Abstract

Establishing communication links between mobile terminals, such as smartphones or vehicle communication systems, and non-terrestrial networks (NTNs), for instance, low earth orbit satellite constellations, can be impacted by frequent variations in signal characteristics as satellites move. If a static antenna configuration on a mobile device does not adapt to this dynamic signal environment, link degradation may result. A system for dynamic antenna configuration can use a pre-calculated look-up table (LUT) that maps various satellite positions and signal properties to corresponding antenna tune states. During operation, a predictive algorithm on the terminal can use real-time signal strength measurements and the LUT to estimate a satellite's trajectory. This estimation can narrow the search for a subsequent tune state to a localized subset of the LUT, which can enable the terminal to proactively reconfigure its antenna hardware. Such a reconfiguration may improve the performance of the NTN link.
