Equitable Allocation of Earth Observing Satellites Resources

Abstract: Large space projects like Earth Observing Satellites are often co-funded by several agents (countries, civil and military agencies, . . . ). Accordingly, their exploitation must take into account a specific requirement : the allocation of resources among the different agents must be equitable. But it must also be efficient, that is, the available resources must not be under-exploited....

Performance Modeling of Earth Resources Remote Sensors

A technique i s presented for constructing a mathematical model of an Earth resources remote sensor. The technique combines established models of electronic and optical components with formulated models of scan and vibration effects, and it includes a model of the radiation effects of the Earth’s atmosphere. The resulting composite model is useful for predicting in-flight sensor performance, an...

Rare Earth Elements—Critical Resources for High Technology

The rare earth elements (REE) form the largest chemically coherent group in the periodic table. Though generally unfamiliar, the REE are essential for many hundreds of applications. The versatility and specificity of the REE has given them a level of technological, environmental, and economic importance considerably greater than might be expected from their relative obscurity. The United States...

Bayesian Joint Inversions for the Exploration of Earth Resources

We propose a machine learning approach to geophysical inversion problems for the exploration of earth resources. Our approach is based on nonparametric Bayesian methods, specifically, Gaussian processes, and provides a full distribution over the predicted geophysical properties whilst enabling the incorporation of data from different modalities. We assess our method both qualitatively and quant...
