How to read a pass

AOS (acquisition of signal) is the moment the satellite rises above your horizon, LOS (loss of signal) when it sets. Maximum elevation tells how high it gets: low passes are short and weak because the signal crosses more atmosphere and the horizon blocks it, high passes are long and strong. See how to read a satellite pass.

Positions are computed from public orbital elements (CelesTrak / US Space Force 18th SDS) with the SGP4 model and are accurate to a few kilometres; amateur radio data from the SatNOGS DB (CC BY-SA).
