Title: Discrete relativistic positioning systems
Abstract:
I will 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 calibration or ground control assistance. The design is discussed in 1 + 1 spacetimes, in Minkowski and Schwarzschild solutions, as well as in 2 + 1 spacetimes in Minkowski. I will sho in particular that the system is self-calibrating and robust under perturbations. The RPS can be adapted as detectors for the gravitational field and we shall briefly discuss their role in testing different theoretical settings for gravity. In fact, RPS is a natural candidate for a canonical method to extract observables out of a gravitational theory, and therefore to design experiments to test gravity.
