POSITION ESTIMATION OF AERIAL VEHICLE BASED ON A VISION AIDED NAVIGATION SYSTEM
Navigation Pose Estimation Geo-Referencing Vision-Based Matching Fuzzy reasonning
2015/9/28
Automatic pose estimation remains to be one of the challenging problems in photogrammetry and computer vision. When other
systems (e.g. GPS and INS) are inadequate, and real time precise positioning...
A Local-Area GPS Pseudolite-Based Mars Navigation System
Local-Area GPS Pseudolite-Based Mars Navigation System
2015/6/29
Tasks envisioned for future generation Mars rovers sample collection, area survey, resource mining, habitat construction, etc.– will require greatly enhanced navigational capabilities over those posse...
Design and Performance Analysis of a Low-Cost Aided Dead Reckoning Navigation System
Dead Reckoning General Aviation DME GPS
2015/6/29
This paper presents an aided dead reckoning navigation system based on the fusion of inexpensive inertial, air data and magnetic sensors aided by a skeletal network of radio-navigation aids. In the fu...
There may be situations where positioning is required, but no service is available either due to signal blockage or cost of installing infrastructure.
We compared positioning performance of GPS and DGPS to that of GPS/DGPS integrated with non-interfering UWB transponders. Simulations of a simple test case predict 15% horizontal accuracy improvement ...
Performance of a Doppler-Aided GPS Navigation System for Aviation Applications under Ionospheric Scintillation
Performance Doppler-Aided GPS Navigation System Aviation Applications Ionospheric Scintillation
2015/6/25
Aircraft landing using the Global Positioning System (GPS) in equatorial regions is more difficult than in other regions because ionospheric scintillation is prevalent.Ionospheric scintillation causes...
Assessing the Security of a Navigation System:A Case Study using Enhanced Loran
Assessing Security Navigation System Enhanced Loran
2015/6/25
Global Navigation Satellite Systems (GNSS) has become increasingly interwoven into the fabric of our infrastructure and economic system. However, as GNSS becomes more important for safety of life and ...
A 3D Model Based Imdoor Navigation System for Hubei Provincial Museum
Three-dimensional Navigation Mobile Application Database
2014/4/21
3D models are more powerful than 2D maps for indoor navigation in a complicate space like Hubei Provincial Museum because they can provide accurate descriptions of locations of indoor objects (e.g., d...
Regionalized Lunar South Pole Surface Navigation System Analysis
Regionalized Lunar South Pole Surface Navigation System Analysis
2009/9/3
Apollo missions utilized Earth-based assets for navigation, since the landings took place at lunar locations in constant view from the Earth. The new exploration campaign to the lunar South Pole regio...
