotated paraconsistent logics Para-Analyzer algorithm Redundancy
2010/1/19
Purpose: Opinion polls and evaluation questionnaires are routinely applied as a means to gauge the most diverse
topics and often result inconsistent, mainly because, as they are directed to the publi...
On inverse kinematics and kinetics of redundant space manipulator simulation
inverse kinematics and kinetics redundant manipulators space robotics optimization with constraints
2010/3/12
Redundant manipulators are nowadays favoured in several future space mission scenarios in order to enhance the skill and flexibility of the entire system. DLR, since many years, has been engaged in th...
