Phase compensated optical fiber links enable high accuracy atomic clocks separated by
thousands of kilometers to be compared with unprecedented statistical resolution. By …

We investigate a relativistic positioning system where the coordinates of the users are
determined by the proper times broadcasted by clocks in motion in spacetime: these are the …

We discuss the design for a discrete, immediate, simple relativistic positioning system (rPS)
which is potentially able of self-positioning (up to isometries) and operating without …

Current GNSS systems rely on global reference frames which are fixed to the Earth (via the
ground stations) so their precision and stability in time are limited by our knowledge of the …

The position of users located on the Earths surface or near it may be found with the classic
positioning systems (CPS). Certain information broadcast by satellites of global navigation …

Hemos realizado un estudio numérico detallado de la estructura de la región de emisión y
de la co-región. Se ha hecho para varios grupos de cuatro satélites pertenecientes a las …

Vsi trenutno operativni globalni navigacijski satelitski sistemi temeljijo na Newtonovem
opisu prostorcasa. Zanašajo se na globalne referencne sisteme, ki so vezani na Zemljo …
