Gaofen-3 (GF-3) is the only in-orbit SAR satellite of China civilian fields. It is designed especially for ocean observation but not for interferometric applications. However, during the past one and ...
The ZY-3 is the civil high-resolution optical stereoscopic mapping satellite independently developed by China. The ZY-3 constellation of the twin satellites operates in a sun-synchronous, near-polar, ...
GF-3 satellite, the first C band and full-polarization SAR satellite of China with spatial resolution of 1 m, was successfully launched in August 2016. We analyze the error sources of GF-3 satel...
WorldView-3, as a high-resolution commercial earth observation satellite, which is launched by Digital Global, provides panchromatic imagery of 0.31 m resolution. The positioning accuracy is les...
Using images to determine camera position and attitude is a consolidated method, very widespread for application like UAV navigation. In harsh environment, where GNSS could be degraded or denied, imag...
La photogrammétrie a connu une évolution croissante passant par les procédés analogique, semi- analytique et analytique qui étaient bien développés durant la deuxième moitié du siècle précédent. Ver...
In this paper we studied and examined the formulation of conservation laws on dynamic moving deforming meshes, in the context of the Geometric Conservation Law (GCL) compliant high order temporal and ...
A continuous adjoint method for Aerodynamic Shape Optimization (ASO) using the compressible Reynolds-Averaged Navier-Stokes (RANS) equa-tions and the Baldwin-Lomax turbulence model was implemented and...
The theory of non-oscillatory scalar schemes is developed in this paper in terms of the local extremum diminishing (LED) principle that maxima should not increase and minima should not decrease. This ...
The theory of non-oscillatory scalar schemes is developed in this paper in terms of the local extremum diminishing (LED) principle that maxima should not increase and minima should not decrease.
The Wide Area Augmentation System (WAAS) provides accuracy (95%) to better than 1m in horizontal and 2m in vertical, which is quite an improvement compared to the stand-alone GPS accuracy and well wit...
In the Joint Precision Approach and Landing System (JPALS) both the differential GPS reference station and the airborne user will employ Controlled Reception Pattern Array (CRPA) antennas.
Distance Measuring Equipment (DME) is seeing renewed interest for its ability to support future aviation navigation and surveillance needs. It is one of the primary technologies being examined by the ...
Accurate knowledge of position and orientation is a prerequisite for many applications regarding unmanned navigation, mapping, or environmental modelling. GPS-aided inertial navigation is the preferre...
In this paper, the experimental research utilized UAV imageries of two areas, assessed the accuracy of aerial triangulation on the basis of different photo-control points distributions using two kin...
