TLDR
The objectives of the paper are to demonstrate that the 3D affine model and its modifications of the3D polynomial models are applicable to different satellite sensors and different types of terrain and under some conditions, the empirical models can produce accuracies close to those from rigorous mathematical models.About:

Bias-corrected rational polynomial coefficients for high accuracy geo-positioning of QuickBird stereo imagery
TL;DR: In this article, the performance of two schemes for orientation bias correction (i.e., RPCs modification and RPCs regeneration) is presented based on one separate-orbit QuickBird stereo image pair in Shanghai, and four cases for bias correction, including shift bias correction and second-order polynomial bias correction are examined.

Assessing geometric accuracy of the orthorectification process from GeoEye-1 and WorldView-2 panchromatic images
TL;DR: For attaining sub-pixel planimetric accuracies for the orthorectified GeoEye-1 Geo and WorldView-2 Ortho Ready Standard images and using RPC0 model with 7 GCPs, users should avoid off-nadir angles higher than 20° and use a very accurate DEM.

Using Stereo Satellite Imagery for Topographic and Transportation Applications: An Accuracy Assessment
TL;DR: In this paper, three mathematical models for satellite sensor modeling are used: Rational Function Model (RFM), 3D polynomial model, and 3D affine model to evaluate the level of accuracy that can be achieved by using stereo satellite images for different applications involving significantly different types of terrain.

Correcting bias in the rational polynomial coefficients of satellite imagery using thin-plate smoothing splines
Xiang Shen,Bin Liu,Qingquan Li +2 more
TL;DR: In this paper, a thin-plate spline model has been proposed to remove complex distortions in vendor-provided Rational Polynomial Coefficients (RPCs), such as the errors caused by short-period orbital perturbations.

Assessment of radargrammetric DSMs from TerraSAR-X Stripmap images in a mountainous relief area of the Amazon region
TL;DR: In this article, the feasibility of using Digital Surface Models (DSMs) extracted from TerraSAR-X Stripmap stereo-pair images for detailed topographic mapping was investigated for a mountainous area in the Carajas Mineral Province, located on the easternmost border of the Brazilian Amazon.

Bias compensation in rational functions for Ikonos satellite imagery
Clive S. Fraser,Harry B. Hanley +1 more
TL;DR: In this article, a method for the removal of exterior orientation biases in rational function coefficients (RPCs) for Ikonos imagery is developed, which can subsequently be compensated during spatial intersection by two additional parameters in image space that effect a translation of image coordinates.

Rational Functions and Potential for Rigorous Sensor Model Recovery
TL;DR: In this article, a least squares solution for RF parameter generation and geopositioning accuracy of Ikonos Geo stereo images was proposed and evaluated using simulated DEM data, ground control points by either refining the vendor-provided scene, and an aerial image.
