Cross-calibration is a fully automated algorithm for calibration of interferometric synthetic aperture radar (IFSAR) data. It has been developed for single-pass interferometry, but the principles may be applicable to multi-pass interferometry, too. The algorithm is based on natural distributed targets and it excels by neither requiring surveyed ground control points nor dedicated calibration sc...

In this work, we consider output-feedback distributed model predictive control (DMPC) based on state estimation with bounded process disturbances and output measurement noise. Specifically, a scheme observer-enhanced moving horizon (DMHE) is considered for purposes. The DMHE ensures that the estimates of system reach small neighborhood actual values quickly then maintain within neighborhood. Th...

This study highlights the benefit of precise aerial position control in the context of mapping using frame-based imagery taken by small UAVs. We execute several flights with a custom Micro Aerial Vehicle (MAV) octocopter over a small calibration field equipped with 90 signalized targets and 25 ground control points. The octocopter carries a consumer grade RGB camera, modified to insure precise ...

We consider the problem of steering a multiagent system to multiconsensus, namely regime where groups agents agree on given value, which may be different from group group. first address by using distributed proportional controllers that implement additional links in network modeling communication protocol among and introduce procedure for optimal selection them. Both cases single integrators se...

The CARTOSAT 1 satellite, launched by the Indian Space Research Organisation (ISRO) in 2005, can provide panchromatic alongtrack stereo imagery with a ground resolution of 2.5 m. Along with the imagery, encrypted files with rational polynomial coefficients (RPCs) and meta-data are distributed by ISRO. The RPCs allow direct georeferencing within certain limits depending on the on-board systems f...
