Approaches to relativistic positioning around Earth and error estimations
Neus Puchades, Diego Sáez
In the context of relativistic positioning, the coordinates of a given user may be calculated by using suitable information broadcast by a 4-tuple of satellites. Our 4-tuples belon…

Relativistic Positioning Systems: Numerical Simulations
Neus Puchades, Diego Sáez
The motion of satellite constellations similar to GPS and Galileo is numerically simulated and, then, the region where bifurcation (double positioning) occurs is appropriately repr…

Probing the creatable character of perturbed Friedmann-Robertson-Walker universes
Ramon Lapiedra, Diego Sáez
We discuss whether some perturbed Friedmann-Robertson-Walker (FRW) universes could be creatable, i. e., could have vanishing energy, linear momentum and angular momentum, as it cou…
