INCREASING THE ACCURACY OF NAVIGATION DETERMINATION OF AIRCRAFT COORDINATES USING EPHEMERITIC COMPONENTS

System design and analysis of aerospace technique characteristics
The causes of ephemeris errors affecting the accuracy of determining the coordinates of an aircraft (UA) are analyzed. The analysis is confirmed by quantitative estimates.

Regularized variance component estimation method of MSBAS InSAR deformation inversion

International Journal of Remote Sensing
The Multi-Dimensional Small Baseline Subset Interferometric Synthetic Aperture Radar (MSBAS InSAR) technique significantly reduces the visual ambiguity caused by the single line of sight by integrating multi-orbit SAR data for joint solution.
