In ionospheric modeling, the differential code biases (DCBs) are a non-negligible error source, which are routinely estimated by the different analysis centers of the International GNSS Service (IGS) as a by-product of their global ionospheric analysis. These are, however, estim…
Lower Earth orbits (LEO) have become the residence for a significant number of large space debris, most of which are defunct satellites and rocket upper stages. The said debris jeopardize regular spacecraft operations in LEO and act as sources of smaller debris as a result of co…
The study of dwarf galaxies is of great importance to understand galaxy formation and evolution on the smallest mass scales. According to the current cosmological paradigm, galaxies grows hierarchically from the accretion of smaller systems. The dwarf galaxies that we observe to…
