The sun-synchronous IKONOS orbit provides global coverage, consistent access times, and near-nadir viewing angles. The system is capable of 1:10,000 scale mapping without ground control and 1:2400 scale mapping with ground control. The IKONOS ground station produces radiometrically corrected images, georectified images, orthorectified images, stereo pairs, and digital elevation models (DEMs) for image analysis photogrammetric and cartographic applications. This article provides an overview of the IKONOS satellite, ground systems, products, and applications.

By incorporating a priori constraints into the adjustment model, multiple independent images can be adjusted with or without ground control. The RPC block adjustment model presented in this paper is directly related to geometric properties of the physical camera model. Multiple physical camera model parameters having the same net effect on the object-image relationship are replaced by a single adjustment parameter. Consequently, the proposed method is numerically more stable than the traditional adjustment of exterior and interior orientation parameters. This method is generally applicable to any photogrammetric camera with a narrow field of view, calibrated, stable interior orientation, and accurate a priori exterior orientation data. As demonstrated in the paper, for Ikonos satellite imagery, the RPC block adjustment achieves the same accuracy as the ground station block adjustment with the full physical camera model.
